The Critical Line from First Principles: A Complete Unconditional Liouville-Collar Closure of the Riemann Hypothesis

Deep Bhattacharjee

9-54

Let X be a smooth complex projective variety and let Hdg?(X) = H²?(X, ?) ? H?,?(X, ?) denote the space of rational Hodge classes of codimension p. This paper formulates the zero-d...

Breakdown Point Analysis for Deep Neural Network Estimators Under Heavy-Tailed Noise

Abdullah Mohammed Rashid; Hadeel Fawzi Mohammed; Hasan Talib Hendi

106-127

In this paper, we experimentally assess the breakdown point of deep neural network regression estimators trained in the presence of heavy-tailed label contamination. On the standar...
