Convolutional neural networks with low-rank regularization. Breast cancer remains the most common type of cancer and the leading cause of cancer-induced mortality among women with 2.4 million new cases diagnosed and 523,000 deaths per year. This will cause several problems: big store space requirement, large run-time memory consumption during inference, higher classification latency due to the millions of computing operations. Each hybrid model is obtained by using a subset of the training data. We propose another different channel pruning method, which can accurately control how many channels are pruned. Then the unimportant channels with lower weights are discarded to make the network compact. Our dataset is not only the largest publicly released dataset for breast cancer histopathological image classification, but it covers as many different subclasses spanning different age groups as possible, thus providing enough data diversity to alleviate the problem of relatively low classification … In: Systems, Man, Q7 and Cybernetics (SMC), 2017 IEEE International Conference On.
