Highlights

• Continue VNNI acceleration support, we add optimization for more CNN models including object detection models, enhance model scales generation support for VNNI.

• Add attention based model support, we add Transformer implementation for both lanuage model and translation model.

• RNN optimization, We support LSTM integration with MKL-DNN which acheives ~3x performance speedup.
