WebNaive Bayes is a widely employed eﬁective and e–cient approach for classiﬂ-cation learning, in which the class label y(x) of a test instance x is evaluated by y(x) = argmax c h P(c)£ Qd i=1 P(xi j c) i; where P(c) is a class probability, d is the number of attributes, xi is the i’th attribute of instance x, and P(xi j c) is WebBayesian inference techniques are used to solve the GPPM–DS prob- lem (Section 2.3). Speciﬁcally, we determine a lower bound for the generally intractable model posterior. We resort to optimizing an ap- proximation of the marginal function, and imposing sparsity constraints on the model parameters.
