Classification and clustering (Bayesian)
Clustering is when the computer processes objects through clusters. Please watch http://videolectures.net/mlss09uk_bishop_ibi/ To summarize: a Bayesian network is a graph where nodes represent non-deterministic and sporadic variables. If easy, each value is discrete and takes a limited set of values. If needed, please see the lecture notes on http://ite.gmu.edu/~klaskey/SYST664/SYST664.html
