The Origins and Prevalence of Texture Bias in Convolutional Neural Networks

2019 · arXiv (Cornell University)

Recent work has indicated that, unlike humans, ImageNet-trained CNNs tend to classify images by texture rather than by shape. How pervasive is this bias, and where does it come from? We find that, when trained …

Big Self-Supervised Models Advance Medical Image Classification

2021 · arXiv (Cornell University)

Self-supervised pretraining followed by supervised fine-tuning has seen success in image recognition, especially when labeled examples are scarce, but has received limited attention in medical image analysis. This paper studies the effectiveness of self-supervised learning …
