Understanding Differential Search Index for Text Retrieval
Xiaoyang Chen, Yanjiang Liu, Ben He +2
The Differentiable Search Index (DSI) is a novel information retrieval (IR) framework that utilizes a differentiable function to generate a sorted list of document identifiers in r…
MSQ-Index: A Succinct Index for Fast Graph Similarity Search
Xiaoyang Chen, Hongwei Huo, Jun Huan +1
Graph similarity search has received considerable attention in many applications, such as bioinformatics, data mining, pattern recognition, and social networks. Existing methods fo…
Real affine varieties of nonnegative curvature
Xiaoyang Chen
Let be a smooth real affine variety with compact real points . We show that is diffeomorphic to the normal bundle of $X_{\mathbb{R…
Finiteness of prescribed fibers of local biholomorphisms: a geometric approach
Xiaoyang Chen, Frederico Xavier
Let be a Stein manifold of complex dimension at least two, a local biholomorphism, and . In this paper we formulate sufficient cond…
Riemannian submersions from compact four manifolds
Xiaoyang Chen
We show that under certain conditions, a nontrivial Riemannian submersion from positively curved four manifolds does not exist. This gives a partial answer to a conjecture due to F…
Rigidity theorems for submetries in positive curvature
Xiaoyang Chen, Karsten Grove
We derive general structure and rigidity theorems for submetries , where is a Riemannian manifold with sectional curvature . When applied to a non-tri…
