Incremental learning from chunk data for IDR/QR

作者:

Highlights:

• We propose a new implementation of the batch IDR/QR method.

• Our new implementation is theoretically equivalent to the original one but is more efficient.

• Based on our new implementation of batch IDR/QR, we propose the chunk IDR method.

• Chunk IDR is capable of processing multiple data instances at a time.

• Chunk IDR can accurately update the discriminant vectors when new data items are added dynamically.
