@benwtrent Interesting, Im still not sure if this approach is necessary. I spoke with @searchivarius who is the maintainer of nmslib, and he mentioned that there was some research suggesting this is not required (https://proceedings.neurips.cc/paper_files/paper/2018/hash/229754d7799160502a143a72f6789927-Abstract.html, https://arxiv.org/pdf/1506.03163.pdf). Let me try re-running the Vespa experiments with Lucene without the reduction and see what numbers we get. I dont think in the blog post they posted any comparison to using negative dot product approach (please correct me if I am missing something). -- This is an automated message from the Apache Git Service.
