GraphMind: From Operational Traces to Self-Evolving Workflow Automation
Yiwen Zhu, Joyce Cahoon, Anna Pavlenko +13
Complex operational workflows coordinating personnel, tools, and information are central to system operations, yet end-to-end automation remains challenging due to extensive human…
Blue Data Intelligence Layer: Streaming Data and Agents for Multi-source Multi-modal Data-Centric Applications
Moin Aminnaseri, Farima Fatahi Bayat, Nikita Bhutani +17
NL2SQL systems aim to address the growing need for natural language interaction with data. However, real-world information rarely maps to a single SQL query because (1) users expre…
From Textual Columns to Query Plans: A Unified Relational-Semantic Execution Framework for Hybrid Query Processing
Nima Shahbazi, Seiji Maekawa, Nikita Bhutani +1
Real-world table question answering often involves hybrid schemas in which some query-relevant information is explicit in relational columns, while other attributes, predicates, or…
Weighted Set Multi-Cover on Bounded Universe and Applications in Package Recommendation
Nima Shahbazi, Aryan Esmailpour, Stavros Sintos
The weighted set multi-cover problem is a fundamental generalization of set cover that arises in data-driven applications where one must select a small, low-cost subset from a larg…
Fair-Count-Min: Frequency Estimation under Equal Group-wise Approximation Factor
Nima Shahbazi, Stavros Sintos, Abolfazl Asudeh
Frequency estimation in streaming data often relies on sketches like Count-Min (CM) to provide approximate answers with sublinear space. However, CM sketches introduce additive err…
REQUAL-LM: Reliability and Equity through Aggregation in Large Language Models
Sana Ebrahimi, Nima Shahbazi, Abolfazl Asudeh
The extensive scope of large language models (LLMs) across various domains underscores the critical importance of responsibility in their application, beyond natural language proce…
FairEM360: A Suite for Responsible Entity Matching
Nima Shahbazi, Mahdi Erfanian, Abolfazl Asudeh +2
Entity matching is one the earliest tasks that occur in the big data pipeline and is alarmingly exposed to unintentional biases that affect the quality of data. Identifying and mit…
Through the Fairness Lens: Experimental Analysis and Evaluation of Entity Matching
Nima Shahbazi, Nikola Danevski, Fatemeh Nargesian +2
Entity matching (EM) is a challenging problem studied by different communities for over half a century. Algorithmic fairness has also become a timely topic to address machine bias…
A Fair and Memory/Time-efficient Hashmap
Abolfazl Asudeh, Nima Shahbazi, Stavros Sintos
Hashmap is a fundamental data structure in computer science. There has been extensive research on constructing hashmaps that minimize the number of collisions leading to efficient…
Data Coverage for Detecting Representation Bias in Image Datasets: A Crowdsourcing Approach
Melika Mousavi, Nima Shahbazi, Abolfazl Asudeh
Existing machine learning models have proven to fail when it comes to their performance for minority groups, mainly due to biases in data. In particular, datasets, especially socia…
PopSim: An Individual-level Population Simulator for Equitable Allocation of City Resources
Khanh Duy Nguyen, Nima Shahbazi, Abolfazl Asudeh
Historical systematic exclusionary tactics based on race have forced people of certain demographic groups to congregate in specific urban areas. Aside from the ethical aspects of s…
Reliability Evaluation of Individual Predictions: A Data-centric Approach
Nima Shahbazi, Abolfazl Asudeh
Machine learning models only provide probabilistic guarantees on the expected loss of random samples from the distribution represented by their training data. As a result, a model…
Representation Bias in Data: A Survey on Identification and Resolution Techniques
Nima Shahbazi, Yin Lin, Abolfazl Asudeh +1
Data-driven algorithms are only as good as the data they work with, while data sets, especially social data, often fail to represent minorities adequately. Representation Bias in d…
