Augmenting Chest X-ray Datasets with Non-Expert Annotations

no code implementations5 Sep 2023 Cathrine Damgaard, Trine Naja Eriksen, Dovile Juodelyte, Veronika Cheplygina, Amelia Jiménez-Sánchez

We train a chest drain detector with the non-expert annotations that generalizes well to expert labels.

Revisiting Hidden Representations in Transfer Learning for Medical Imaging

1 code implementation16 Feb 2023 Dovile Juodelyte, Amelia Jiménez-Sánchez, Veronika Cheplygina

Our findings show that the similarity between networks before and after fine-tuning does not correlate with performance gains, suggesting that the advantages of transfer learning might not solely originate from the reuse of features in the early layers of a convolutional neural network.
