Iris Flower Classification - Machine Learning Example

This project demonstrates a basic machine learning workflow using the popular Scikit-Learn library in Python. The script builds a Decision Tree Classifier to classify iris flowers into three species: Setosa, Versicolour, and Virginica based on their features (sepal length, sepal width, petal length, petal width).

Introduction

This project provides a simple example of how to build, train, and evaluate a machine learning model in Python using Scikit-Learn. The Iris dataset is used, which is a standard dataset in the field of machine learning and is ideal for beginners to understand the basic concepts of classification.

Features

Model Training: Train a Decision Tree Classifier on the Iris dataset.
Model Evaluation: Evaluate the model's performance using accuracy score and classification report.
Prediction: Predict the species of new iris samples.
Easy to Understand: A simple, well-commented script to help beginners grasp the fundamentals of machine learning.

Installation

Prerequisites

Ensure you have the following installed:

Python 3.x
Scikit-Learn

Install Scikit-Learn

If you haven't already installed Scikit-Learn, you can do so using pip:

pip install scikit-learn

Usage

Clone the Repository:

Clone the repository to your local machine:

git clone https://github.com/your-username/iris-classification.git

Navigate to the Directory:

Go to the project directory:
```
cd iris-classification
```
Run the Script:

Run the script using Python:
```
python iris_classification.py
```

Running the Program

Once the script is running, it will:

Load the Iris dataset.
Split the dataset into training and testing sets.
Train a Decision Tree Classifier on the training data.
Evaluate the model using accuracy and a detailed classification report.
Predict the species of a new sample.

Examples

Output

Running the script will produce an output similar to:

Model Accuracy: 0.98

Classification Report:
              precision    recall  f1-score   support

    setosa       1.00      1.00      1.00        16
    versicolor   1.00      0.92      0.96        12
    virginica    0.92      1.00      0.96        12

    accuracy                           0.98        40
   macro avg       0.98      0.98      0.98        40
weighted avg       0.98      0.98      0.98        40

Predicted Species: setosa

Predicting New Samples

To predict the species of a new iris flower, you can modify the new_sample variable in the script:

new_sample = [[5.0, 3.6, 1.4, 0.2]]  # Example features: sepal length, sepal width, petal length, petal width

Run the script again to see the predicted species.
