LazyAttention: Efficient Retrieval-Augmented Generation with Deferred Positional Encoding
Haocheng Xia, Mihir Pamnani, Hanxi Fang +2
Key-value (KV) caching accelerates inference of large language models (LLMs) by reusing past computations for generated tokens. Its importance becomes even greater in long-context…
Chipmink: Efficient Delta Identification for Massive Object Graph
Supawit Chockchowwat, Sumay Thakurdesai, Zhaoheng Li +2
Ranging from batch scripts to computational notebooks, modern data science tools rely on massive and evolving object graphs that represent structured data, models, plots, and more.…
Large-scale Evaluation of Notebook Checkpointing with AI Agents
Hanxi Fang, Supawit Chockchowwat, Hari Sundaram +1
Saving, or checkpointing, intermediate results during interactive data exploration can potentially boost user productivity. However, existing studies on this topic are limited, as…
Enhancing Computational Notebooks with Code+Data Space Versioning
Hanxi Fang, Supawit Chockchowwat, Hari Sundaram +1
There is a gap between how people explore data and how Jupyter-like computational notebooks are designed. People explore data nonlinearly, using execution undos, branching, and/or…
Kishu: Time-Traveling for Computational Notebooks
Zhaoheng Li, Supawit Chockchowwat, Ribhav Sahu +2
Computational notebooks (e.g., Jupyter, Google Colab) are widely used by data scientists. A key feature of notebooks is the interactive computing model of iteratively executing cel…
AirIndex: Versatile Index Tuning Through Data and Storage
Supawit Chockchowwat, Wenjie Liu, Yongjoo Park
The end-to-end lookup latency of a hierarchical index -- such as a B-tree or a learned index -- is determined by its structure such as the number of layers, the kinds of branching…
Transactional Python for Durable Machine Learning: Vision, Challenges, and Feasibility
Supawit Chockchowwat, Zhaoheng Li, Yongjoo Park
In machine learning (ML), Python serves as a convenient abstraction for working with key libraries such as PyTorch, scikit-learn, and others. Unlike DBMS, however, Python applicati…
A Step Toward Deep Online Aggregation (Extended Version)
Nikhil Sheoran, Supawit Chockchowwat, Arav Chheda +3
For exploratory data analysis, it is often desirable to know what answers you are likely to get before actually obtaining those answers. This can potentially be achieved by designi…
Automatically Finding Optimal Index Structure
Supawit Chockchowwat, Wenjie Liu, Yongjoo Park
Existing learned indexes (e.g., RMI, ALEX, PGM) optimize the internal regressor of each node, not the overall structure such as index height, the size of each layer, etc. In this p…
Probabilistic PolarGMM: Unsupervised Cluster Learning of Very Noisy Projection Images of Unknown Pose
Supawit Chockchowwat, Chandrajit L. Bajaj
A crucial step in single particle analysis (SPA) of cryogenic electron microscopy (Cryo-EM), 2D classification and alignment takes a collection of noisy particle images to infer or…
Airphant: Cloud-oriented Document Indexing
Supawit Chockchowwat, Chaitanya Sood, Yongjoo Park
Modern data warehouses can scale compute nodes independently of storage. These systems persist their data on cloud storage, which is always available and cost-efficient. Ad-hoc com…
Step Out of Your Comfort Zone: More Inclusive Content Recommendation for Networked Systems
Jiaxin Wu, Supawit Chockchowwat
Networked systems are widely applicable in real-world scenarios such as social networks, infrastructure networks, and biological networks. Among those applications, we are interest…
Hypothesis-Driven Skill Discovery for Hierarchical Deep Reinforcement Learning
Caleb Chuck, Supawit Chockchowwat, Scott Niekum
Deep reinforcement learning (DRL) is capable of learning high-performing policies on a variety of complex high-dimensional tasks, ranging from video games to robotic manipulation.…
Functional Generative Design: An Evolutionary Approach to 3D-Printing
Cem C. Tutum, Supawit Chockchowwat, Etienne Vouga +1
Consumer-grade printers are widely available, but their ability to print complex objects is limited. Therefore, new designs need to be discovered that serve the same function, but…
