Statistical Test for Generated Hypotheses by Diffusion Models

no code implementations19 Feb 2024 Teruyuki Katsuoka, Tomohiro Shiraishi, Daiki Miwa, Vo Nguyen Le Duy, Ichiro Takeuchi

In this study, we consider a medical diagnostic task using generated images by diffusion models, and propose a statistical test to quantify its reliability.

Statistical Test for Attention Map in Vision Transformer

1 code implementation16 Jan 2024 Tomohiro Shiraishi, Daiki Miwa, Teruyuki Katsuoka, Vo Nguyen Le Duy, Kouichi Taji, Ichiro Takeuchi

In this study, we propose a statistical test for ViT's attentions, enabling us to use the attentions as reliable quantitative evidence indicators for ViT's decision-making with a rigorously controlled error rate.

Selective Inference for Changepoint detection by Recurrent Neural Network

1 code implementation25 Nov 2023 Tomohiro Shiraishi, Daiki Miwa, Vo Nguyen Le Duy, Ichiro Takeuchi

In this study, we investigate the quantification of the statistical reliability of detected change points (CPs) in time series using a Recurrent Neural Network (RNN).
