HNSW with Accuracy Guarantees Using Graph Spanners
Minghao Li, Raghav Mittal, Sanjivni Rana +3
Hierarchical Navigable Small World (HNSW) graphs serve as the industry standard due to their logarithmic complexity and strong empirical performance. However, HNSW relies on greedy…
A Distributed Solution for Efficient K Shortest Paths Computation over Dynamic Road Networks
Ziqiang Yu, Xiaohui Yu, Nick Koudas +2
The problem of identifying the k-shortest paths KSPs for short in a dynamic road network is essential to many location-based services. Road networks are dynamic in the sense that t…
Effective Explanations for Entity Resolution Models
Tommaso Teofili, Donatella Firmani, Nick Koudas +3
Entity resolution (ER) aims at matching records that refer to the same real-world entity. Although widely studied for the last 50 years, ER still represents a challenging data mana…
LES3: Learning-based Exact Set Similarity Search
Yifan Li, Xiaohui Yu, Nick Koudas
Set similarity search is a problem of central interest to a wide variety of applications such as data cleaning and web search. Past approaches on set similarity search utilize eith…
Data Acquisition for Improving Machine Learning Models
Yifan Li, Xiaohui Yu, Nick Koudas
The vast advances in Machine Learning over the last ten years have been powered by the availability of suitably prepared data for training purposes. The future of ML-enabled enterp…
Efficient Construction of Nonlinear Models over Normalized Data
Zhaoyue Chen, Nick Koudas, Zhe Zhang +1
Machine Learning (ML) applications are proliferating in the enterprise. Relational data which are prevalent in enterprise applications are typically normalized; as a result, data h…
