GRAIL: Efficient Time-Series Representation Learning

Summary: GRAIL introduces a unified time-series representation preserving a user-specified similarity. It expresses each series as a linear combination of landmark series, via clustering and kernel-approximation, enabling linear-time analytics for querying, classification, and clustering.
