// LAGraph_BF_full1: Bellman-Ford single source shortest paths, returning both
// the path lengths and the shortest-path tree.
// LAGraph_BF_full1 performs a Bellman-Ford to find out shortest path, parent
// nodes along the path and the hops (number of edges) in the path from given
// source vertex s in the range of [0, n) on graph given as matrix A with size
// n*n. The sparse matrix A has entry A(i, j) if there is an edge from vertex i
// to vertex j with weight w, then A(i, j) = w.
// LAGraph_BF_full1 returns GrB_SUCCESS if it succeeds. In this case, there
// are no negative-weight cycles in the graph, and d, pi, and h are returned.
// The vector d has d(k) as the shortest distance from s to k. pi(k) = p+1,
// where p is the parent node of k-th node in the shortest path. In particular,
// pi(s) = 0. h(k) = hop(s, k), the number of edges from s to k in the shortest
// path.
// If the graph has a negative-weight cycle, GrB_NO_VALUE is returned, and the
// GrB_Vectors d(k), pi(k) and h(k) (i.e., *pd_output, *ppi_output and
// *ph_output respectively) will be NULL when negative-weight cycle detected.
// Otherwise, other errors such as GrB_OUT_OF_MEMORY, GrB_INVALID_OBJECT, and
// so on, can be returned, if these errors are found by the underlying
// GrB_* functions.

% ColorMatrixImage() applies color transformation to an image. This method
% permits saturation changes, hue rotation, luminance to alpha, and various
% other effects. Although variable-sized transformation matrices can be used,
% typically one uses a 5x5 matrix for an RGBA image and a 6x6 for CMYKA
% (or RGBA with offsets). The matrix is similar to those used by Adobe Flash
% except offsets are in column 6 rather than 5 (in support of CMYKA images)
% and offsets are normalized (divide Flash offset by 255).
%
% The format of the ColorMatrixImage method is:
%
% Image *ColorMatrixImage(const Image *image,
% const KernelInfo *color_matrix,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image.

% pixels in-place (without a copy) if the image is in RAM, or in a
% memory-mapped file. The returned pointer should *never* be deallocated
% by the user.
%
% Pixels accessed via the returned pointer represent a simple array of type
% PixelPacket. If the image type is CMYK or the storage class is PseudoClass,
% call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to obtain
% the black color component or the colormap indexes (of type IndexPacket)

% GaussJordanElimination() returns a matrix in reduced row echelon form,
% while simultaneously reducing and thus solving the augumented results
% matrix.
%
% See also http://en.wikipedia.org/wiki/Gauss-Jordan_elimination
%
% The format of the GaussJordanElimination method is:
%
% MagickBooleanType GaussJordanElimination(double **matrix,
% double **vectors,const size_t rank,const size_t number_vectors)
%
% A description of each parameter follows:
%
% o matrix: the matrix to be reduced, as an 'array of row pointers'.
%
% o vectors: the additional matrix argumenting the matrix for row reduction.
% Producing an 'array of column vectors'.
%
% o rank: The size of the matrix (both rows and columns).
% Also represents the number terms that need to be solved.
%
% o number_vectors: Number of vectors columns, argumenting the above matrix.
% Usally 1, but can be more for more complex equation solving.
%
% Note that the 'matrix' is given as a 'array of row pointers' of rank size.
% That is values can be assigned as matrix[row][column] where 'row' is
% typically the equation, and 'column' is the term of the equation.
% That is the matrix is in the form of a 'row first array'.
%
% However 'vectors' is a 'array of column pointers' which can have any number
% of columns, with each column array the same 'rank' size as 'matrix'.
%
% This allows for simpler handling of the results, especially is only one
% column 'vector' is all that is required to produce the desired solution.
%
% For example, the 'vectors' can consist of a pointer to a simple array of
% doubles. when only one set of simultanious equations is to be solved from
% the given set of coefficient weighted terms.
%
% double **matrix = AcquireMagickMatrix(8UL,8UL);
% double coefficents[8];
% ...
% GaussJordanElimination(matrix, &coefficents, 8UL, 1UL);
%
% However by specifing more 'columns' (as an 'array of vector columns',
% you can use this function to solve a set of 'separable' equations.
%
% For example a distortion function where u = U(x,y) v = V(x,y)
% And the functions U() and V() have separate coefficents, but are being
% generated from a common x,y->u,v data set.
%
% Another example is generation of a color gradient from a set of colors at
% specific coordients, such as a list x,y -> r,g,b,a.
%
% You can also use the 'vectors' to generate an inverse of the given 'matrix'
% though as a 'column first array' rather than a 'row first array'. For
% details see http://en.wikipedia.org/wiki/Gauss-Jordan_elimination

