Stream mining
- Core assumption is that training examples can be briefly inspected for a single time only.
- Arrive in a high speed stream and then must be discarded to make room for subsequent examples.
- Algorithm must update its model incrementally as each element is inspected.
- It should ideally be able to apply the model any time between training examples.
- the goal of classification is to produce a model that can predict the class of unlabelled examples by training on examples whose label/class is supplied.
- Data is assumed to have small and fixed no. of columns or attributes/features. This can be thought of as tuples.
- The labels that can be applied to the data are limited, typically less than ten.
