Nonlinear social evolution and the emergence of collective action
February 28, 2023

Quantitative Biology
Populations and Evolution
Organisms from microbes to humans engage in a variety of social behaviors,
which affect fitness in complex, often nonlinear ways. The question of how
these behaviors evolve has consequences ranging from antibiotic resistance to
human origin...
Disentangling Structural Breaks in Factor Models for Macroeconomic Data

Through a routine normalization of the factor variance, standard methods for
estimating factor models in macroeconomics do not distinguish between breaks of
the factor variance and factor loadings. We argue that it is important to
distingui...
On the Duality of Teleportation and Dense Coding

Quantum Physics
Quantum teleportation is a quantum communication primitive that allows a
long-distance quantum channel to be built using pre-shared entanglement and
one-way classical communication. However, the quality of the established
channel crucially ...

Markov Decision Process (MDP) presents a mathematical framework to formulate
the learning processes of agents in reinforcement learning. MDP is limited by
the Markovian assumption that a reward only depends on the immediate state and
action...
Efficient Masked Autoencoders with Self-Consistency

Computer Science
Computer Vision and Pattern Recognition
Inspired by the masked language modeling (MLM) in natural language processing
tasks, the masked image modeling (MIM) has been recognized as a strong
self-supervised pre-training method in computer vision. However, the high
random mask ratio...
Full large deviation principles for the largest eigenvalue of
sub-Gaussian Wigner matrices
February 28, 2023

Mathematics
Probability
We establish precise upper-tail asymptotics and large deviation principles
for the rightmost eigenvalue λ1 of Wigner matrices with sub-Gaussian
entries. In contrast to the case of heavier tails, where deviations of
λ1 are ...
Computational expressivity of (circular) proofs with fixed points

Computer Science
Logic in Computer Science
We study the computational expressivity of proof systems with fixed point
operators, within the `proofs-as-programs' paradigm. We start with a calculus
μLJ (due to Clairambault) that extends intuitionistic logic by
least and gr...
Flexible nuclear power and fluctuating renewables? -- A techno-economic

Many governments are considering constructing new nuclear power plants to
support the decarbonization of the energy system. On the one hand, dispatchable
nuclear plants can complement fluctuating generation from wind and PV. On the
other ha...

We extend the well-known Dumont-Thomas numeration systems to Z
using an approach inspired by the two's complement numeration system. Integers
in Z are canonically represented by a finite word (starting with
$\mathtt{0}...
Estimation-of-Distribution Algorithms for Multi-Valued Decision

Computer Science
Neural and Evolutionary Computing
The majority of research on estimation-of-distribution algorithms (EDAs)
concentrates on pseudo-Boolean optimization and permutation problems, leaving
the domain of EDAs for problems in which the decision variables can take more
