Using Machine Learning to Predict Student Performance

WitrynaMany kinds of machine learning algorithms are used to build classifiers. This chapter introduces naive Bayes; the following one introduces logistic regression. These exemplify two ways of doing classification. Generative classifiers like naive Bayes build a model of how a class could generate some input data. Given an ob- Witryna15 sie 2024 · Bayes’ Theorem provides a way that we can calculate the probability of a hypothesis given our prior knowledge. Bayes’ Theorem is stated as: P (h d) = (P (d h) * P (h)) / P (d) Where P (h d) is the probability of hypothesis h given the data d. This is called the posterior probability. cities close to thackerville ok https://robina-int.com
