Data Science and Machine Learning (Theory and Projects) A to Z - Building Machine Learning Model from Scratch: K-Means C

The video tutorial explains the K-means clustering algorithm, a popular method in unsupervised learning. It covers the basic concept of clustering without target labels, the process of selecting initial means, and the iterative process of assigning data points to clusters and recalculating means. The tutorial also discusses convergence criteria and potential challenges, such as dependency on initial mean selection and situations where the algorithm may not converge. The video concludes with a plan to implement K-means clustering in a Jupyter notebook using synthetic data.
