Can you describe why and how you using cuckoo hash for embedding?

Hi @wuminbin , basically, hashmap is the best choice for dynamic embedding and cucokoo hash is only one kind of hashmap(KV), we can use the any kind of KV implement to do the same things. I don't know if I answer your question. About why we need dynamic embedding, please refer to RFC of TFRA: https://github.com/tensorflow/recommenders-addons/blob/master/rfcs/20200424-sparse-domain-isolation.md, thank you!
