Based on Learning to Generate Reviews and Discovering Sentiment (Alec Radford, Rafal Jozefowicz, Ilya Sutskever).
Uses parameters of the multiplicative LSTM model with 4,096 units we trained on the Amazon product review dataset introduced in McAuley et al. (2015) . The dataset in de-duplicated form contains over 82 million product reviews from May 1996 to July 2014 amounting to over 38 billion training bytes. Training took one month across four NVIDIA Pascal GPUs, with our model processing 12,500 characters per second.

NOTE: It takes a while for this model to load weights so the first run can be extremely slow. Once the model is loaded all subsequent calls are fast. The model runs on a GPU.
