WebMay 1, 2024 · 4. In your implementation, in scaled_dot_product you scaled with query but according to the original paper, they used key to normalize. Apart from that, this implementation seems Ok but not general. class MultiAttention (tf.keras.layers.Layer): def __init__ (self, num_of_heads, out_dim): super (MultiAttention,self).__init__ () self.out_dim ... For this purpose, you will create a class called DotProductAttention that inherits from the Layerbase class in Keras. In it, you will create the class method, call(), that takes as input arguments the queries, keys, and values, as well as the dimensionality, $d_k$, and a mask (that defaults to None): The first step is to perform a … See more This tutorial is divided into three parts; they are: 1.