% LeastSquaresAddTerms() adds one set of terms and associate results to the
% given matrix and vectors for solving using least-squares function fitting.
%
% The format of the AcquireMagickMatrix method is:
%
% void LeastSquaresAddTerms(double **matrix,double **vectors,
% const double *terms,const double *results,const size_t rank,
% const size_t number_vectors);
%
% A description of each parameter follows:
%
% o matrix: the square matrix to add given terms/results to.
%
% o vectors: the result vectors to add terms/results to.
%
% o terms: the pre-calculated terms (without the unknown coefficent
% weights) that forms the equation being added.
%
% o results: the result(s) that should be generated from the given terms
% weighted by the yet-to-be-solved coefficents.
%
% o rank: the rank or size of the dimensions of the square matrix.
% Also the length of vectors, and number of terms being added.
%
% o number_vectors: Number of result vectors, and number or results being
% added. Also represents the number of separable systems of equations
% that is being solved.
%
% Example of use...
%
% 2 dimensional Affine Equations (which are separable)
% c0*x + c2*y + c4*1 => u
% c1*x + c3*y + c5*1 => v

% ClutImage() replaces each color value in the given image, by using it as an
% index to lookup a replacement color value in a Color Look UP Table in the
% form of an image. The values are extracted along a diagonal of the CLUT
% image so either a horizontal or vertial gradient image can be used.
%
% Typically this is used to either re-color a gray-scale image according to a
% color gradient in the CLUT image, or to perform a freeform histogram
% (level) adjustment according to the (typically gray-scale) gradient in the
% CLUT image.
%
% When the 'channel' mask includes the matte/alpha transparency channel but
% one image has no such channel it is assumed that that image is a simple
% gray-scale image that will effect the alpha channel values, either for
% gray-scale coloring (with transparent or semi-transparent colors), or
% a histogram adjustment of existing alpha channel values. If both images
% have matte channels, direct and normal indexing is applied, which is rarely
% used.
%
% The format of the ClutImage method is:
%
% MagickBooleanType ClutImage(Image *image,Image *clut_image)
% MagickBooleanType ClutImageChannel(Image *image,
% const ChannelType channel,Image *clut_image)
%
% A description of each parameter follows:
%
% o image: the image, which is replaced by indexed CLUT values
%
% o clut_image: the color lookup table image for replacement color values.

% o channel: the channel.

% SigmoidalContrastImage() adjusts the contrast of an image with a non-linear
% sigmoidal contrast algorithm. Increase the contrast of the image using a
% sigmoidal transfer function without saturating highlights or shadows.
% Contrast indicates how much to increase the contrast (0 is none; 3 is
% typical; 20 is pushing it); mid-point indicates where midtones fall in the
% resultant image (0 is white; 50% is middle-gray; 100% is black). Set
% sharpen to MagickTrue to increase the image contrast otherwise the contrast
% is reduced.

* Example problem:
*
* The following test simulates a simple 1D heat equation,
* u_t = k*u_xx + f
* for t in [0, 10], x in [0, 1], with initial conditions
* u(0,x) = 0
* Dirichlet boundary conditions, i.e.
* u_t(t,0) = u_t(t,1) = 0,
* and a heating term of the form
* f = 2*exp(-200*(x-0.25)*(x-0.25))
* - exp(-400*(x-0.7)*(x-0.7))
* + exp(-500*(x-0.4)*(x-0.4))
* - 2*exp(-600*(x-0.55)*(x-0.55));
*
* The spatial derivatives are computed using a three-point
* centered stencil (second order for a uniform mesh). The data
* is initially uniformly distributed over N points in the interval
* [0, 1], but as the simulation proceeds the mesh is adapted.
*
* This program solves the problem with a DIRK method, solved with
* a Newton iteration and SUNLinSol_PCG linear solver, with a
* user-supplied Jacobian-vector product routine.

/// Map from one topological element in a mesh to another, with input
/// arrays on the source topology (at sparsely indexed locations) and the
/// destination topology, and with outputs on the destination topology.
/// In this gather version of the operation, the inputs on the destination
/// topology are sparsely indexed and the outputs are compacted, i.e.
/// the outputs are densely indexed 0 to n-1.

