Distributionally Robust Safe Screening

no code implementations25 Apr 2024 Hiroyuki Hanada, Satoshi Akahane, Tatsuya Aoyama, Tomonari Tanaka, Yoshito Okura, Yu Inatsu, Noriaki Hashimoto, Taro Murayama, Lee Hanju, Shinya Kojima, Ichiro Takeuchi

In this study, we propose a method Distributionally Robust Safe Screening (DRSS), for identifying unnecessary samples and features within a DR covariate shift setting.

Mixing Histopathology Prototypes into Robust Slide-Level Representations for Cancer Subtyping

1 code implementation19 Oct 2023 Joshua Butke, Noriaki Hashimoto, Ichiro Takeuchi, Hiroaki Miyoshi, Koichi Ohshima, Jun Sakuma

Whole-slide image analysis via the means of computational pathology often relies on processing tessellated gigapixel images with only slide-level labels available.

Generalized Low-Rank Update: Model Parameter Bounds for Low-Rank Training Data Modifications

no code implementations22 Jun 2023 Hiroyuki Hanada, Noriaki Hashimoto, Kouichi Taji, Ichiro Takeuchi

Among the class of ML methods known as linear estimators, there exists an efficient model update framework called the low-rank update that can effectively handle changes in a small number of rows and columns within the data matrix.

Transformer-based Personalized Attention Mechanism for Medical Images with Clinical Records

1 code implementation7 Jun 2022 Yusuke Takagi, Noriaki Hashimoto, Hiroki Masuda, Hiroaki Miyoshi, Koichi Ohshima, Hidekata Hontani, Ichiro Takeuchi

In medical image diagnosis, identifying the attention region, i. e., the region of interest for which the diagnosis is made, is an important task.

Computing Valid p-values for Image Segmentation by Selective Inference

no code implementations CVPR 2020 Kosuke Tanizaki, Noriaki Hashimoto, Yu Inatsu, Hidekata Hontani, Ichiro Takeuchi

To overcome this difficulty, we introduce a statistical approach called selective inference, and develop a framework to compute valid p-values in which the segmentation bias is properly accounted for.
