PlantDoc — tiny variant

Warning: this is a debug-grade subset, not a faithful subsample for analysis. Use it for test suites, smoke tests, and notebook iteration. For substantive work, use geraldmc/plantdoc-full.

A 164-image stratified subsample of geraldmc/plantdoc-full, built to support fast iteration. Loading is roughly a 50 MB download instead of ~950 MB, and a pass over the dataset takes seconds rather than minutes.

Quick start

from datasets import load_dataset

ds = load_dataset("geraldmc/plantdoc-tiny", revision="v0.1.0", split="train")
print(len(ds))    # 164

Inside the iResearch Institute 2026 Virtual Lab:

import irilab2026 as iri

metadata_df, hf_dataset = iri.load_plantdoc(variant="tiny")

What's in this dataset

• 164 images stratified across 28 classes, 83 train + 81 test
• Schema identical to plantdoc-full — same 8 columns (image + 7 metadata), same values for any image that appears in both
• Subsample rule: min(3, available) per class per split, with a fixed seed

For every non-orphan class, this means 3 train + 3 test = 6 images. The orphan class (Tomato two spotted spider mites leaf) appears with its 2 train images and 0 test images, exactly as in the full variant.

Schema, normalization, caveats

See the full variant's dataset card for:

• Column descriptions and types
• Normalization rules for host and disease
• The orphan-class caveat
• Filename quirks
• Citation and license details

The schema is identical between the two variants; duplicating it here invites drift.

Subsample parameters

• Per-class budget: min(3, available) per (class, split)
• Seed: 42 (passed as random_state to pandas .sample())
• Source: geraldmc/plantdoc-full at revision v0.1.0

The subsample is fully deterministic given these three parameters. Re-running the build script with the same source and seed produces byte-identical metadata. Image bytes also match exactly because the same upstream files are referenced.

What this dataset is NOT for

• Training a classifier. 3 training images per class is far too few to learn anything; this isn't a "small training set" — it's a fixture for code paths.
• Measuring per-class accuracy. Per-class test set sizes here are 1–3 images; any "accuracy" you compute is dominated by sampling noise.
• Comparing model architectures. Any signal would be noise at this scale.
• Reporting results in a paper. Whatever you find on the tiny variant is not a finding about PlantDoc — it's a finding about 164 images that happen to live under this repo ID.

What this dataset IS for

• Test suite use. Fast assertion that loader code, Dataset wrappers, and training pipelines run end-to-end without surprise.
• Notebook iteration. Debugging a preprocessing pipeline or augmentation strategy without paying for the full dataset's load time.
• CI runs. Tests that exercise loader behavior can use this variant on every push without burning minutes on downloads.
