Retrieval with Learned Similarities

1 code implementation22 Jul 2024 Bailu Ding, Jiaqi Zhai

We establish Mixture-of-Logits (MoL) as a universal approximator of similarity functions, demonstrate that MoL's expressiveness can be realized empirically to achieve superior performance on diverse retrieval scenarios, and propose techniques to retrieve the approximate top-k results using MoL with tight error bounds.

DCI: An Accurate Quality Assessment Criteria for Protein Complex Structure Models

no code implementations30 Jun 2024 Wenda Wang, Jiaqi Zhai, He Huang, Xinqi Gong

In this work, we proposed DCI score, a new evaluation strategy for protein complex structure models, which only bases on distance map and CI (contact-interface) map, DCI focuses on the prediction accuracy of the contact interface based on the overall evaluation of complex structure, is not inferior to DockQ in the evaluation accuracy according to CAPRI classification, and is able to handle the non-docking situation better than DockQ.

Revisiting Neural Retrieval on Accelerators

3 code implementations6 Jun 2023 Jiaqi Zhai, Zhaojie Gong, Yueming Wang, Xiao Sun, Zheng Yan, Fu Li, Xing Liu

A key component of retrieval is to model (user, item) similarity, which is commonly represented as the dot product of two learned embeddings.
