WebMar 16, 2024 · The very first layer in the encoder is the self-attention layer, which is the most important part of the encoder. This layer can detect related tokens in the same sequence, no matter how far they are. For example, in the sentence: “The cat is on the mat. Let’s start by importing the required libraries. We can create a simple Keras model by just adding an embedding layer. There are three parameters to the embedding layer 1. input_dim: Size of the vocabulary 2. output_dim: Length of the vector for each word 3. input_length: Maximum length of a sequence In the … See more Embedding layer is one of the available layers in Keras. This is mainly used in Natural Language Processing related applications such as language modeling, but it can also be used with other tasks that involve neural … See more As we know while dealing with textual data, we need to convert it into numbers before feeding into any machine learning model, including neural networks.
