Classification of Hematoma: Joint Learning of Semantic Segmentation and Classification

no code implementations31 Mar 2021 Hokuto Hirano, Tsuyoshi Okita

Cerebral hematoma grows rapidly in 6-24 hours and misprediction of the growth can be fatal if it is not operated by a brain surgeon.

Vulnerability of deep neural networks for detecting COVID-19 cases from chest X-ray images to universal adversarial attacks

1 code implementation22 May 2020 Hokuto Hirano, Kazuki Koga, Kazuhiro Takemoto

As an example, we show that iterative fine-tuning of the DNN models using UAPs improves the robustness of the DNN models against UAPs.

Simple iterative method for generating targeted universal adversarial perturbations

1 code implementation15 Nov 2019 Hokuto Hirano, Kazuhiro Takemoto

Our method combines the simple iterative method for generating non-targeted UAPs and the fast gradient sign method for generating a targeted adversarial perturbation for an input.
