2nd day at #SIGIR2025 ☀️ After the first keynote, a great talk by @asash on combining joint product quantization and dynamic pruning to accelerate top-k computation. No need to compute all scores anymore! 😎 Work with @craig_macdonald and @ntonellotto .

Happy to share that the OARS@KDD2025 workshop accepts our work. In this work, we turn a sequential recommendation system into a semantic search using generative language models. Apparently, this works really well.
