the vocabulary lookup tensor is updated at the time interval set in the
      `UpdateEmbeddingCallback` based on the most up-to-date vocabulary hash
      table maintained by the layer. If this layer is not used in conjunction
      with `UpdateEmbeddingCallback` the behavior of the layer would be same as
      `keras.layers.Embedding`.
*  `keras.optimizers.Adam`
    * Added the option to set adaptive epsilon to match implementations with Jax
