The Problem
Most forecasting models produce uncertainty estimates, but few practitioners know how to interpret them. Coverage gaps, overconfidence, and poor calibration go undetected — leading to decisions based on false confidence.
The Innovation
The k-diagram framework introduces a polar coordinate system for visualizing multiple dimensions of forecast quality simultaneously — coverage, calibration, severity, and reliability — in a single, interpretable chart.
A Concrete Application: Subsidence Forecasting
How k-diagram diagnostics improved real-world model evaluation
- 1
Generate Forecasts
Run XTFT or PINN-based model to produce probabilistic subsidence predictions with confidence intervals.
- 2
Apply k-Diagram
Feed predictions into the k-diagram toolkit to produce polar diagnostic plots across all coverage levels.
- 3
Interpret & Improve
Identify coverage gaps, overconfident intervals, or systematic biases and retrain accordingly.
What Can k-Diagram Answer?
The k-diagram toolkit turns abstract uncertainty metrics into visual diagnostics.
“Is my model well-calibrated?”
Visualize whether prediction intervals actually contain the true value at the stated confidence level.
“Where does coverage fail?”
Identify specific coverage levels or time horizons where the model systematically under- or over-predicts.
“How severe are the errors?”
Quantify the magnitude of coverage gaps and their potential impact on downstream decisions.