% GetVirtualPixels() returns an immutable pixel region. If the
% region is successfully accessed, a pointer to it is returned, otherwise
% NULL is returned. The returned pointer may point to a temporary working
% copy of the pixels or it may point to the original pixels in memory.
% Performance is maximized if the selected region is part of one row, or one
% or more full rows, since there is opportunity to access the pixels in-place
% (without a copy) if the image is in memory, or in a memory-mapped file. The
% returned pointer must *never* be deallocated by the user.
%
% Pixels accessed via the returned pointer represent a simple array of type
% Quantum. If the image type is CMYK or the storage class is PseudoClass,
% call GetAuthenticMetacontent() after invoking GetAuthenticPixels() to
% access the meta-content (of type void) corresponding to the
% region.
%
% If you plan to modify the pixels, use GetAuthenticPixels() instead.
%
% Note, the GetVirtualPixels() and GetAuthenticPixels() methods are not thread-
% safe. In a threaded environment, use GetCacheViewVirtualPixels() or
% GetCacheViewAuthenticPixels() instead.

% QueueAuthenticPixels() queues a mutable pixel region. If the region is
% successfully initialized a pointer to a Quantum array representing the
% region is returned, otherwise NULL is returned. The returned pointer may
% point to a temporary working buffer for the pixels or it may point to the
% final location of the pixels in memory.
%
% Write-only access means that any existing pixel values corresponding to
% the region are ignored. This is useful if the initial image is being
% created from scratch, or if the existing pixel values are to be
% completely replaced without need to refer to their pre-existing values.
% The application is free to read and write the pixel buffer returned by
% QueueAuthenticPixels() any way it pleases. QueueAuthenticPixels() does not
% initialize the pixel array values. Initializing pixel array values is the
% application's responsibility.
%
% Performance is maximized if the selected region is part of one row, or
% one or more full rows, since then there is opportunity to access the
% pixels in-place (without a copy) if the image is in memory, or in a
% memory-mapped file. The returned pointer must *never* be deallocated
% by the user.
%
% Pixels accessed via the returned pointer represent a simple array of type
% Quantum. If the image type is CMYK or the storage class is PseudoClass,
% call GetAuthenticMetacontent() after invoking GetAuthenticPixels() to
% obtain the meta-content (of type void) corresponding to the region.
% Once the Quantum (and/or Quantum) array has been updated, the
% changes must be saved back to the underlying image using
% SyncAuthenticPixels() or they may be lost.

/*! \brief This namespace is to organize functions that are useful when operating on the AST.
\defgroup frontendSageUtilityFunctions SAGE III utility functions(SageInterface)
\ingroup ROSE_FrontEndGroup
The Sage III IR design attempts to be minimalist. Thus additional functionality is
intended to be presented using separate higher level interfaces which work with the IR.
The namespace, SageInterface, collects functions that operate on the IR and are supportive of numerous types of routine operations required to support general analysis and transformation of the AST.
\internal Further organization of the functions in this namespace is required.
Major AST manipulation functions are scattered in the following directories
- src/midend/astUtil/astInterface
- src/roseSupport/utility_function.h, namespace ROSE
- src/roseSupport/TransformationSupport.h, class TransformationSupport
- src/midend/astInlining/inlinerSupport.C
- src/frontend/SageIII/sageInterface
- projects: such as outliner, OpenMP_Translator
Some other utility functions not related AST can be found in
- src/util/stringSupport/string_functions.h, namespace StringUtility
- src/roseExtensions/dataStructureTraversal/helpFunctions.C
- projects/dataStructureGraphing/helpFunctions.C
\todo A number of additional things to do:
- Pull scope handling out of EDG/Sage III translation so that is is made
available to anyone else building the Sage III IR from scratch (which
when it gets non-trivial, involves the manipulation of scopes).
- Other stuff ...

