Episodic training, where an agent's environment is reset after every success
or failure, is the de facto standard when training embodied reinforcement
learning (RL) agents. The underlying assumption that the environment can be
easily reset is limiting both practically, as resets generally require human
effort in the re... | http://arxiv.org/abs/2303.17600v1 |
Diffusion models learn to reverse the progressive noising of a data
distribution to create a generative model. However, the desired continuous
nature of the noising process can be at odds with discrete data. To deal with
this tension between continuous and discrete objects, we propose a method of
performing diffusion o... | http://arxiv.org/abs/2309.02530v2 |
This work proposes an energy-efficient Directional Modulation (DM) scheme for
on-body Internet of Things (IoT) devices. DM performance is tested using a
5-port stacked-patch MIMO antenna under two scenarios: a free space case and
using a four-layer human forearm phantom to simulate the user's wrist. It is
demonstrated ... | http://arxiv.org/abs/2301.06174v1 |
Understanding generalization is crucial to confidently engineer and deploy
machine learning models, especially when deployment implies a shift in the data
domain. For such domain adaptation problems, we seek generalization bounds
which are tractably computable and tight. If these desiderata can be reached,
the bounds c... | http://arxiv.org/abs/2303.08720v1 |
Light weakly interacting particles could be copiously produced in the Sun
which, as a well-understood star, could provide severe constraints on such new
physics. In this work, we calculate the solar production rates of light gauge
bosons (e.g. dark photon) arising from various $U(1)$ extensions of the
standard model. I... | http://arxiv.org/abs/2304.12907v2 |
Recently, a Dirac exceptional point (EP) was reported in a non-Hermitian
system. Unlike a Dirac point in Hermitian systems, this Dirac EP has coalesced
eigenstates in addition to the degenerate energy. Also different from a typical
EP, the two energy levels connected at this Dirac EP remain real in its
vicinity and dis... | http://arxiv.org/abs/2303.07413v1 |
We show that the mean curvature flow of a generic closed surface in
$\mathbb{R}^3$ avoids multiplicity one tangent flows that are not round
spheres/cylinders. In particular, we show that any non-cylindrical
self-shrinker with a cylindrical end cannot arise generically. | http://arxiv.org/abs/2302.08409v1 |
Graphs are a natural representation of brain activity derived from functional
magnetic imaging (fMRI) data. It is well known that clusters of anatomical
brain regions, known as functional connectivity networks (FCNs), encode
temporal relationships which can serve as useful biomarkers for understanding
brain function an... | http://arxiv.org/abs/2301.11408v1 |
General classical arguments on the time evolution of the phase-space density
can be used to derive constraints on the mass of particle candidates for the
cosmological dark matter (DM). The resulting Tremaine-Gunn limit is extremely
useful in constraining particle DM models. In certain models, however, the DM
particle m... | http://arxiv.org/abs/2302.10246v2 |
We highlight the role of weak lensing measurements from current and upcoming
stage-IV imaging surveys in the search for cosmic inflation, specifically in
measuring the scalar spectral index $n_s$. To do so, we combine the Dark Energy
Survey 3 years of observation weak lensing and clustering data with BICEP/Keck,
Planck... | http://arxiv.org/abs/2310.10731v1 |
Lexical simplification (LS) methods based on pretrained language models have
made remarkable progress, generating potential substitutes for a complex word
through analysis of its contextual surroundings. However, these methods require
separate pretrained models for different languages and disregard the
preservation of ... | http://arxiv.org/abs/2307.15286v1 |
In ``Distributed quantum sensing with mode-entangled spin-squeezed atomic
states" Nature (2022), Malia et. al. claim to improve the precision of a
network of clocks by using entanglement. In particular, by entangling a clock
network with up to four nodes, a precision 11.6 dB better than the quantum
projection noise lim... | http://arxiv.org/abs/2302.00733v2 |
A Manhattan world lying along cuboid buildings is useful for camera angle
estimation. However, accurate and robust angle estimation from fisheye images
in the Manhattan world has remained an open challenge because general scene
images tend to lack constraints such as lines, arcs, and vanishing points. To
achieve higher... | http://arxiv.org/abs/2303.17166v3 |
The Sinkhorn algorithm is a widely used method for solving the optimal
transport problem, and the Greenkhorn algorithm is one of its variants. While
there are modified versions of these two algorithms whose computational
complexities are $O({n^2\|C\|_\infty^2\log n}/{\varepsilon^2})$ to achieve an
$\varepsilon$-accurac... | http://arxiv.org/abs/2305.14939v2 |
