Research Projects

Six self-contained research notebooks, each written to be readable without prior background in its field, and a formal paper written from each one.

Project Question Headline result
Heart Disease Cross Hospital Research.ipynb Does a clinical risk model survive a move to another hospital? 0.910 internal AUC; directed transfers range 0.571–0.888, so a single "generalization gap" hides the structure
bankruptcy_crisis_stress_test/ Does a bankruptcy model trained in calm years survive a recession? A random forest improves under the 2008–09 crisis (0.755 → 0.798 AUC) while linear and neural models slip
clip_forgetting_forecasting/ Can we forecast how much CLIP will forget, early in fine-tuning? A 5-epoch warm-up forecasts final forgetting at R² = 0.92 — but a zero-parameter persistence rule already reaches 0.85
exoplanet-model-comparison/ What is the exchange rate between accuracy and interpretability? Transparency costs 0.029 AUC on detection and 85% more error on sizing; a label-free physics-informed model lands in between
raddose-phytodosimetry/ Can gene expression identify radiation exposure in an unseen study? 84.2% accuracy and 0.883 AUC under leave-one-study-out, after rejecting exact-dose regression on design grounds
eeg-controls-audit/ Are the perturbation controls used to validate EEG decoders themselves reliable? False-alarm rates span 1.3% to 68.8% across decoders — a control's trustworthiness depends on what you point it at

Papers

papers/ holds one single-column, IEEE-style manuscript per notebook, with LaTeX source, a figure-generation script, the compiled PDF, and a source zip. See papers/README.md for the build instructions and for which papers recompute their numbers versus transcribe them from an executed notebook.

cd papers && ./build.sh

Running a notebook

Each project directory carries its own README.md and requirements.txt. Two projects need data that is licensed and therefore not committed:

  • bankruptcy_crisis_stress_test/ needs mirror/american_bankruptcy.csv.
  • raddose-phytodosimetry/ ships its harmonized matrix and runs as-is.

The rest are self-contained. Every notebook is committed with outputs rendered, so all of them can be read without being run.

Conventions shared across the projects

  • Preprocessing, feature selection, and hyperparameter choice are fitted strictly inside the training boundary, and the notebooks say where that boundary is.
  • The independent unit of evaluation is stated explicitly — a hospital, a dataset, a study, a subject — and uncertainty is quantified at that level, not at the sample level.
  • Every project separates definitions, observations, results, and interpretations, and ends with a claim boundary describing what the evidence does not support.
