WebThis column produces the sparse IDs that are inputs to the embedding lookup. dimension : An integer specifying dimension of the embedding, must be > 0. combiner : A string specifying how to reduce if there are multiple entries in a single row. WebJan 19, 2024 · With embeddings representation, every word will be transformed into a vector of real numbers with a chosen length (embedding_size). This example is created with embedding_size = 3 in order to easily output the embeddings vectors. It means that every word is represented by a vector of 3 real numbers.
