Witryna31 sty 2024 · Gaussian Naive Bayes is defined as the process which supports continuous value characteristics. It creates a simple model and fits this model by simply finding the mean and standard deviation of the points. Code: In the following code, we will import some libraries from which to create a Gaussian Naive Bayes classifier. WitrynaNaive Bayes is constrained to the learn the marginal distribution of the data because "naive" assumption. Often times the conditional distribution is useful to make predictions. Given the performance of GaussianNB on that dataset, it might make sense to apply a different classifier that can learn a different decision boundary .
