From: Biased data, biased AI: deep networks predict the acquisition site of TCGA images
Comparison of acquisition site detection for deep features obtained from DenseNet (trained on nonmedical data), KimiaNet I (finetuned for cancer subtype classification), and KimiaNet IV (fully-trained for cancer subtype classification). The average acquisition site classification accuracy of DenseNet, KimiaNet I, and KimiaNet IV were 0.65, 0.76, and 0.78 respectively. The comparable accuracy of KimiaNet I and IV suggests that site-specific patterns could be easily learned even with fine-tuning
