Here the authors propose an adversarial contextual model for detecting moving objects in images.

A deep neural network is trained to predict the optical flow in a region using information from everywhere else but that region (context), while another network attempts to make such context as uninformative as possible.

The result is a model where hypotheses naturally compete with no need for explicit regularization or hyper-parameter tuning.

This method requires no supervision whatsoever, it outperforms several methods that are pre-trained on large annotated datasets.

Amazing project success for #DeepLearning for #Radiologists

This CNN model for breast cancer did screening exam classification, trained and evaluated on over 200,000 exams (over 1,000,000 images).

Accuracy? ~ 90% in predicting whether there is a cancer in the breast, when tested on the screening population.

It was a two-stage training procedure, which allows us to use a very high-capacity patch-level network to learn from pixel-level labels alongside a network learning from macroscopic breast-level labels.
