The Million Experts Mixture model proposed by Google DeepMind, a revolutionary study that has taken a significant step forward in the Transformer architecture. Imagine a model capable of sparse retrieval from a million mini-experts - doesn't that sound a bit like a science fiction novel plot? Yet, this is the latest research achievement from DeepMind. The core of this research is a highly parameter-efficient expert retrieval mechanism, which separates the computation cost from the parameter coun