% RaiseImage() creates a simulated three-dimensional button-like effect
% by lightening and darkening the edges of the image. Members width and
% height of raise_info define the width of the vertical and horizontal
% edge of the effect.
%
% The format of the RaiseImage method is:
%
% MagickBooleanType RaiseImage(const Image *image,
% const RectangleInfo *raise_info,const MagickBooleanType raise,
% ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o raise_info: Define the width and height of the raise area.
%
% o raise: A value other than zero creates a 3-D raise effect,
% otherwise it has a lowered effect.
%
% o exception: return any errors or warnings in this structure.

bottom_radius Set bootom edge to this radius (radial scaling)
By default, if the radii arguments are nor provided the image radius
is calculated so the horizontal center-line is fits the given arc
without scaling.
The output image size is ALWAYS adjusted to contain the whole image,
and an offset is given to position image relative to the 0,0 point of
the origin, allowing users to use relative positioning onto larger
background (via -flatten).
The arguments are converted to these coefficients
c0: angle for center of source image
c1: angle scale for mapping to source image
c2: radius for top of source image
c3: radius scale for mapping source image
c4: centerline of arc within source image
Note the coefficients use a center angle, so asymptotic join is
furthest from both sides of the source image. This also means that
for arc angles greater than 360 the sides of the image will be
trimmed equally.

% DistortImage() distorts an image using various distortion methods, by

% usally of the same size as the source image, unless 'bestfit' is set to
% true.
%
% If 'bestfit' is enabled, and distortion allows it, the destination image is
% adjusted to ensure the whole source 'image' will just fit within the final

% many cases the virtual offset of the source image will be taken into
% account in the mapping.
%
% If the '-verbose' control option has been set print to standard error the
% equicelent '-fx' formula with coefficients for the function, if practical.

%
% Image *DistortImage(const Image *image,const DistortMethod method,
% const size_t number_arguments,const double *arguments,
% MagickBooleanType bestfit, ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image to be distorted.
%
% o method: the method of image distortion.
%
% ArcDistortion always ignores source image offset, and always
% 'bestfit' the destination image with the top left corner offset
% relative to the polar mapping center.
%
% Affine, Perspective, and Bilinear, do least squares fitting of the
% distrotion when more than the minimum number of control point pairs
% are provided.
%
% Perspective, and Bilinear, fall back to a Affine distortion when less
% than 4 control point pairs are provided. While Affine distortions
% let you use any number of control point pairs, that is Zero pairs is
% a No-Op (viewport only) distortion, one pair is a translation and
% two pairs of control points do a scale-rotate-translate, without any
% shearing.
%
% o number_arguments: the number of arguments given.
%
% o arguments: an array of floating point arguments for this method.
%
% o bestfit: Attempt to 'bestfit' the size of the resulting image.
% This also forces the resulting image to be a 'layered' virtual
% canvas image. Can be overridden using 'distort:viewport' setting.
%
% o exception: return any errors or warnings in this structure
%
% Extra Controls from Image meta-data (artifacts)...
%
% o "verbose"
% Output to stderr alternatives, internal coefficents, and FX
% equivalents for the distortion operation (if feasible).
% This forms an extra check of the distortion method, and allows users
% access to the internal constants IM calculates for the distortion.
%
% o "distort:viewport"
% Directly set the output image canvas area and offest to use for the
% resulting image, rather than use the original images canvas, or a
% calculated 'bestfit' canvas.
%
% o "distort:scale"
% Scale the size of the output canvas by this amount to provide a
% method of Zooming, and for super-sampling the results.
%
% Other settings that can effect results include
%
% o 'interpolate' For source image lookups (scale enlargements)

