Neural Density-Distance Fields

1 code implementation29 Jul 2022 Itsuki Ueda, Yoshihiro Fukuhara, Hirokatsu Kataoka, Hiroaki Aizawa, Hidehiko Shishido, Itaru Kitahara

However, it is difficult to achieve high localization performance by only density fields-based methods such as Neural Radiance Field (NeRF) since they do not provide density gradient in most empty regions.

RLTutor: Reinforcement Learning Based Adaptive Tutoring System by Modeling Virtual Student with Fewer Interactions

1 code implementation31 Jul 2021 Yoshiki Kubotani, Yoshihiro Fukuhara, Shigeo Morishima

However, optimization using reinforcement learning requires a large number of interactions, and thus it cannot be applied directly to actual students.

Enhancing Inverse Problem Solutions with Accurate Surrogate Simulators and Promising Candidates

1 code implementation26 Apr 2023 Akihiro Fujii, Hideki Tsunashima, Yoshihiro Fukuhara, Koji Shimizu, Satoshi Watanabe

In this study, we investigated the impact of surrogate simulators' accuracy on the solutions and discovered that the more accurate the surrogate simulator is, the better the solutions become.

Understanding Fake Faces

no code implementations22 Sep 2018 Ryota Natsume, Kazuki Inoue, Yoshihiro Fukuhara, Shintaro Yamamoto, Shigeo Morishima, Hirokatsu Kataoka

Face recognition research is one of the most active topics in computer vision (CV), and deep neural networks (DNN) are now filling the gap between human-level and computer-driven performance levels in face verification algorithms.

ATRO: Adversarial Training with a Rejection Option

no code implementations24 Oct 2020 Masahiro Kato, Zhenghang Cui, Yoshihiro Fukuhara

In this paper, in order to acquire a more reliable classifier against adversarial attacks, we propose the method of Adversarial Training with a Rejection Option (ATRO).

Learning with Protection: Rejection of Suspicious Samples under Adversarial Environment

no code implementations25 Sep 2019 Masahiro Kato, Yoshihiro Fukuhara, Hirokatsu Kataoka, Shigeo Morishima

Our main idea is to apply a framework of learning with rejection and adversarial examples to assist in the decision making for such suspicious samples.
