How Should We Evaluate Data Deletion in Graph-Based ANN Indexes?
Tomohiro Yamashita, Daichi Amagata, Yusuke Matsui
Approximate Nearest Neighbor Search (ANNS) has recently gained significant attention due to its many applications, such as Retrieval-Augmented Generation. Such applications require…
Random Sampling over Spatial Range Joins
Daichi Amagata
Spatial range joins have many applications, including geographic information systems, location-based social networking services, neuroscience, and visualization. However, joins inc…
Approximate Reverse -Ranks Queries in High Dimensions
Daichi Amagata, Kazuyoshi Aoyama, Keito Kido +1
Many objects are represented as high-dimensional vectors nowadays. In this setting, the relevance between two objects (vectors) is usually evaluated by their inner product. Recentl…
How to Mine Potentially Popular Items? A Reverse MIPS-based Approach
Daichi Amagata, Kazuyoshi Aoayama, Keito Kido +1
The -MIPS ( Maximum Inner Product Search) problem has been employed in many fields. Recently, its reverse version, the reverse -MIPS problem, has been proposed. Given an i…