<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@ref kmeans.h implements a number of algorithm for **K-means
quantization**: Lloyd @cite{lloyd82least}, an accelerated version by
Elkan @cite{elkan03using}, and a large scale algorithm based on
Approximate Nearest Neighbors (ANN). All algorithms support @c float
or @c double data and can use the $l^1$ or the $l^2$ distance for
clustering. Furthermore, all algorithms can take advantage of multiple
CPU cores.
Please see @subpage kmeans-fundamentals for a technical description of
K-means and of the algorithms implemented here.
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@section kmeans-starting Getting started
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
The goal of K-means is to partition a dataset into $K$
“compact” clusters. The following example demonstrates
using @ref kmeans.h in the C programming language to partition @c
numData @c float vectors into compute @c numCenters clusters using
Lloyd's algorithm:
@code
#include <vl/kmeans.h>
double energy ;
double * centers ;
// Use float data and the L2 distance for clustering
KMeans * kmeans = vl_kmeans_new (VLDistanceL2, VL_TYPE_FLOAT) ;
// Use Lloyd algorithm
vl_kmeans_set_algorithm (kmeans, VlKMeansLloyd) ;
// Initialize the cluster centers by randomly sampling the data
vl_kmeans_init_centers_with_rand_data (kmeans, data, dimension, numData, numCenters) ;
// Run at most 100 iterations of cluster refinement using Lloyd algorithm
vl_kmeans_set_max_num_iterations (kmeans, 100) ;
vl_kmeans_refine_centers (kmeans, data, numData) ;
// Obtain the energy of the solution
energy = vl_kmeans_get_energy(kmeans) ;
// Obtain the cluster centers
centers = vl_kmeans_get_centers(kmeans) ;
@endcode
Once the centers have been obtained, new data points can be assigned
to clusters by using the ::vl_kmeans_quantize function:
@code
vl_uint32 * assignments = vl_malloc(sizeof(vl_uint32) * numData) ;
float * distances = vl_malloc(sizeof(float) * numData) ;
vl_kmeans_quantize(kmeans, assignments, distances, data, numData) ;
@endcode
Alternatively, one can directly assign new pointers to the closest
centers, without bothering with a ::VlKMeans object.
There are several considerations that may impact the performance of
KMeans. First, since K-means is usually based local optimization
algorithm, the **initialization method** is important. The following
initialization methods are supported:
Method | Function | Description
---------------|-----------------------------------------|-----------------------------------------------
Random samples | ::vl_kmeans_init_centers_with_rand_data | Random data points
K-means++ | ::vl_kmeans_init_centers_plus_plus | Random selection biased towards diversity
Custom | ::vl_kmeans_set_centers | Choose centers (useful to run quantization only)
See @ref kmeans-init for further details. The initialization methods
use a randomized selection of the data points; the random number
generator init is controlled by ::vl_rand_init.
The second important choice is the **optimization algorithm**. The
following optimization algorithms are supported:
Algorithm | Symbol | See | Description
------------|------------------|-------------------|-----------------------------------------------
Lloyd | ::VlKMeansLloyd | @ref kmeans-lloyd | Alternate EM-style optimization
Elkan | ::VlKMeansElkan | @ref kmeans-elkan | A speedup using triangular inequalities
ANN | ::VlKMeansANN | @ref kmeans-ann | A speedup using approximated nearest neighbors
See the relative sections for further details. These algorithm are
iterative, and stop when either a **maximum number of iterations**
(::vl_kmeans_set_max_num_iterations) is reached, or when the energy
changes sufficiently slowly in one iteration (::vl_kmeans_set_min_energy_variation).
All the three algorithms support multithreaded computations. The number
of threads used is usually controlled globally by ::vl_set_num_threads.

