Role of Feature Projection in Attention Normalization
An engineer is optimizing a language model to handle very long text sequences, such as entire books. They decide to replace the standard attention mechanism with one that projects query and key vectors into a different feature space. This change allows them to substitute the original, complex normalization function with a much simpler scaling operation. What is the fundamental trade-off associated with this specific modification?
