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. I recover defensible structure from fragmented, duplicated, or incomplete data — and turn ideas into usable software.
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?
Projects
Research-informed software
Active Research ProgramERBOT
An R-based entity-resolution research program spanning multiview representation, scalable blocking, threshold selection, clustering, and evaluation integrity.
Active Public Field GuideChuKits
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.
Live Web AppGushenle
A personal and family investment companion web app: momentum diagnosis from daily price action, behavior nudges against chasing highs and panic selling, and educational stock-themed games.
Live Writing CommunityWrightbar
A Chinese-language creative writing community: co-written works, a character archive of everyday people, and contribution points that recognize each participant.
Experimental PrototypeSandX
The R package behind ERBOT: scalable entity-resolution blocking with honest evaluation — every claim paired with a falsifiable experiment.
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.
