temporal-validation

A reproducible ML study of Codeforces difficulty prediction, cold-start limits, temporal validation, and statement-structure features.

Temporal partitioning and backtesting for time-correlated datasets

Production-aware credit-card fraud detection. Temporal splits, cost-sensitive thresholds, calibrated probabilities, Optuna tuning, and a Streamlit dashboard.

Reproducible temporal-validation pipeline for suicidal-ideation prediction in employed U.S. adults across 2015-2023 NSDUH data.

Binary classifier with Venn-ABERS calibration, temporal validation, hyper-parameter optimisation, and fraud detection out of the box

Code, configurations and outputs for the paper Identifiability of Policy-Change Attribution from Endpoint Logs of First-Match Firewalls, with its motivating enterprise firewall audit

Public-safe, runnable reconstruction of breast cancer risk-model external validation, calibration, local adaptation, and temporal validation.

A published Llama fine-tune scores 100% on its historical split. The audit shows why: a depth-2 tree ties it, a two-field rule reproduces all 1,000 labels, and one unrelated note flips 84 of 84 negative predictions.

CogniGuard-ML: A Leakage-Resistant Explainable Automated Machine Learning Framework for Early Cognitive Function Decline Risk Prediction Using Population Health Data

A reproducible electoral data science model for the 2026 U.S. midterms, combining temporal validation, House and Senate forecasts, Monte Carlo simulation, and an interactive dashboard.

PostgreSQL-native, simplified fork of DSSG triage for temporal ML

Evidence-first out-of-year consumer payment-choice benchmark using public Atlanta Fed SDCPC data

R Shiny dashboard demonstrating validation-first analytics for clinical trial duration forecasting. Random split R² = 0.84 vs time-based R² = 0.04—why validation strategy matters more than model selection.

Applied NLP decision-support project for CFPB complaint routing, comparing TF-IDF + Linear SVM with DistilBERT through leakage-safe evaluation, selective routing, Human Review, and 2025 retrospective analysis.

CLOSED research program: preregistered test of BTC/ETH derivatives features for 24h BTC direction prediction. Honest negative result under exact-Decimal, tamper-evident, point-in-time protocol. 2025 window never opened.

HCMC real-estate price intelligence with property identity resolution, leakage-safe temporal validation, ExtraTrees/Ridge modeling, conformal intervals, comparables, FastAPI, and Streamlit.

Temporal evaluation of feature-side inflation in database-driven predictors: evidence dating, vintage-matched snapshot rebuilders and rank-stability diagnostics

Evaluation-aware insurance fraud and claim-risk ML pipeline with temporal validation, leakage auditing, imbalance handling, threshold tuning, business-loss analysis, and Streamlit scoring.

Python CLI that detects entity leakage, reversed-role leakage, and temporal overclaiming in influenza antigenicity evaluations.

Synthetic temporal-risk benchmark with delayed labels, chronological validation, an isolated reference solver, submission grading and 18 tests.
