Binary Quantizer

One-bit quantization is a general tool to execute a complex model,such as deep neural networks, on a device with limited resources,such as cell phones. Naively compressing weights into one bityields an extensive accuracy loss. One-bit models, therefore, re-quire careful re-training. Here we introduce a class functions de-vised to be used as a regularizer for re-training one-bit models. Us-ing a regularization function, specifically devised for binary quanti-zation, avoids heuristic touch of the optimization scheme and savesconsiderable coding effort
