C-SENN: Contrastive Self-Explaining Neural Network

no code implementations20 Jun 2022 Yoshihide Sawada, Keigo Nakamura

In this study, we use a self-explaining neural network (SENN), which learns unsupervised concepts, to acquire concepts that are easy for people to understand automatically.

Concept Bottleneck Model with Additional Unsupervised Concepts

1 code implementation3 Feb 2022 Yoshihide Sawada, Keigo Nakamura

We refer to the proposed model as the concept bottleneck model with additional unsupervised concepts (CBM-AUC).

Deep learning-based topological optimization for representing a user-specified design area

no code implementations11 Apr 2020 Keigo Nakamura, Yoshiro Suzuki

In this study, we propose a new deep learning model to generate an optimized structure for a given design domain and other boundary conditions without iteration.
