RAIRS: Optimizing Redundant Assignment and List Layout for IVF-Based ANN Search
Zehai Yang, Shimin Chen
IVF is one of the most widely used ANNS (Approximate Nearest Neighbors Search) methods in vector databases. The idea of redundant assignment is to assign a data vector to more than…
LITS: An Optimized Learned Index for Strings (An Extended Version)
Yifan Yang, Shimin Chen
Index is an important component in database systems. Learned indexes have been shown to outperform traditional tree-based index structures for fixed-sized integer or floating point…
Density-optimized Intersection-free Mapping and Matrix Multiplication for Join-Project Operations (extended version)
Zichun Huang, Shimin Chen
A Join-Project operation is a join operation followed by a duplicate eliminating projection operation. It is used in a large variety of applications, including entity matching, set…
Updatable Learned Index with Precise Positions
Jiacheng Wu, Yong Zhang, Shimin Chen +3
Index plays an essential role in modern database engines to accelerate the query processing. The new paradigm of "learned index" has significantly changed the way of designing inde…
Storing and Querying Large-Scale Spatio-Temporal Graphs with High-Throughput Edge Insertions
Mengsu Ding, Muqiao Yang, Shimin Chen
Real-world graphs often contain spatio-temporal information and evolve over time. Compared with static graphs, spatio-temporal graphs have very different characteristics, presentin…
Efficient Graph Computation for Node2Vec
Dongyan Zhou, Songjie Niu, Shimin Chen
Node2Vec is a state-of-the-art general-purpose feature learning method for network analysis. However, current solutions cannot run Node2Vec on large-scale graphs with billions of v…
i2MapReduce: Incremental MapReduce for Mining Evolving Big Data
Yanfeng Zhang, Shimin Chen, Qiang Wang +1
As new data and updates are constantly arriving, the results of data mining applications become stale and obsolete over time. Incremental processing is a promising approach to refr…
