Medical Vision Language Pretraining: A survey

no code implementations11 Dec 2023 Prashant Shrestha, Sanskar Amgain, Bidur Khanal, Cristian A. Linte, Binod Bhattarai

Medical Vision Language Pretraining (VLP) has recently emerged as a promising solution to the scarcity of labeled data in the medical domain.

Improving Medical Image Classification in Noisy Labels Using Only Self-supervised Pretraining

1 code implementation8 Aug 2023 Bidur Khanal, Binod Bhattarai, Bishesh Khanal, Cristian A. Linte

In this work, we explore contrastive and pretext task-based self-supervised pretraining to initialize the weights of a deep learning classification model for two medical datasets with self-induced noisy labels -- NCT-CRC-HE-100K tissue histological images and COVID-QU-Ex chest X-ray images.

How Does Heterogeneous Label Noise Impact Generalization in Neural Nets?

no code implementations29 Jun 2021 Bidur Khanal, Christopher Kanan

Incorrectly labeled examples, or label noise, is common in real-world computer vision datasets.

Label Geometry Aware Discriminator for Conditional Generative Networks

no code implementations12 May 2021 Suman Sapkota, Bidur Khanal, Binod Bhattarai, Bishesh Khanal, Tae-Kyun Kim

Multi-domain image-to-image translation with conditional Generative Adversarial Networks (GANs) can generate highly photo realistic images with desired target classes, yet these synthetic images have not always been helpful to improve downstream supervised tasks such as image classification.
