First Deep Learner to win a medical imaging contest
First Deep Learner to win cancer detection contests
In September, 2012, our Deep Learning Neural Network (NN) won the ICPR 2012 Contest on Mitosis Detection in Breast Cancer Histological Images [10,10a] - a paper on this was published at MICCAI 2013 . To our knowledge, this was the first Deep Learner to win a contest on object detection in large images (2048 x 2048 x 3 pixels).
One year later, in Nagoya, Japan, on September 22 at the MICCAI 2013 conference organised by the Society for Medical Image Computing and Computer Assisted Intervention, our deep NN also won the international MICCAI 2013 Grand Challenge on Mitosis Detection . Title defended!
This was made possible through the efforts of my co-workers Dr. Dan Claudiu Ciresan and Dr. Alessandro Giusti. Over 80 research groups (universities and companies) registered; 14 submitted results. The gap between best and second best result is large.
Mitosis detection is important for cancer prognosis, but difficult even for trained experts.
Pure supervised gradient descent (40-year-old efficient reverse mode backpropagation, e.g., [2a,2]) was applied [5,5a] to our special neural architecture [3,4,1] consisting of deep and wide GPU-based Multi-Column Max-Pooling Convolutional Neural Networks (MC GPU-MPCNN or simply deep NN) with alternating weight-sharing convolutional layers [8,5] and max-pooling layers [9,9a,5a,6] topped by fully connected layers  (over two decades, LeCun's lab has produced many improvements of such CNN). This architecture is biologically rather plausible, inspired by early neuroscience-related work [7,8]. (No unsupervised pre-training!)
Since 2011, our GPU-CNNs [3,4] also have been the first systems to achieve human-competitive or even superhuman pattern recognition performance on various other benchmarks [4,13-17]. This has attracted enormous interest from industry since 2011. Many startups as well as leading IT companies and research labs are now using them, too, e.g., . Besides mitosis detection, our deep NN also have many other obvious biomedical applications, such as automatic detection of melanoma, detection of plaque in CT heart scans, segmentation of all kinds of biomedical images - you name it.
The world spends over 10% of GDP on healthcare (over 6 trillion USD per year), much of it on medical diagnosis through expensive experts. Partial automation of this could not only save billions of dollars, but also make expert diagnostics accessible to many who currently cannot afford it.
When we started Deep Learning research over 20 years ago [13,16], 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 human lives.
