# Progress Curve Fitting


## Purpose

Fit parametric curves to historical SOTA performance data, identify inflection points representing paradigm shifts, and extrapolate future progress trajectories. Produces structured data suitable for visualization and trend analysis.

## Input Schema

| Field | Type | Description |
|-------|------|-------------|
| historical_scores | object[] | Array of {method, score, date, dataset, metric} sorted chronologically |
