Fluctuation theorems and exact multi-allele fixation probabilities
Emil A. Yuzbashyan, Alexander Feigel, Alexandre V. Morozov
A mutant gene that appears in a finite population will, in the long run, either disappear from it or become fixed, so that all members of the population will carry a copy of the mu…
Attention as In-Context Empirical Bayes: A Two-Stage View via Particle Dynamics
Matthew Smart, Soumya Ganguly, Nilava Metya +2
We study minimal attention-only transformers under all-token corruption and show they admit a two-stage empirical Bayes interpretation. A single attention step computes a kernel-we…
Coarse-grained Shannon entropy of random walks with shrinking steps
Alexander Feigel, Alexandre V. Morozov
In one-dimensional diffusive processes with discrete steps characterized by geometrically decaying magnitudes, the usual Gaussian broadening familiar from Brownian motion is replac…
Network community detection and clustering with random walks
Aditya Ballal, Willow B. Kion-Crosby, Alexandre V. Morozov
We present a novel approach to partitioning network nodes into non-overlapping communities - a key step in revealing network modularity and hierarchical organization. Our methodolo…
Model selection and signal extraction using Gaussian Process regression
Abhijith Gandrakota, Amitabh Lath, Alexandre V. Morozov +1
We present a novel computational approach for extracting weak signals, whose exact location and width may be unknown, from complex background distributions with an arbitrary functi…
Optical valleytronics of impurity states in two-dimensional Dirac materials
Dogyun Ko, A. V. Morozov, V. M. Kovalev +1
We analyze the valley selection rules for optical transitions from impurity states to the conduction band in two-dimensional Dirac materials, taking a monolayer of MoS2 as an examp…