@tableofcontents
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
Given $n$ points $\bx_1,\dots,\bx_n \in \real^d$, the goal of K-means
is find $K$ `centers` $\bc_1,\dots,\bc_m \in \real^d$ and
`assignments` $q_1,\dots,q_n \in \{1,\dots,K\}$ of the points to the
centers such that the sum of distances
\[
E(\bc_1,\dots,\bc_k,q_1,\dots,q_n)
= \sum_{i=1}^n \|\bx_i - \bc_{q_i} \|_p^p
\]
is minimized. $K$-means is obtained for the case $p=2$ ($l^2$ norm),
because in this case the optimal centers are the means of the input
vectors assigned to them. Here the generalization $p=1$ ($l^1$ norm)
will also be considered.
Up to normalization, the K-means objective $E$ is also the average
reconstruction error if the original points are approximated with the
cluster centers. Thus K-means is used not only to group the input
points into cluster, but also to `quantize` their values.
K-means is widely used in computer vision, for example in the
construction of vocabularies of visual features (visual words). In
these applications the number $n$ of points to cluster and/or the
number $K$ of clusters is often large. Unfortunately, minimizing the
objective $E$ is in general a difficult combinatorial problem, so
locally optimal or approximated solutions are sought instead.
The basic K-means algorithm alternate between re-estimating the
centers and the assignments (@ref kmeans-lloyd). Combined with a good
initialization strategy (@ref kmeans-init) and, potentially, by
re-running the optimization from a number of randomized starting
states, this algorithm may attain satisfactory solutions in practice.
However, despite its simplicity, Lloyd's algorithm is often too slow.
A good replacement is Elkan's algorithm (@ref kmeans-elkan), which
uses the triangular inequality to cut down significantly the cost of
Lloyd's algorithm. Since this algorithm is otherwise equivalent, it
should often be preferred.
For very large problems (millions of point to clusters and hundreds,
thousands, or more clusters to find), even Elkan's algorithm is not
sufficiently fast. In these cases, one can resort to a variant of
Lloyd's algorithm that uses an approximated nearest neighbors routine
(@ref kmeans-ann).
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@section kmeans-init Initialization methods
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
All the $K$-means algorithms considered here find locally optimal
solutions; as such the way they are initialized is important. @ref
kmeans.h supports the following initialization algorithms:
@par Random data samples
The simplest initialization method is to sample $K$ points at random
from the input data and use them as initial values for the cluster
centers.
@par K-means++
@cite{arthur07k-means} proposes a randomized initialization of the
centers which improves upon random selection. The first center $\bc_1$
is selected at random from the data points $\bx_1, \dots, \bx_n $ and
the distance from this center to all points $\|\bx_i - \bc_1\|_p^p$ is
computed. Then the second center $\bc_2$ is selected at random from
the data points with probability proportional to the distance. The
procedure is repeated to obtain the other centers by using the minimum
distance to the centers collected so far.
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@section kmeans-lloyd Lloyd's algorithm
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
The most common K-means method is Lloyd's algorithm
@cite{lloyd82least}. This algorithm is based on the observation that,
while jointly optimizing clusters and assignment is difficult,
optimizing one given the other is easy. Lloyd's algorithm alternates
the steps:
1. **Quantization.** Each point $\bx_i$ is reassigned to the center
$\bc_{q_j}$ closer to it. This requires finding for each point the
closest among $K$ other points, which is potentially slow.
2. **Center estimation.** Each center $\bc_q$ is updated to minimize
its average distances to the points assigned to it. It is easy to
show that the best center is the mean or median of the points,
respectively if the $l^2$ or $l^1$ norm is considered.
A naive implementation of the assignment step requires $O(dnK)$
operations, where $d$ is the dimensionality of the data, $n$ the
number of data points, and $K$ the number of centers. Updating the
centers is much cheaper: $O(dn)$ operations suffice to compute the $K$
means and a slightly higher cost is required for the medians. Clearly,
the bottleneck is the assignment computation, and this is what the
other K-means algorithm try to improve.
During the iterations, it can happen that a cluster becomes empty. In
this case, K-means automatically **“restarts” the
cluster** center by selecting a training point at random.
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@section kmeans-elkan Elkan's algorithm
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
Elkan's algorithm @cite{elkan03using} is a variation of Lloyd
alternate optimization algorithm (@ref kmeans-lloyd) that uses the
triangular inequality to avoid many distance calculations when
assigning points to clusters. While much faster than Lloyd, Elkan's
method uses storage proportional to the umber of clusters by data
points, which makes it unpractical for a very large number of
clusters.
The idea of this algorithm is that, if a center update does not move
them much, then most of the point-to-center computations can be
avoided when the point-to-center assignments are recomputed. To detect
which distances need evaluation, the triangular inequality is used to
lower and upper bound distances after a center update.
Elkan algorithms uses two key observations. First, one has
\[
\|\bx_i - \bc_{q_i}\|_p \leq \|\bc - \bc_{q_i}\|_p / 2
\quad\Rightarrow\quad
\|\bx_i - \bc_{q_i}\|_p \leq \|\bx_i - \bc\|_p.
\]
Thus if the distance between $\bx_i$ and its current center
$\bc_{q_i}$ is less than half the distance of the center $\bc_{q_i}$
to another center $\bc$, then $\bc$ can be skipped when the new
assignment for $\bx_i$ is searched. Checking this requires keeping
track of all the inter-center distances, but centers are typically a
small fraction of the training data, so overall this can be a
significant saving. In particular, if this condition is satisfied for
all the centers $\bc \not= \bc_{q_i}$, the point $\bx_i$ can be
skipped completely. Furthermore, the condition can be tested also
based on an upper bound $UB_i$ of $\|\bx_i - \bc_{q_i}\|_p$.
Second, if a center $\bc$ is updated to $\hat{\bc}$, then the new
distance from $\bx$ to $\hat{\bc}$ is bounded from below and above by
\[
\|\bx - \bc\|_p - \|bc - \hat\bc\|_p
\leq
\|\bx - \hat{\bc}\|_p
\leq
\|\bx - \hat{\bc}\|_p + \|\bc + \hat{\bc}\|_p.
\]
This allows to maintain an upper bound on the distance of $\bx_i$ to
its current center $\bc_{q_i}$ and a lower bound to any other center
$\bc$:
@f{align*}
UB_i & \leftarrow UB_i + \|\bc_{q_i} - \hat{\bc}_{q_i} \|_p \\
LB_i(\bc) & \leftarrow LB_i(\bc) - \|\bc -\hat \bc\|_p.
@f}
Thus the K-means algorithm becomes:
1. **Initialization.** Compute $LB_i(\bc) = \|\bx_i -\hat \bc\|_p$ for
all points and centers. Find the current assignments $q_i$ and
bounds $UB_i$ by finding the closest centers to each point: $UB_i =
\min_{\bc} LB_i(\bc)$.
2. **Center estimation.**
1. Recompute all the centers based on the new means; call the updated
version $\hat{\bc}$.
2. Update all the bounds based on the distance $\|\bc - \hat\bc\|_p$
as explained above.
3. Set $\bc \leftarrow \hat\bc$ for all the centers and go to the next
iteration.
3. **Quantization.**
1. Skip any point $\bx_i$ such that $UB_i \leq \frac{1}{2} \|\bc_{q_i} - \bc\|_p$
for all centers $\bc \not= \bc_{q_i}$.
2. For each remaining point $\bx_i$ and center $\bc \not= \bc_{q_i}$:
1. Skip $\bc$ if
\[
UB_i \leq \frac{1}{2} \| \bc_{q_i} - \bc \|
\quad\text{or}\quad
UB_i \leq LB_i(\bc).
\]
The first condition reflects the first observation above; the
second uses the bounds to decide if $\bc$ can be closer than the
current center $\bc_{q_i}$ to the point $\bx_i$. If the center
cannot be skipped, continue as follows.
3. Skip $\bc$ if the condition above is satisfied after making the
upper bound tight:
\[
UB_i = LB_i(\bc_{q_i}) = \| \bx_i - \bc_{q_i} \|_p.
\]
Note that the latter calculation can be done only once for $\bx_i$.
If the center cannot be skipped still, continue as follows.
4. Tighten the lower bound too:
\[
LB_i(\bc) = \| \bx_i - \bc \|_p.
\]
At this point both $UB_i$ and $LB_i(\bc)$ are tight. If $LB_i <
UB_i$, then the point $\bx_i$ should be reassigned to
$\bc$. Update $q_i$ to the index of center $\bc$ and reset $UB_i
= LB_i(\bc)$.

