Nonparametric logistic regression with deep learning

no code implementations23 Jan 2024 Atsutomo Yara, Yoshikazu Terada

In the logistic regression, we usually consider the maximum likelihood estimator, and the excess risk is the expectation of the Kullback-Leibler (KL) divergence between the true and estimated conditional class probabilities.

Convex Clustering through MM: An Efficient Algorithm to Perform Hierarchical Clustering

3 code implementations3 Nov 2022 Daniel J. W. Touw, Patrick J. F. Groenen, Yoshikazu Terada

Convex clustering is a modern method with both hierarchical and $k$-means clustering characteristics.

More Powerful Selective Kernel Tests for Feature Selection

1 code implementation14 Oct 2019 Jen Ning Lim, Makoto Yamada, Wittawat Jitkrittum, Yoshikazu Terada, Shigeyuki Matsui, Hidetoshi Shimodaira

An approach for addressing this is via conditioning on the selection procedure to account for how we have used the data to generate our hypotheses, and prevent information to be used again after selection.

Fast generalization error bound of deep learning without scale invariance of activation functions

no code implementations25 Jul 2019 Yoshikazu Terada, Ryoma Hirose

In this paper, using the framework for analyzing the generalization error developed in Suzuki (2018), we derive a fast learning rate for deep neural networks with more general activation functions.

Clustering for high-dimension, low-sample size data using distance vectors

no code implementations12 Dec 2013 Yoshikazu Terada

In high-dimension, low-sample size (HDLSS) data, it is not always true that closeness of two objects reflects a hidden cluster structure.
