Improving Shift Invariance in Convolutional Neural Networks with Translation Invariant Polyphase Sampling

no code implementations11 Apr 2024 Sourajit Saha, Tejas Gokhale

Downsampling operators break the shift invariance of convolutional neural networks (CNNs) and this affects the robustness of features learned by CNNs when dealing with even small pixel-level shift.

SeeBel: Seeing is Believing

1 code implementation18 Dec 2023 Sourajit Saha, Shubhashis Roy Dipta

While the significance of discovering and introspecting the correlation between dataset statistics and AI model performance for dense prediction computer vision tasks such as semantic segmentation is well established in the computer vision literature, to the best of our knowledge, no visualization tools have been proposed to view and analyze the aforementioned tasks.

Mitigating domain shift in AI-based tuberculosis screening with unsupervised domain adaptation

no code implementations9 Nov 2021 Nishanjan Ravin, Sourajit Saha, Alan Schweitzer, Ameena Elahi, Farouk Dako, Daniel Mollura, David Chapman

We show that without domain adaptation, ResNet-50 has difficulty in generalizing between imaging distributions from a number of public Tuberculosis screening datasets with imagery from geographically distributed regions.
