Incremental Tensor-Train Compression from Streaming TT-Formatted Data: Applications to Reduced-Order Modeling

A deterministic incremental TT compression algorithm that operates directly on streaming TT-formatted data and corresponds to a compressed analogue of standard proper orthogonal decomposition for full-order snapshot data, enabling reduced-order models to be constructed directly from streaming low-rank solution data through operations on TT cores, without first reconstructing full snapshots.
