Computational Science — the interdisciplinary frame
What does it take to move between economics, statistics, and computation without losing the standards of any of them?
From fragmented data to meaningful structure
Xinmin Chu
I am a computational science researcher and builder working on entity resolution, deduplication, multiview learning, statistical modeling, and evidence-aware evaluation. My work brings together economics, statistics, and computation to recover defensible structure from fragmented, duplicated, or incomplete data. Beyond formal research, I am interested in a broad range of social phenomena and in observing and thinking carefully about how they take shape in everyday life.
Research, building, teaching, and close observation across data and society.
Research
Making merged data answerable for itself
My research asks when two records describe the same real-world thing, how several views of the same data should be combined, and how the resulting decisions — thresholds, blockings, clusterings — can be audited and reproduced rather than taken on faith.
Entity Resolution and Deduplication
When do two records describe the same real-world thing — and how do we make that decision auditable as sources multiply and volume grows?
Record Linkage and Blocking
How can candidate pairs be generated so that linkage stays tractable without silently discarding true matches?
Multiview Representation and Fusion
How should multiple views of the same records — lexical, numeric, embedding, tensor — be combined without letting one view dominate or contradict the rest?
Accepted paper
Missing-data substitution in least squares regression
A data-driven approach to reducing the bias that conventional single substitution can introduce when covariates contain values below a limit of detection. Accepted by the Journal of Applied Statistics on July 19, 2026.
Projects
Research-informed software
Active Research Program ERBOT
An R-based entity-resolution research program spanning multiview representation, scalable blocking, threshold selection, clustering, and evaluation integrity.
Active Public Field Guide ChuKits
A bilingual field guide for identifying and understanding data-center, HPC/AI, mining-facility, and related technical tools and equipment, with privacy-conscious image handling, evidence-based abstention, and structured user correction.
Experimental Prototype DreamReality
An experimental prototype for capturing dream narratives and transforming them into structured storyboards and visual media while preserving the relationship between the original account and generated artifacts.
Beyond the lab
Close observation
Outside formal research, I pay attention to a wide range of social phenomena and write from observation, experience, and sustained reflection. Notes will collect essays, fiction, poems, travel writing, and shorter pieces as they are prepared.
