A2DEUpdateable (3.7)


A2DE achieves highly accurate classification by averaging over all of a small space of alternative naive-Bayes-like models that have weaker (and hence less detrimental) independence assumptions than naive Bayes

The resulting algorithm is computationally efficient while delivering highly accurate classification on many learning tasks.

Use m-estimate for smoothing base probability estimates witha default of 1 (m value can changed via option -M).Default mode is non-incremental that is probabilites are computed at learning time.

An incremental version can be used via option -I.

Default frequency limit set to 1.
