A purported `AI Singularity' has been in the public eye recently. Mass media
and US national political attention focused on `AI Doom' narratives hawked by
social media influencers. The European Commission is announcing initiatives to
forestall `AI Extinction'. In my opinion, `AI Singularity' is the wrong
narrative for ... | http://arxiv.org/abs/2310.00865v1 |
Motivated by the Farrell-Jones Conjecture for group rings, we formulate the
$\mathcal{C}$op-Farrell-Jones Conjecture for the K-theory of Hecke algebras of
td-groups. We prove this conjecture for (closed subgroups of) reductive p-adic
groups G. In particular, the projective class group $K_0(\mathcal{H}(G))$ for a
(close... | http://arxiv.org/abs/2306.03452v2 |
We propose an academic publishing system where research papers are stored in
a network of data centres owned by university libraries and research
institutions, and are interfaced with the academic community through a website.
In our system, the editor is replaced by an initial adjusted community-wide
evaluation, the st... | http://arxiv.org/abs/2304.12326v1 |
Decentralized multi-agent reinforcement learning (MARL) algorithms have
become popular in the literature since it allows heterogeneous agents to have
their own reward functions as opposed to canonical multi-agent Markov Decision
Process (MDP) settings which assume common reward functions over all agents. In
this work, ... | http://arxiv.org/abs/2305.05573v2 |
We investigate the fluctuations of the net-baryon number density in dense
hadronic matter. Chiral dynamics is modeled via the parity doublet Lagrangian,
and the mean-field approximation is employed to account for chiral criticality.
We focus on the qualitative properties and systematics of the second-order
susceptibili... | http://arxiv.org/abs/2301.09866v2 |
This paper defines two decreasing measures for terms of the simply typed
lambda-calculus, called the W-measure and the Tm-measure. A decreasing measure
is a function that maps each typable lambda-term to an element of a
well-founded ordering, in such a way that contracting any beta-redex decreases
the value of the func... | http://arxiv.org/abs/2304.12440v2 |
Application of neural networks in industrial settings, such as automated
factories with bin-picking solutions requires costly production of large
labeled data-sets. This paper presents an automatic data generation tool with a
procedural model of a cardboard box. We briefly demonstrate the capabilities of
the system, it... | http://arxiv.org/abs/2305.05215v2 |
Digital twin technology has is anticipated to transform healthcare, enabling
personalized medicines and support, earlier diagnoses, simulated treatment
outcomes, and optimized surgical plans. Digital twins are readily gaining
traction in industries like manufacturing, supply chain logistics, and civil
infrastructure. N... | http://arxiv.org/abs/2307.04772v1 |
Machine-readable representations of privacy policies are door openers for a
broad variety of novel privacy-enhancing and, in particular,
transparency-enhancing technologies (TETs). In order to generate such
representations, transparency information needs to be extracted from written
privacy policies. However, respectiv... | http://arxiv.org/abs/2305.15006v2 |
By integrating certain optimization solvers with deep neural networks, deep
unfolding network (DUN) with good interpretability and high performance has
attracted growing attention in compressive sensing (CS). However, existing DUNs
often improve the visual quality at the price of a large number of parameters
and have t... | http://arxiv.org/abs/2304.13986v1 |
Synchronization of two replicas of coupled map lattices for continuous maps
is known to be in the multiplicative noise universality class. We study this
transition in the presence of quenched disorder in coupling. The disorder is
identical in both replicas. We study one-dimensional, two-dimensional, and
globally couple... | http://arxiv.org/abs/2308.12795v2 |
Rendering scenes observed in a monocular video from novel viewpoints is a
challenging problem. For static scenes the community has studied both
scene-specific optimization techniques, which optimize on every test scene, and
generalized techniques, which only run a deep net forward pass on a test scene.
In contrast, for... | http://arxiv.org/abs/2310.08587v3 |
