Unsupervised Learning Training in Marina Bay, Singapore

This training on Unsupervised Learning is designed to introduce participants to the key concepts, algorithms, and techniques used in unsupervised machine learning. Unlike supervised learning, unsupervised learning works with unlabeled data and is used to uncover hidden patterns, structures, or relationships in the data. The course will cover important algorithms such as Clustering (e.g., K-Means, DBSCAN), Dimensionality Reduction (e.g., PCA, t-SNE), and Association Rule Learning. Participants will gain hands-on experience using Python and popular libraries like scikit-learn to solve real-world problems using unsupervised learning.
