Keras 83 In this chapter, let us write a simple Long Short Term Memory (LSTM) based RNN to do sequence analysis. A sequence is a set of values where each value corresponds to

It is short and simple. It has two bidirectional LSTM (Long Short-Term Memory Layer) layers and two dense layers interleaved with dropouts. The LSTM layers help to learn the probabilities of words occurring Sequential([ layers.Bidirectional( layers.LSTM(64, return_sequences=True), input_shape=(MAX_SEQ_LEN, WORD2VEC_LEN) ), layers.Dropout(0.5), layers.Bidirectional(layers.LSTM(32, return_sequences=False)), layers synthetic data was added to the training mix.

of size N, and an embedding table of shape (N, d). pQRNN demonstrated a model 140x smaller than an LSTM with pre-trained embeddings. An on-device friendly implementation of pQRNN is available in the Tensorflow vanishing gradients. This led to the rise of novel cell designs like Long and Short Term Memory19 (LSTM) and Gated Recurrent Unit20 (GRU) cells. However, RNNs are slow to train because of their sequential
