Embedding layer example
WebNov 18, 2024 · The embedding layer has a simple capability: It turns positive integers (indexes) into dense vectors of fixed size. Let’s see it with a basic example: I passed the output from the TextVectorization example as input and set the output dimension to two. Therefore, each of our input integers is now represented with a 2-dims vector.
