CSE-472: Machine Learning Course Repository

This repository hosts a collection of machine learning assignments and projects created as part of the CSE-472 course. It includes tasks ranging from linear algebra applications, logistic regression, Gaussian Mixture Models, to building a Convolutional Neural Network (CNN) for image recognition.

Assignments Overview

Assignment 1: Linear Algebra for Machine Learning

• Matrix Transformations: Understanding matrix transformations and eigendecomposition through interactive notebooks.
• Eigen Decomposition: Script to perform eigen decomposition on a randomly generated matrix.
• Singular Value Decomposition: Script to calculate the Moore-Penrose Pseudoinverse using SVD.

Assignment 2: Logistic Regression with Bagging

• Simple Logistic Regression: Implementing logistic regression to predict the authenticity of banknotes.
• Logistic Regression with Bagging: Ensembling classifiers using bagging to improve prediction accuracy.

Assignment 3: Gaussian Mixture Model & EM Algorithm

• EM Algorithm: Implementing the Expectation-Maximization algorithm to estimate parameters of Gaussian distributions.
• Visualization: Plotting the estimated Gaussian Mixture Model in 2D space, applying dimensionality reduction for higher-dimensional data.

Assignment 4: CNN for Bangla Handwritten Digit Recognition

• Custom CNN: Implementing CNN architectures from scratch to classify images of handwritten Bangla digits.
• Data Handling: Preprocessing the NumtaDB dataset for model training.
• Performance Optimization: Hyperparameter tuning for model accuracy improvement.
