Abstract:
We present a new algorithm RXTX that computes product of matrix by its transpose XX^T for any size of X. RXTX uses 5% fewer additions and multiplications than other algorithms. Algorithm was discovered through combination of Machine Learning-based Search and Combinatorial Optimization. We discuss theoretical and practical implications, connections to AlphaEvolve and AlphaTensor.
