Abstract

In this work, we studied the catastrophic forgetting effect in transfer learning for the development of a deep learning model to perform COVID-19 pneumonia classification using chest x-ray radiographs. We demonstrated vendor differences using a large multi-vendor chest x-ray dataset for COVID-19 classification and investigated its impact on the generalizability of the model. We showed that the model trained from one particular vendor may not generalize well to other vendors. While both vendor-based fine-tuning and joint training can improve the performance on the new vendor test set, the first approach may cause performance degradation on the previous vendor test set.
