Predictive Analytics I: Data Mining Process, Methods, and Algorithms - Data Mining Concepts and Applications

Q: What are some major data mining methods and algorithms?

The major data mining methods: Prediction Association Segmentation The major data mining algorithms: Decision trees Neural Networks Logistic regression discriminant analysis Support Vector Machines Genetic algorithms

Q: What are the key differences between the major data mining tasks?

Classification : objective is to analyze the historical data stored in a database and automatically generate a model that can predict the future behaviour Clustering : partitions a collection of things. the class labels are unknown (unlike in classification) Associations : objective is discover interesting relationshilps among variables in large databases.
