Quadratic computations maintain neural specificity to natural stimuli across stages of visual processing

Kavli Affiliate: Tatyana Sharpee | Authors: Ryan J. Rowekamp and Tatyana Sharpee | Summary: Abstract Despite recent successes in machine vision, artificial recognition systems continue to be less robust than biological systems. The brittleness of artificial recognition system has been attributed to the linearity of the core operation that matches inputs to target patterns at […]

Radiation from Global Topological Strings using Adaptive Mesh Refinement: Massive Modes

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Amelia Drew, E. P. S. Shellard, , , | Summary: We implement adaptive mesh refinement (AMR) simulations of global topological strings using the public code, GRChombo. We perform a quantitative investigation of massive radiation from single sinusoidally displaced string configurations, studying a range of string […]
