Researchers have developed a novel method for learning multi-head softmax attention, a key component in Transformer models. This new algorithm can recover the parameters of these attention heads without requiring prior knowledge of orthogonal subspaces, a limitation of previous approaches. The method involves merging heads with identical weights and summing their corresponding values, effectively creating a canonical representation. The algorithm achieves this by querying arbitrary token sequences and analyzing the resulting scalar outputs, using a specific number of queries to reconstruct the attention head parameters with high probability.
