News editors obtained the following quote from the background information suppli ed by the inventors: “The performance of machine learning and deep learning mode ls for histopathology may be limited by the volume and quality of annotated exam ples used to train these models. Large-scale experiments on supervised image cla ssification problems have shown that model performance continues to improve, up through an order of 50 million training examples. Manually annotating this volum e of data may be prohibitively expensive both in time and cost, and it can be a severe limitation in ensuring systems perform at a clinically relevant level and generalize across institutions.
