Unsupervised Learning

The video introduces three types of machine learning: supervised, unsupervised, and reinforcement learning, focusing on unsupervised learning. It explains that unsupervised learning deals with unlabeled data, allowing models to discover hidden patterns without supervision. An example involving a baby recognizing pets illustrates this concept. The video highlights the benefits of unsupervised learning, such as finding unknown patterns and easier data acquisition. It also covers two main types of unsupervised learning: clustering, which identifies patterns in data, and association, which finds relationships between variables. The video concludes with a preview of the next topic, K-means clustering.
