Recognition of handwritten digits and also data compression projects done. (*Note: digit recognition project has some modification compared to the orginal course project code in order to improve performance) Concepts: This repository contains mini projects on:

1. Linear Regression
2. Logistic Regression
3. Neural Network
4. Backpropagation Algorithm
5. Understand handwritten numbers from 0-9
6. Error Analysis and Learning Curve
7. Precision/Recall and F1 score
8. SVM (linear and Gaussian Kernel)
9. Spam Classifier
10. k-means
11. Principal Component Analysis
12. Image and Data compression
13. application of PCA to dimension reduction to help to visualize data and make supervised learning algorithm run faster.
14. Anomaly Detection along with Gaussian Distribution
15. Multivariate Gaussian Distribution
16. Recommender Systems
17. Collaborative Filtering
