The Square Root Normal Field (SRNF) framework is a method in the area of
shape analysis that defines a (pseudo) distance between unparametrized
surfaces. For piecewise linear (PL) surfaces it was recently proved that the
SRNF distance between unparametrized surfaces is equivalent to the Wasserstein

Algorithmic systems are often called upon to assist in high-stakes decision
making. In light of this, algorithmic recourse, the principle wherein
individuals should be able to take action against an undesirable outcome made
by an algorithmic system, is receiving growing attention. The bulk of the
literature on algorith... | http://arxiv.org/abs/2309.06969v1 |
A common practice in metric learning is to train and test an embedding model
for each dataset. This dataset-specific approach fails to simulate real-world
scenarios that involve multiple heterogeneous distributions of data. In this
regard, we introduce a novel metric learning paradigm, called Universal Metric

RRAM-based multi-core systems improve the energy efficiency and performance
of CNNs. Thereby, the distributed parallel execution of convolutional layers
causes critical data dependencies that limit the potential speedup. This paper
presents synchronization techniques for parallel inference of convolutional
layers on RR... | http://arxiv.org/abs/2309.03805v4 |
The aim of object-centric vision is to construct an explicit representation
of the objects in a scene. This representation is obtained via a set of
interchangeable modules called \emph{slots} or \emph{object files} that compete
for local patches of an image. The competition has a weak inductive bias to
preserve spatial... | http://arxiv.org/abs/2305.19550v1 |
Plants are a paradigm for active shape control in response to stimuli. For
instance, it is well-known that a tilted plant will eventually straighten
vertically, demonstrating the influence of both an external stimulus, gravity,
and an internal stimulus, proprioception. These effects can be modulated when a
potted plant... | http://arxiv.org/abs/2309.08950v1 |
Using a concept of filter we propose one generalization of Riemann integral,
that is integration with respect to filter. We study this problem, demonstrate
different properties and phenomena of filter integration. | http://arxiv.org/abs/2309.10879v1 |
The emergence of order in nature manifests in different phenomena, with
synchronization being one of the most representative examples. Understanding
the role played by the interactions between the constituting parts of a complex
system in synchronization has become a pivotal research question bridging
network science a... | http://arxiv.org/abs/2306.00237v1 |
We present a DNN accelerator that allows inference at arbitrary precision
with dedicated processing elements that are configurable at the bit level. Our
DNN accelerator has 8 Processing Elements controlled by a RISC-V controller
with a combined 8.2 TMACs of computational power when implemented with the
recent Alveo U25... | http://arxiv.org/abs/2301.00290v1 |
In this paper, we consider the optimization problem Submodular Cover (SCP),
which is to find a minimum cardinality subset of a finite universe $U$ such
that the value of a submodular function $f$ is above an input threshold $\tau$.
In particular, we consider several variants of SCP including the general case,
the case ... | http://arxiv.org/abs/2309.14558v1 |
Photons are emitted at all stages of relativistic heavy-ion collisions and do
not interact with the medium strongly. With access to the versatility of RHIC,
measurements of low momentum direct photons are made possible across different
system size and beam energies. An excess of direct photons, above prompt photon
prod... | http://arxiv.org/abs/2309.04993v1 |
Many bosons can occupy a single quantum state without a limit. This state is
described by quantum-mechanical Bose-Einstein statistics, which allows the
formation of a Bose-Einstein condensate at low temperatures and high particle
densities. Photons, historically the first considered bosonic gas, were late to
show this ... | http://arxiv.org/abs/2307.00081v2 |
Inspired by presentations by the authors during a workshop organized at the
Princeton Center for Theoretical Science (PCTS) in January 2022, we present a
perspective on some of the outstanding questions related to the "physics of the
ground beneath our feet." These identified challenges are intrinsically shared
with th... | http://arxiv.org/abs/2308.00162v1 |
