This is post will share with you the Naive Bayes. What is Naive Bayes? Naive Bayes algorithm: a simple multi-class classification algorithm based on the Bayes theorem. It assumes that features are independent of each other. For a given sample feature X, the probability that a sample belongs ...
1.5. Naive Bayes: Naive Bayes is a probabilistic machine learning algorithm commonly used for classification tasks, especially in natural language processing and text analysis. It’s based on Bayes’ theorem and makes predictions by calculating the probability of a data point belonging to a certain...
The goal of clustering is to partition the dataset in such a way that objects within the same cluster are more similar to each other than to those in other clusters. The similarity or dissimilarity between objects is usually measured using distance metrics, such as Euclidean distance or cosine ...

I think it really depends on your problem though which method to prefer. I can’t find a reference now, but e.g. in classification, naive Bayes converges quicker but has typically a higher error than logistic regression. On small datasets you’d might want to try out naive Bayes, but as...
Naive Bayes is a widely used classification algorithm that's used for tasks involving text classification and large volumes of data. Regression models Regression tasks are different, as they expect the model to produce a numerical relationship between the input and output data. Examples ofregression ...
SVMs vs. naive Bayes Naive Bayes is a generative model of AI. SVM is a discriminative model of AI. Naive Bayes works best for simpler and high-dimensional problems. SVMs excel in more complex scenarios where feature interactions are significant. ...
Naive Bayes: Naive Bayesis a classification algorithm that adopts the principle of class conditional independence from Bayes’ theorem. This means that the presence of one feature does not impact the presence of another in the probability of an outcome, and each predictor has an equal effect on...
Why Naivebayes is called Naive? The Naive Bayes algorithm is called “Naive” because it makes the assumption that the occurrence of a certain feature is independent of the occurrence of other features while in reality, they may be dependent in some way! Bayesian AnalysisData Management Share...
Classification algorithms typically adopt one of two learning strategies: lazy learning or eager learning. These approaches differ fundamentally in how and when the model is built, affecting the algorithm’s flexibility, efficiency, and use cases. While both aim to classify data, they do so with ...
