N·LIN

My work builds predictive models of human behavior — gradient-boosted learners, transformer-based language models, and the psychometric instruments that keep both honest — deployed inside institutional data systems.

01 / Research Programsthree lines of work

01.

Behavioral Prediction

Gradient-boosted tabular models of human outcomes — with calibration checks, honest baselines, and validation discipline treated as the deliverable, not the garnish.

[ prediction · tabular ]

02.

Measurement & Psychometrics

Instruments before models: item response theory, reliability, construct validity — the quantitative-psychology layer under every credible prediction task.

[ irt · reliability · validity ]

03.

Language as Data

Transformer pipelines — DeBERTa-v3 classifiers, sentence encoders, BERTopic — turning free text into structured, analyzable signals for organizational research.

Stage
What happens
Instruments
Frame
Translate a behavioral question into a decision-relevant estimand before any data is touched.
theory → estimand
Measure
Build or audit the instruments; a model on a broken measure is a precise error.
irt · reliability · validity
Model
Tabular and language models, selected against baselines that have earned their numbers.

Deploy
Ship into institutional pipelines; monitor drift the way you would monitor an instrument.

04 / The Ontologyknowledge organization system

This domain is also a knowledge system.

Behind this page sits a personal KOS — private by default: a wiki-shaped ontology database of concepts, methods, artifacts, and the relations between them. Working notes and notebooks sync behind access control; public excerpts are opt-in. The graph also feeds retrieval for my own research agents.
