Pens & Pencils (Tabular)

This dataset contains real-world measurements of pens and pencils collected manually, with augmentation for experimentation in ML education.

Features (6)

length_cm (float)
weight_g (float)
is_metallic (0/1)
body_shape (categorical; e.g., round, hexagonal, triangular)
has_clip (0/1)
is_pen (binary target; 1 = pen, 0 = pencil)

Splits

original: 30 manually measured rows (≥30)
augmented: 300 synthetic rows (≥300), label-preserving jitter on numeric fields

EDA

See assets/feature_dists.png and assets/target_dist.png for summary distributions.

Intended Use

Educational use for practice with tabular data, augmentation, and Hugging Face Datasets.

Ethical Notes

All data collected is from personal, non-sensitive objects (pens/pencils). No PII.

AI Usage

Some augmentation/plot code was assisted with GenAI, transparently documented in this notebook. The majority of code was referenced from the inclass tabular dataset example refactored for my use case
