In conclusion, … Webb1 dec. 2008 · As an important contribution to this topic, based on their theoretical and empirical comparisons between the naïve Bayes classifier and linear logistic regression, Ng and Jordan (NIPS 841–848, 2001) claimed that there exist two distinct regimes of performance between the generative and discriminative classifiers with regard to the …
Webb1 okt. 2024 · Generative models have been used as adversarially robust classifiers on simple datasets such as MNIST, but this robustness has not been observed on more … Webb10 jan. 2024 · Recall that we are interested in the conditional probability of each input variable. This means we need one distribution for each of the input variables, and one set of distributions for each of the class labels, or four distributions in total. First, we must split the data into groups of samples for each of the class labels.
