Testing the Channels of Convolutional Neural Networks

no code implementations6 Mar 2023 Kang Choi, Donghyun Son, Younghoon Kim, Jiwon Seo

To understand and debug convolutional neural networks (CNNs) we propose techniques for testing the channels of CNNs.

Multiple Instance Neural Networks Based on Sparse Attention for Cancer Detection using T-cell Receptor Sequences

no code implementations9 Aug 2022 Younghoon Kim, Tao Wang, Danyi Xiong, Xinlei Wang, Seongoh Park

Among different types of data used to answer this biological question, studies based on T cell receptors (TCRs) are under recent spotlight due to the growing appreciation of the roles of the host immunity system in tumor biology.

GMAC: A Distributional Perspective on Actor-Critic Framework

no code implementations24 May 2021 Daniel Wontae Nam, Younghoon Kim, Chan Y. Park

In this paper, we devise a distributional framework on actor-critic as a solution to distributional instability, action type restriction, and conflation between samples and statistics.

A Distributional Perspective on Actor-Critic Framework

no code implementations1 Jan 2021 Daniel Wontae Nam, Younghoon Kim, Chan Youn Park

Recent distributional reinforcement learning methods, despite their successes, still contain fundamental problems that can lead to inaccurate representations of value distributions, such as distributional instability, action type restriction, and biased approximation.
