This Twitter feed will feature news from the Scalable Similarity Search project, sss.projects.itu.dk which started May 1, 2014.
kNN is now available for Elasticsearch on AWS (opendistro.github.io/for-ela…). Nice to see that the choice of algorithm was informed by ANN-Benchmarks (ann-benchmarks.com/), co-developed by the @ERC_SSS project!

Enjoyed speaking at WADS 2019 on Set Similarity! Slides available at itu.dk/people/pagh/papers/WA…

Serious attempts at improving nearest neighbor algorithms in practice should demonstrate their worth on ann-benchmarks (co-developed by @ERC_SSS team members Martin Aumüller and Alec Faithful)!

Huge thanks to Martin Aumüller, Tobias Christiani, and Michael Vesterli for making this possible.

PUFFINN was developed to eliminate the parameter tuning that is required for most nearest neighbor search algorithms with theoretical guarantees. Let us know what you think of it!

New paper! “Fair Near Neighbor Search: Independent Range Sampling in High Dimensions“ by M. Aumüller @RasmusPagh1 and myself: arxiv.org/abs/1906.01859. Given a query q, we show how to evenly sample near neighbors of q in a high dimensional space. (1/2)

Microsoft’s Space Partition Tree And Graph (SPTAG), now available on @GitHub, takes advantage of vectors to search through billions of pieces of info in milliseconds: aka.ms/AA52hxp

Today marks the end of the generous funding of @ERC_SSS by @ERC_Research. Special thanks to the talented people who contributed, directly or as collaborators. But we are not done! New results are in the pipeline, and I am excited about the progress that has been made. Stay tuned!

I thought about whether monochromatic = bichromatic closest pair for an annoyingly long time (probably a few days a year, since 2011) so I am glad to see progress on it! eccc.weizmann.ac.il/report/2…

The talk on "How to Prepare Your Vectors" will be given again at Nvidia on November 15, 11 AM.
Favorite recipes for preparing high-dimensional vectors from @RasmusPagh1 presented at @Google, Mountain View, October 11 at 1 PM.

We thank Samuel McCauley for two great years at a post-doc in @ERC_SSS, and wish him good luck with his next post-doc in Boston!
