through causal modeling with a directed acyclic graph (DAG) on the
decision-distribution interplay, we investigate the possibility of achieving
long-term fairness from a dynamic pe... | http://arxiv.org/abs/2301.08987v3 |
Humans tend to follow the Uniform Information Density (UID) principle by
distributing information evenly in utterances. We study if decoding algorithms
implicitly follow this UID principle, and under what conditions adherence to
UID might be desirable for dialogue generation. We generate responses using
different decod... | http://arxiv.org/abs/2303.17006v1 |
Recently Gubbiotti, Joshi, Tran and Viallet classified birational maps in
four dimensions admitting two invariants (first integrals) with a particular
degree structure, by considering recurrences of fourth order with a certain
symmetry. The last three of the maps so obtained were shown to be Liouville
integrable, in th... | http://arxiv.org/abs/2309.02336v3 |
Detecting thermal Unruh radiation from accelerated electrons has presented a
formidable challenge due not only to technical difficulties but also for lack
of conceptual clarity about what is actually seen by a laboratory observer. We
give a summary of the current interpretations along with a simpler heuristic
descripti... | http://arxiv.org/abs/2301.06772v5 |
We study boundaries arising from limits of ratios of transition probabilities
for random walks on relatively hyperbolic groups. We extend, as well as
determine significant limitations of, a strategy employed by Woess for
computing ratio-limit boundaries for the class of hyperbolic groups. On the one
hand we employ resu... | http://arxiv.org/abs/2303.10769v4 |
With synchronization being one of nature's most ubiquitous collective
behaviors, the field of network synchronization has experienced tremendous
growth, leading to significant theoretical developments. However, most of these
previous studies consider uniform connection weights and undirected networks
with positive coup... | http://arxiv.org/abs/2303.08126v1 |
Liquid crystal elastomers (LCEs) are soft phase-changing solids that exhibit
large reversible contractions upon heating, Goldstone-like soft modes and
resultant microstructural instabilities. We heat a planar LCE slab to
isotropic, clamp the lower surface then cool back to nematic. Clamping prevents
macroscopic elongat... | http://arxiv.org/abs/2303.07215v3 |
We present the design, implementation, and evaluation of MiFly, a
self-localization system for autonomous drones that works across indoor and
outdoor environments, including low-visibility, dark, and GPS-denied settings.
MiFly performs 6DoF self-localization by leveraging a single millimeter-wave
(mmWave) anchor in its... | http://arxiv.org/abs/2310.08778v1 |
Searches for long-lived particles (LLPs) are among the most promising avenues
for discovering physics beyond the Standard Model at the Large Hadron Collider
(LHC). However, displaced signatures are notoriously difficult to identify due
to their ability to evade standard object reconstruction strategies. In
particular, ... | http://arxiv.org/abs/2304.12867v2 |
As Deep Neural Networks (DNNs) are rapidly being adopted within large
software systems, software developers are increasingly required to design,
train, and deploy such models into the systems they develop. Consequently,
testing and improving the robustness of these models have received a lot of
attention lately. Howeve... | http://arxiv.org/abs/2301.11568v1 |
This paper compares and explores the performance of both mobile device camera
and laptop camera as convenient tool for capturing images for non-invasive
detection of Diabetes Mellitus (DM) using facial block texture features.
Participants within age bracket 20 to 79 years old were chosen for the dataset.
12mp and 7mp m... | http://arxiv.org/abs/2307.15480v1 |
Unsupervised out-of-distribution detection (OOD) seeks to identify
out-of-domain data by learning only from unlabeled in-domain data. We present a
novel approach for this task - Lift, Map, Detect (LMD) - that leverages recent
advancement in diffusion models. Diffusion models are one type of generative
models. At their ... | http://arxiv.org/abs/2302.10326v2 |
In recent experimental and theoretical studies of graphene, disorder
scattering processes have been suggested to play an important role in its
electronic and transport properties. In the preceding paper, it has been shown
that the nonperturbative momentum-space Lanczos method is able to accurately
describe all the mult... | http://arxiv.org/abs/2308.02779v1 |
