Differentiate between Supervised vs. Unsupervised Learning
In a supervised learning problem, there is an explicit, pre-defined target variable which has known labels.
Unsupervised Learning
What is Clustering?
Clustering is used to partition data set into N distinct groups/clusters. These groups are semantically coherent in nature
What is Unsupervised learning?
Identification of hidden patterns and associations from data is unsupervised learning.
