Machine Learning Practice

This repository serves as a refresher for practicing widely used Machine Learning (ML) algorithms. It includes Python implementations for various ML models, ranging from basic to advanced, using diverse datasets.

Introduction

This repository is designed to reinforce concepts and skills in Machine Learning by working on hands-on examples with Python. It includes code for:

• Basic Python concepts.
• Data preprocessing.
• Supervised and unsupervised ML algorithms.
• Evaluating models and tuning hyperparameters.

Prerequisites

Before running the code, ensure you have:

• Python 3.7+
• Libraries such as numpy, pandas, scikit-learn, matplotlib, and seaborn.

Install dependencies using:

pip install -r requirements.txt

ML Models Covered

1. Linear Regression

   • Predicting house prices using the Boston Housing dataset.

2. Logistic Regression

   • Classifying diabetes using the Pima Indians Diabetes dataset.

3. Decision Trees

   • Predicting survival on the Titanic dataset.

4. Random Forest

   • Feature importance and classification on a custom dataset.

5. K-Nearest Neighbors (KNN)

   • Classification of the Iris dataset.

6. Support Vector Machines (SVM)

   • Classification using a two-class synthetic dataset.

7. K-Means Clustering
