Improved Multimodal Fusion for Small Datasets with Auxiliary Supervision

no code implementations1 Apr 2023 Gregory Holste, Douwe van der Wal, Hans Pinckaers, Rikiya Yamashita, Akinori Mitani, Andre Esteva

We validate the proposed approaches on prostate cancer diagnosis from paired histopathology imaging and tabular clinical features.

Contrastive learning-based pretraining improves representation and transferability of diabetic retinopathy classification models

no code implementations24 Aug 2022 Minhaj Nur Alam, Rikiya Yamashita, Vignav Ramesh, Tejas Prabhune, Jennifer I. Lim, R. V. P. Chan, Joelle Hallak, Theodore Leng, Daniel Rubin

CL based pretraining with NST significantly improves DL classification performance, helps the model generalize well (transferable from EyePACS to UIC data), and allows training with small, annotated datasets, therefore reducing ground truth annotation burden of the clinicians.

Contrastive Learning Style Transfer

Learning domain-agnostic visual representation for computational pathology using medically-irrelevant style transfer augmentation

1 code implementation2 Feb 2021 Rikiya Yamashita, Jin Long, Snikitha Banda, Jeanne Shen, Daniel L. Rubin

Although various methods such as domain adaptation and domain generalization have evolved to combat this challenge, learning robust and generalizable representations is core to medical image understanding, and continues to be a problem.

Data Valuation for Medical Imaging Using Shapley Value: Application on A Large-scale Chest X-ray Dataset

no code implementations15 Oct 2020 Siyi Tang, Amirata Ghorbani, Rikiya Yamashita, Sameer Rehman, Jared A. Dunnmon, James Zou, Daniel L. Rubin

In this study, we used data Shapley, a data valuation metric, to quantify the value of training data to the performance of a pneumonia detection algorithm in a large chest X-ray dataset.

Analysis Of Multi Field Of View Cnn And Attention Cnn On H&E Stained Whole-slide Images On Hepatocellular Carcinoma

no code implementations12 Feb 2020 Mehmet Burak Sayıcı, Rikiya Yamashita, Jeanne Shen

Determination of the tile size affects the performance of the algorithms since small field of view can not capture the information on a larger scale and large field of view can not capture the information on a cellular scale.
