Dataset Summary
The Iris dataset is a classic multivariate dataset introduced by Ronald Fisher in 1936. It contains 150 samples of iris flowers from three different species: Iris setosa, Iris versicolor, and Iris virginica. Each sample has four features: sepal length, sepal width, petal length, and petal width.
This dataset is widely used for classification tasks, especially in machine learning tutorials and benchmarks.
Dataset Structure
- Instances: 150
- Features:
sepal_length(float)sepal_width(float)petal_length(float)petal_width(float)species(label: 0 = setosa, 1 = versicolor, 2 = virginica)
Labels
There are 3 classes:
- 0: Iris setosa
- 1: Iris versicolor
- 2: Iris virginica

Intended Use
This dataset is intended for:
- Educational purposes
- Model prototyping
- Benchmarking classification algorithms
Limitations
- Small dataset: only 150 samples
- Balanced classes, not suitable for testing imbalanced techniques
Example
| sepal_length | sepal_width | petal_length | petal_width | species |
|---|---|---|---|---|
| 5.1 | 3.5 | 1.4 | 0.2 | Iris-setosa |
