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. 1

    Generate Forecasts

    Run XTFT or PINN-based model to produce probabilistic subsidence predictions with confidence intervals.

  2. 2

    Apply k-Diagram

    Feed predictions into the k-diagram toolkit to produce polar diagnostic plots across all coverage levels.

  3. 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.
