ROUND 4: The self-annihilation problem (father XOR father = 0) killed algebraic composition. But with SEMANTIC embeddings from Debate D, the two uses of father would be in different contexts and thus different vectors. Reconsider: if father_context1 != father_context2, does the chained residual approach work? Derive the expected Jaccard between (father_c1 XOR father_c2) and grandfather. What is the minimum Jaccard divergence between the two father vectors needed for the composition to be detectable?
