WitrynaDefinition. Unlike generative modelling, which studies the joint probability (,), discriminative modeling studies the ( ) or maps the given unobserved variable (target) to a class label dependent on the observed variables (training samples).

Witryna18 mar 2024 · System logs are almost the only data that records system operation information, so they play an important role in anomaly analysis, intrusion detection, and situational awareness. However, it is still a challenge to obtain effective data from massive system logs. On the one hand, system logs are unstructured data, and, on … WitrynaSo KNN doesn't fit nicely with generative models. One may argue that KNN is a discriminative model because we can draw discriminant boundary for classification, or we can compute the posterior P(Ci/x). But all these are true in the case of generative … Witryna25 kwi 2024 · Naive Bayes classification is a generative model. This is because it uses knowledge (or assumptions) about the underlying probability distributions that generate the data being analyzed—it is capable of generating new data points..
