Nevertheless, Query-Key Norm remains promisingly convergent with SDM's requirement of "Sparse Distributed Memory (SDM), is a biologically plausible form of associative memory". For each layer we take the maximum softmax input for a given text prompt for each head. We then take the mean of this maximum for each head and plot this for each text input. Hamming distances that read to and write from fewer patterns. Small and Large models aggregated across all text data for all heads and layers.
