Neural Collapse in Cumulative Link Models for Ordinal Regression: An Analysis with Unconstrained Feature Model

Chuang Ma, Tomoyuki Obuchi, Toshiyuki Tanaka

A phenomenon known as ''Neural Collapse (NC)'' in deep classification tasks, in which the penultimate-layer features and the final classifiers exhibit an extremely simple geometric…

Universality of reservoir systems with recurrent neural networks

Hiroki Yasumoto, Toshiyuki Tanaka

Approximation capability of reservoir systems whose reservoir is a recurrent neural network (RNN) is discussed. We show what we call uniform strong universality of RNN reservoir sy…

Convergence Analysis of Mean Shift

Ryoya Yamasaki, Toshiyuki Tanaka

The mean shift (MS) algorithm seeks a mode of the kernel density estimate (KDE). This study presents a convergence guarantee of the mode estimate sequence generated by the MS algor…
