TSEXPLAIN: Explaining Aggregated Time Series by Surfacing Evolving Contributors
Yiru Chen, Silu Huang
Aggregated time series are generated effortlessly everywhere, e.g., "total confirmed covid-19 cases since 2019" and "total liquor sales over time." Understanding "how" and "why" th…
Frugal Optimization for Cost-related Hyperparameters
Qingyun Wu, Chi Wang, Silu Huang
The increasing demand for democratizing machine learning algorithms calls for hyperparameter optimization (HPO) solutions at low cost. Many machine learning algorithms have hyperpa…
ABC: Efficient Selection of Machine Learning Configuration on Large Dataset
Silu Huang, Chi Wang, Bolin Ding +1
A machine learning configuration refers to a combination of preprocessor, learner, and hyperparameters. Given a set of configurations and a large dataset randomly split into traini…
Navigating the Data Lake with Datamaran: Automatically Extracting Structure from Log Datasets
Yihan Gao, Silu Huang, Aditya Parameswaran
Organizations routinely accumulate semi-structured log datasets generated as the output of code; these datasets remain unused and uninterpreted, and occupy wasted space - this phen…
Adaptive Sampling for Rapidly Matching Histograms
Stephen Macke, Yiming Zhang, Silu Huang +1
In exploratory data analysis, analysts often have a need to identify histograms that possess a specific distribution, among a large class of candidate histograms, e.g., find countr…
OrpheusDB: Bolt-on Versioning for Relational Databases
Silu Huang, Liqi Xu, Jialin Liu +2
Data science teams often collaboratively analyze datasets, generating dataset versions at each stage of iterative exploration and analysis. There is a pressing need for a system th…
Optimally Leveraging Density and Locality to Support LIMIT Queries
Albert Kim, Liqi Xu, Tarique Siddiqui +3
Existing database systems are not optimized for queries with a LIMIT clause---operating instead in an all-or-nothing manner. In this paper, we propose a fast LIMIT query evaluation…
Finding Multiple New Optimal Locations in a Road Network
Ruifeng Liu, Ada WaiChee Fu, Zitong Chen +2
We study the problem of optimal location querying for location based services in road networks, which aims to find locations for new servers or facilities. The existing optimal sol…
Towards a unified query language for provenance and versioning
Amit Chavan, Silu Huang, Amol Deshpande +3
Organizations and teams collect and acquire data from various sources, such as social interactions, financial transactions, sensor data, and genome sequencers. Different teams in a…
Principles of Dataset Versioning: Exploring the Recreation/Storage Tradeoff
Souvik Bhattacherjee, Amit Chavan, Silu Huang +2
The relative ease of collaborative data science and analysis has led to a proliferation of many thousands or millions of of the same datasets in many scientific and comm…
(α, k)-Minimal Sorting and Skew Join in MPI and MapReduce
Silu Huang, Ada Wai-Chee Fu
As computer clusters are found to be highly effective for handling massive datasets, the design of efficient parallel algorithms for such a computing model is of great interest. We…
Temporal Graph Traversals: Definitions, Algorithms, and Applications
Silu Huang, James Cheng, Huanhuan Wu
A temporal graph is a graph in which connections between vertices are active at specific times, and such temporal information leads to completely new patterns and knowledge that ar…
