On Blocking Collisions between People, Objects and other Robots | Intentional or unintentional contacts are bound to occur increasingly more
often due to the deployment of autonomous systems in human environments. In
this paper, we devise methods to computationally predict imminent collisions
between objects, robots and people, and use an upper-body humanoid robot to
block them if ... | 1 | 0 | 0 | 0 | 0 | 0 |
Increasing Papers' Discoverability with Precise Semantic Labeling: the sci.AI Platform | The number of published findings in biomedicine increases continually. At the
same time, specifics of the domain's terminology complicates the task of
relevant publications retrieval. In the current research, we investigate
influence of terms' variability and ambiguity on a paper's likelihood of being
retrieved. We o... | 1 | 0 | 0 | 0 | 0 | 0 |
On topological obstructions to global stabilization of an inverted pendulum | We consider a classical problem of control of an inverted pendulum by means
of a horizontal motion of its pivot point. We suppose that the control law can
be non-autonomous and non-periodic w.r.t. the position of the pendulum. It is
shown that global stabilization of the vertical upward position of the pendulum

Automated Refactoring: Can They Pass The Turing Test? | Refactoring is a maintenance activity that aims to improve design quality
while preserving the behavior of a system. Several (semi)automated approaches
have been proposed to support developers in this maintenance activity, based on
the correction of anti-patterns, which are "poor solutions" to recurring design

Free fermions on a piecewise linear four-manifold. II: Pachner moves | This is the second in a series of papers where we construct an invariant of a
four-dimensional piecewise linear manifold $M$ with a given middle cohomology
class $h\in H^2(M,\mathbb C)$. This invariant is the square root of the torsion
of unusual chain complex introduced in Part I (arXiv:1605.06498) of our work,

Scalable Metropolis-Hastings for Exact Bayesian Inference with Large Datasets | Bayesian inference via standard Markov Chain Monte Carlo (MCMC) methods such
as Metropolis-Hastings is too computationally intensive to handle large
datasets, since the cost per step usually scales like $O(n)$ in the number of
data points $n$. We propose the Scalable Metropolis-Hastings (SMH) kernel that
exploits Gau... | 1 | 0 | 0 | 1 | 0 | 0 |
Regularization of the Kernel Matrix via Covariance Matrix Shrinkage Estimation | The kernel trick concept, formulated as an inner product in a feature space,
facilitates powerful extensions to many well-known algorithms. While the kernel
matrix involves inner products in the feature space, the sample covariance
matrix of the data requires outer products. Therefore, their spectral
properties are t... | 0 | 0 | 0 | 1 | 0 | 0 |
Fixing an error in Caponnetto and de Vito (2007) | The seminal paper of Caponnetto and de Vito (2007) provides minimax-optimal
rates for kernel ridge regression in a very general setting. Its proof,
however, contains an error in its bound on the effective dimensionality. In
this note, we explain the mistake, provide a correct bound, and show that the

Supervised Typing of Big Graphs using Semantic Embeddings | We propose a supervised algorithm for generating type embeddings in the same
semantic vector space as a given set of entity embeddings. The algorithm is

and achieve... | 1 | 0 | 0 | 0 | 0 | 0 |
Flexible Attributed Network Embedding | Network embedding aims to find a way to encode network by learning an
embedding vector for each node in the network. The network often has property
information which is highly informative with respect to the node's position and
role in the network. Most network embedding methods fail to utilize this
information durin... | 1 | 0 | 0 | 0 | 0 | 0 |
Attention Please: Consider Mockito when Evaluating Newly Proposed Automated Program Repair Techniques | Automated program repair (APR) has attracted widespread attention in recent
years with substantial techniques being proposed. Meanwhile, a number of

Communication Modalities for Supervised Teleoperation in Highly Dexterous Tasks - Does one size fit all? | This study tries to explain the connection between communication modalities

peg transfer. It was found that as the complexity of the task escalates, the
combination lin... | 1 | 0 | 0 | 0 | 0 | 0 |
Learning in anonymous nonatomic games with applications to first-order mean field games | We introduce a model of anonymous games with the player dependent action

Asynchronous Accelerated Proximal Stochastic Gradient for Strongly Convex Distributed Finite Sums | In this work, we study the problem of minimizing the sum of strongly convex
functions split over a network of $n$ nodes. We propose the decentralized and

themselves finite sums with $m$ components. ADFS converges linearly when local
functions are... | 1 | 0 | 0 | 0 | 0 | 0 |
Intermediate curvatures and highly connected manifolds | We show that after forming a connected sum with a homotopy sphere, all
(2j-1)-connected 2j-parallelisable manifolds in dimension 4j+1, j > 0, can be
equipped with Riemannian metrics of 2-positive Ricci curvature. When j=1 we
extend the above to certain classes of simply-connected non-spin 5-manifolds.

Structured Differential Learning for Automatic Threshold Setting | We introduce a technique that can automatically tune the parameters of a

A new fractional derivative of variable order with non-singular kernel and fractional differential equations | In this paper, we introduce two new non-singular kernel fractional

Safe Semi-Supervised Learning of Sum-Product Networks | In several domains obtaining class annotations is expensive while at the same

so far such app... | 1 | 0 | 0 | 1 | 0 | 0 |
A Structured Approach to the Analysis of Remote Sensing Images | The number of studies for the analysis of remote sensing images has been

insights, it tel... | 0 | 0 | 0 | 1 | 0 | 0 |
Approximations of the Restless Bandit Problem | The multi-armed restless bandit problem is studied in the case where the
pay-off distributions are stationary $\varphi$-mixing. This version of the
problem provides a more realistic model for most real-world applications, but
