Our Deep Learning neural networks won the ICPR Contest on Mitosis Detection in Breast Cancer Histological Images. Here a preprint of the upcoming MICCAI 2013 paper on this, with Dan Ciresan, Alessandro Giusti, Luca Maria Gambardella: http://www.idsia.ch/~juergen/miccai2013.pdf
This is important for breast cancer prognosis. Humans tend to find it very difficult to distinguish mitosis from other tissue.
When we started Deep Learning research over 20 years ago, limited computing power forced us to focus on toy applications. How things have changed! It is gratifying to observe that today our deep NN may actually help to improve healthcare and save lives.
