Structured Gaussian Processes for Uncertainty-Aware Classification of High-Dimensional, Small-Sampled Omics Data
Yue Zhang, Nandini Amit Gadhia, Georgios Karagiannis +1
Classifying heterogeneous omics data remains a fundamental challenge in computational biology, particularly in high-dimensional, small-sample settings where nonlinear interactions…
Duality, generalized global symmetries and jet space isometries
Athanasios Chatzistavrakidis, Georgios Karagiannis, Arash Ranjbar
We revisit universal features of duality in linear and nonlinear relativistic scalar and Abelian 1-form theories with single or multiple fields, which exhibit ordinary or generaliz…
Axion gravitodynamics, Lense-Thirring effect, and gravitational waves
Athanasios Chatzistavrakidis, Georgios Karagiannis, George Manolakos +1
We investigate physical implications of a gravitational analog of axion electrodynamics with a parity-violating gravitoelectromagnetic theta term. This is related to the Nieh-Yan t…
Tensor Galileons as Lovelock theories
Georgios Karagiannis
We review the construction of Galileon interactions involving a single two-column mixed-symmetry tensor of arbitrary degree in flat spacetime of arbitrary dimensions, in a reverse…
Duality and higher Buscher rules in p-form gauge theory and linearized gravity
Athanasios Chatzistavrakidis, Georgios Karagiannis, Arash Ranjbar
We perform an in-depth analysis of the transformation rules under duality for couplings of theories containing multiple scalars, -form gauge fields, linearized gravitons or $(p,…
Accelerating Convergence of Replica Exchange Stochastic Gradient MCMC via Variance Reduction
Wei Deng, Qi Feng, Georgios Karagiannis +2
Replica exchange stochastic gradient Langevin dynamics (reSGLD) has shown promise in accelerating the convergence in non-convex learning; however, an excessively large correction f…