@section kmeans-ann ANN algorithm
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
The *Approximate Nearest Neighbor* (ANN) K-means algorithm
@cite{beis97shape} @cite{silpa-anan08optimised} @cite{muja09fast} is a
variant of Lloyd's algorithm (@ref kmeans-lloyd) uses a best-bin-first
randomized KD-tree algorithm to approximately (and quickly) find the
closest cluster center to each point. The KD-tree implementation is
based on @ref kdtree.
The algorithm can be summarized as follows:
1. **Quantization.** Each point $\bx_i$ is reassigned to the center
$\bc_{q_j}$ closer to it. This starts by indexing the $K$ centers
by a KD-tree and then using the latter to quickly find the closest
center for every training point. The search is approximated to
further improve speed. This opens up the possibility that a data
point may receive an assignment that is *worse* than the current
one. This is avoided by checking that the new assignment estimated
by using ANN is an improvement; otherwise the old assignment is
kept.
2. **Center estimation.** Each center $\bc_q$ is updated to minimize
its average distances to the points assigned to it. It is easy to
show that the best center is the mean or median of the points,
respectively if the $l^2$ or $l^1$ norm is considered.
The key is to trade-off carefully the speedup obtained by using the
ANN algorithm and the loss in accuracy when retrieving neighbors. Due
to the curse of dimensionality, KD-trees become less effective for
higher dimensional data, so that the search cost, which in the best
case is logarithmic with this data structure, may become effectively
linear. This is somehow mitigated by the fact that new a new KD-tree
is computed at each iteration, reducing the likelihood that points may
get stuck with sub-optimal assignments.
Experiments with the quantization of 128-dimensional SIFT features
show that the ANN algorithm may use one quarter of the comparisons of
Elkan's while retaining a similar solution accuracy.
