Locality sensitive Negative Sampling (LNS)

This repository includes the source code for two efficient negative sampling schemes proposed in the ICML 2021 paper A Tale of Two Efficient and Informative Negative Sampling Distributions

Dataset

The dataset can be downloaded in Amazon-670K. Note that the data is sorted by labels, so please shuffle at least the validation/testing data.
