Principal Components Analysis with numpy: In this project, I will apply PCA to a dataset without using any of the popular machine learning libraries such as scikit-learn and statsmodels. The goal of this document is to have a deeper understanding of the PCA fundamentals using functions just from numpy library.

Shopper Segmentation (Unsupervised Learning): The objective of this project is to segment shoppers from a dataset given. K-Means, Agglomerative and DBSCAN are the three different unsupervised machine learning algorithms used for the project. At the end of the notebook, you can find the evaluation of those models comparing metrics as ARS (Adjusted Rand Score), NMI (Normalized Mutual Information) and Average Score.
