iFVS: Towards Instance-Optimized Filtered Vector Search
Abdullah Al-Mamun, Yeasir Rayhan, Walid G. Aref
Filtered vector search (FVS) is increasingly important in modern AI + DB systems, where vector similarity search is combined with relational predicates. Quantization plays a vital…
Virtual-Memory Assisted Buffer Management In Tiered Memory
Yeasir Rayhan, Walid G. Aref
Tiered memory architectures have gained significant traction in the database community in recent years. In these architectures, the on-chip DRAM of the host processor is typically…
Gen-DBA: Generative Database Agents
Yeasir Rayhan, Walid G. Aref
Leveraging Machine Learning to optimize database systems, referred to as Machine Learning for Databases (ML4DB, for short), dates back to the early 1990s, spanning indexing techniq…
Lightning Prediction under Uncertainty: DeepLight with Hazy Loss
Md Sultanul Arifin, Abu Nowshed Sakib, Yeasir Rayhan +1
Lightning, a common feature of severe meteorological conditions, poses significant risks, from direct human injuries to substantial economic losses. These risks are further exacerb…
An Empirical Survey and Benchmark of Learned Distance Indexes for Road Networks
Gautam Choudhary, Libin Zhou, Yeasir Rayhan +1
The calculation of shortest-path distances in road networks is a core operation in navigation systems, location-based services, and spatial analytics. Although classical algorithms…
P-MOSS: Scheduling Main-Memory Indexes Over NUMA Servers Using Next Token Prediction
Yeasir Rayhan, Walid G. Aref
Ever since the Dennard scaling broke down in the early 2000s and the frequency of the CPUs stalled, vendors have started to increase the core count in each CPU chip at the expense…
