WebMar 25, 2024 · In “ ETC: Encoding Long and Structured Inputs in Transformers ”, presented at EMNLP 2024, we present the Extended Transformer Construction (ETC), which is a novel method for sparse attention, in which one uses structural information to limit the number of computed pairs of similarity scores. This reduces the quadratic dependency on input ... WebOct 13, 2024 · Structured sparse representation is also adopted for anomaly target detection by using the background endmember features from AA unmixing. Moreover, both the AA unmixing reconstruction error and the structured sparse representation reconstruction error are integrated together to enhance the anomaly target detection …
