Testing performance of Tensorflow’s fixed-point-quantization on x86_64 cpu

Google has published their quantization method on this paper. It use int8 to run feed-forward but float32 for back-propagation, since back-propagation need more accurate to accumulate gradients. I got a question right after reading the paper: why all the performance test works are on platform of mobile-phone (ARM architecture)? The… Read more »
