In this two-part presentation Lionel demonstrates two different clustering techniques using the Titanic dataset.
Using Clustering for Preprocessing: Clustering can be an efficient approach to dimensionality reduction, in particular as a preprocessing step before a supervised learning algorithm.
Using clustering for semi-supervised learning: Another use case for clustering is in semi-supervised learning, when we have plenty of unlabeled instances and very few labeled instances.
