https://keras.io/api/layers/attention_layers/attention
Dot-product attention layer, a.k.a. Luong-style attention. Inputs are query tensor of shape [batch_size, Tq, dim], value tensor of shape [batch_size, Tv, dim] and key tensor of shape [batch_size, Tv, dim].The calculation follows the steps: Calculate scores with shape [batch_size, Tq, Tv] as a query-key dot product: scores = tf.matmul(query, key, transpose_b=True).
How to add an attention mechanism in keras? - Stack Overflow
https://stackoverflow.com/questions/42918446
Show activity on this post. Attention mechanism pays attention to different part of the sentence: activations = LSTM (units, return_sequences=True) (embedded) And it determines the contribution of each hidden state of that sentence by. Computing the aggregation of each hidden state attention = Dense (1, activation='tanh') (activations)
