Individual preference (IP) stability, introduced by Ahmadi et al. (ICML
2022), is a natural clustering objective inspired by stability and fairness
constraints. A clustering is $\alpha$-IP stable if the average distance of
every data point to its own cluster is at most $\alpha$ times the average
distance to any other c... | http://arxiv.org/abs/2309.16840v1 |
The $\sim 5\sigma$ mismatch between the value of the Hubble parameter
measured by SH0ES and the one inferred from the inverse distance ladder (IDL)
constitutes the biggest tension afflicting the standard model of cosmology,
which could be pointing to the need of physics beyond $\Lambda$CDM. In this
paper we study the b... | http://arxiv.org/abs/2309.07795v2 |
Heterogeneous federated multi-task learning (HFMTL) is a federated learning
technique that combines heterogeneous tasks of different clients to achieve
more accurate, comprehensive predictions. In real-world applications, visual
and natural language tasks typically require large-scale models to extract
high-level abstr... | http://arxiv.org/abs/2306.17465v1 |
Understanding and adequately assessing the difference between a true and a
learnt causal graphs is crucial for causal inference under interventions. As an
extension to the graph-based structural Hamming distance and structural
intervention distance, we propose a novel continuous-measured metric that
considers the under... | http://arxiv.org/abs/2307.16452v1 |
Motion planning for autonomous robots in tight, interaction-rich, and mixed
human-robot environments is challenging. State-of-the-art methods typically
separate prediction and planning, predicting other agents' trajectories first
and then planning the ego agent's motion in the remaining free space. However,
agents' lac... | http://arxiv.org/abs/2309.14931v2 |
Atmospheric temperatures are to be estimated from thermal emission spectra of
Earth-like exoplanets orbiting M-stars as observed by current and future
planned missions. To this end, a line-by-line radiative transfer code is used
to generate synthetic thermal infrared (TIR) observations. The range of
'observed' intensit... | http://arxiv.org/abs/2306.00131v1 |
The ongoing modernization of the power system, involving new equipment
installations and upgrades, exposes the power system to the introduction of
malware into its operation through supply chain attacks. Supply chain attacks
present a significant threat to power systems, allowing cybercriminals to
bypass network defens... | http://arxiv.org/abs/2309.05814v1 |
The first law of thermodynamics restates the law of conservation of energy.
It partitions the change in energy of a system into two pieces, heat and work.
While there is no ambiguity to define heat and work in classical
thermodynamics, their classification in the quantum regime is not that obvious.
Thus, the first law ... | http://arxiv.org/abs/2301.00196v2 |
Let $\mathbb{A}=\{z: r< |z|<R\}$ and $\A^\ast=\{z: r^\ast<|z|<R^\ast\}$ be
annuli in the complex plane. Let $p\in[1,2]$ and assume that
$\mathcal{H}^{1,p}(\A,\A^*)$ is the class of Sobolev homeomorphisms between
$\A$ and $\A^*$, $h:\A\onto \A^*$. Then we consider the following Dirichlet
type energy of $h$: $$\mathcal{F... | http://arxiv.org/abs/2303.00089v2 |
Climate change mitigation in urban mobility requires policies reconfiguring
urban form to increase accessibility and facilitate low-carbon modes of
transport. However, current policy research has insufficiently assessed urban
form effects on car travel at three levels: (1) Causality -- Can causality be
established beyo... | http://arxiv.org/abs/2308.16599v2 |
A Lorenz hull is the convex hull of the range of an $n$-dimensional vector of
finite signed measures defined on a common measurable space. We show that the
set of $n$-dimensional Lorenz hulls is endowed with a natural product that is
commutative, associative, and distributive over Minkowski sums. The same holds
with "z... | http://arxiv.org/abs/2309.09790v1 |
DyRu2Si2 is a frustrated magnet to exhibit multiple magnetic phase transition
in zero and finite magnetic fields. We investigated and characterized the phase
transition between the partially-ordered antiferromagnetic phases at zero field
by ac susceptibility measurements. Detailed ac susceptibility measurements
