Abstract: A summation-by-parts precise integration time domain (SBP-PITD) method with provable energy stability is proposed and implemented in 1-D, 2-D, and 3-D cases. Various typical boundary ...

Abstract: Cross-domain few-shot scene classification (CDFSSC) aims to tackle the challenge of classifying target domain data with limited labeled samples under distribution shift and category mismatch ...
