WebApr 14, 2024 · Increasingly common, training approaches require enormous compute power, as they either conduct negative passage sampling out of a continuously updating refreshing index or require very large batch sizes for in-batch negative sampling. Websampled from batch training data, we uniformly sample negatives from the candidate corpus to serve as additional negatives. This two-stream negative sampling enables us to: (1) …
Webobtain. A popular sampling approach [1, 7] for fitting a softmax out-put distribution is to sample according to the unigram distribution of items. The work in [24] extends unigram sampling to the two-tower setting by using batch negatives, i.e., using the positive items in a mini batch as shared negatives for all queries in the same batch.
