# Parametric Shapes Dataset
This is a synthetic dataset of images containing geometric shapes with controllable parameters generated for educational purposes at the University of Toronto.
This dataset contains 7000 synthetic images (32x32) of geometric shapes including circles, rectangles, hexagons, stars, and triangles. Each image is generated with random parameters such as position, size, color, and rotation.
## Dataset Splits
Train: 5,000 images (1,000 per shape)
Validation: 1,000 images (200 per shape)
Test: 1,000 images (200 per shape)
All splits are non-overlapping and generated with different random seeds.
## Parameters
Each image is parameterized by 6 independent factors:
| Factor | Type | Range | Description |
|--------|------|-------|-------------|
| `shape_type` | Categorical | 0-4 | Shape class (0=circle, 1=rectangle, 2=hexagon, 3=star, 4=triangle) |
| `pos_x` | Continuous | 0.2-0.8 | Horizontal position of shape center (normalized) |
| `pos_y` | Continuous | 0.2-0.8 | Vertical position of shape center (normalized) |
| `size` | Continuous | 0.1-0.35 | Size of shape relative to image (radius/width) |
| `color` | Continuous | 0-1 | Hue value (converted to RGB with high saturation) |
| `rotation` | Continuous | 0-2π | Rotation angle in radians (no effect on circles) |
