What is the difference between Bayes and naive Bayes?

3 Answers. Naive Bayes assumes conditional independence, P(X|Y,Z)=P(X|Z), Whereas more general Bayes Nets (sometimes called Bayesian Belief Networks) will allow the user to specify which attributes are, in fact, conditionally independent.

How do I decide which model to use?

How to Choose a Machine Learning Model – Some GuidelinesCollect data.Check for anomalies, missing data and clean the data.Perform statistical analysis and initial visualization.Build models.Check the accuracy.Present the results.

Can naive Bayes be used for multiclass classification?

Pros: It is easy and fast to predict class of test data set. It also perform well in multi class prediction. When assumption of independence holds, a Naive Bayes classifier performs better compare to other models like logistic regression and you need less training data.

Which algorithm is most suitable for binary classification?

Popular algorithms that can be used for binary classification include:Logistic Regression.k-Nearest Neighbors.Decision Trees.Support Vector Machine.Naive Bayes.

Which model is widely used for classification?

The periodic table is the most widely used and accepted classification table worldwide.

Can SVM be used for multiclass classification?

Multiclass Classification using Support Vector Machine In its most simple type SVM are applied on binary classification, dividing data points either in 1 or 0. For multiclass classification, the same principle is utilized. … It basically divides the data points in class x and rest.
