Faster Maximum Inner Product Search in High Dimensions

no code implementations14 Dec 2022 Mo Tiwari, Ryan Kang, Je-Yong Lee, DongHyun Lee, Chris Piech, Sebastian Thrun, Ilan Shomorony, Martin Jinye Zhang

We provide theoretical guarantees that BanditMIPS returns the correct answer with high probability, while improving the complexity in $d$ from $O(\sqrt{d})$ to $O(1)$.

BanditPAM: Almost Linear Time $k$-Medoids Clustering via Multi-Armed Bandits

2 code implementations11 Jun 2020 Mo Tiwari, Martin Jinye Zhang, James Mayclin, Sebastian Thrun, Chris Piech, Ilan Shomorony

Current state-of-the-art $k$-medoids clustering algorithms, such as Partitioning Around Medoids (PAM), are iterative and are quadratic in the dataset size $n$ for each iteration, being prohibitively expensive for large datasets.
