This document outlines the roadmap and agenda for a machine learning meetup covering clustering algorithms. The meetup will include sessions on k-means clustering, DBSCAN, hierarchical clustering, mean shift, spectral clustering and dimension reduction. Spectral clustering will be covered in two sessions focusing on the mathematical foundations and applications in computer vision. The meetup aims to provide an overview of machine learning techniques and their applications in domains such as business analytics, recommendation systems, natural language processing and the energy industry.
