A Case for the T-statistic

Introduction undefined, I began eager about the parallels between point-anomaly detection and trend-detection. In relation to points, it’s generally intuitive, and the z-score solves most problems. What took me some time to determine was applying...

Constructing a Self-Healing Data Pipeline That Fixes Its Own Python Errors

AM on a Tuesday (well, technically Wednesday, I suppose), when my phone buzzed with that familiar, dreaded PagerDuty notification. I didn’t even must open my laptop to know that the daily_ingest.py script had failed....

Google Trends is Misleading You: How one can Do Machine Learning with Google Trends Data

. What a present to society that is. If not for google trends, how would we've ever known that more Disney movies released within the 2000s led to fewer divorces within the UK. Or that drinking...

Time Series Isn’t Enough: How Graph Neural Networks Change Demand Forecasting

in supply-chain planning has traditionally been treated as a time-series problem. Each SKU is modeled independently. A rolling time window (say, last 14 days) is used to predict tomorrow’s sales. Seasonality is captured, promotions are added,...

Bridging the Gap Between Research and Readability with Marco Hening Tallarico

What motivates you to take dense academic concepts (like Stochastic Differential Equations) and switch them into accessible tutorials for the broader TDS community? It’s natural to wish to learn all the pieces in its natural...

A Geometric Method to Spot Hallucinations Without an LLM Judge

of birds in flight. There’s no leader. No central command. Each bird aligns with its neighbors—matching direction, adjusting speed, maintaining coherence through purely local coordination. The result's global order emerging from local consistency. Now imagine...

When Shapley Values Break: A Guide to Robust Model Explainability

Explainability in AI is important for gaining trust in model predictions and is extremely essential for improving model robustness. Good explainability often acts as a debugging tool, revealing flaws within the model training process....

Why Your ML Model Works in Training But Fails in Production

, I worked on real-time fraud detection systems and suggestion models for product corporations that looked excellent during development. Offline metrics were strong. AUC curves were stable across validation windows. Feature importance plots told...
