Structural-Aware Matrix Profile Objective

Auto-generated stub. Edit this file to add more details.

A loss function for sequence modeling that utilizes the Matrix Profile to measure and optimize for similarity in temporal subsequences rather than just point-wise accuracy.

Why It Matters

This novel loss function shifts evaluation from point-wise errors to subsequence-level similarity, specifically addressing phase shifts common in precipitation forecasting.
