Ryotaro's paper below won the Best Paper Award at the SIGIR Workshop SynthIR! #SIGIR2026

[松井研 / Matsui Lab @utokyo_bunny]

Atsuki's paper has been accepted to #TMLR! We propose a framework for automatically constructing a sorting algorithm from a given (learned) index. Given index construction O(nC(n)) and rank query O(Q(n)), it yields sorting in O(nC(n)+nQ(n)). https://t.co/Es3tbzB5HI

We will present our work with Atsuki and Martin at #SIGMOD2026 🇮🇳 We provide a theoretical foundation for poisoning attacks against learned indexes, where an adversary inserts malicious data to degrade performance😈 https://t.co/CgK96z2OLT

Atsuki's paper has been accepted to TMLR with a Featured Certification! We present a learned sorting algorithm that sorts data in O(nloglogn) when the data distribution satisfies certain conditions. #TMLR https://t.co/FdiFX9xl6m

We have released the code for LotusFilter presented at CVPR25! It is a super-fast post-processing module that diversifies Faiss search results. You can try it out with `pip install lotf`. Internally, it uses C++17 and Boost Unordered with nanobind. https://t.co/0s5vTyNmV9
