Unsupervised Learning Study Notes

The nature of unsupervised learning

The nature of unsupervised learning is the induction of result from data, the process of the induction is described in the form of computer algorithm and implemented by computer program. The induction process differs from discriminative learning process (such as supervised learning) in that no labels is provided to distinguish the correct result from the incorrect ones (hence no positive/negative feedback, no inputs that can be used to adjust the decision process)
