In a memory-efficient attention mechanism, the output for a token at position
iis calculated using the formula:Output = (q'_i * μ_i) / (q'_i * ν_i). In this formula,q'_iis the token's processed query, whileμ_iandν_iare aggregations of historical information from all tokens up to and including positioni.
