Nov 21, 2019 · The self-attention library reduces the dimensions from 3 to 2 and when predicting you get a prediction per input vector. The general attention mechanism maintains the 3D data and outputs 3D, and when predicting you only get a prediction per batch. You can solve this by reshaping your prediction data to have batch sizes of 1 if you want ...

Aug 05, 2019 · Attention Layers. Attention is a concept that allows Transformer to focus on a specific parts of the sequence, i.e. sentence. It can be described as mapping function, because in its essence it maps a query and a set of key-value pairs to an output. Query, keys, values, and output are all vectors.
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). Use scores to calculate a distribution with shape [batch_size, Tq, Tv]: distribution = tf.nn.softmax (scores). Use distribution to create a linear combination of value with shape ...
