A Simple Example: Naive Bayes Classifier One common machine learning algorithm is the Naive Bayes classifier, which is used for filtering spam emails. It keeps messages like “Nigerian Prince Needs Monetary Assistance!” out of your inbox. So how does it work? Every time you click the “Mark...

Google’s search algorithm is easily one of the most influential technologies ever created. But what is it and how does it work? Enterprise Content Marketing Strategy To Drive Growth Enterprise content marketing can drive tons of leads, conversions, and revenue. Here's how to build momentum on...
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...
There are many other other online courses you can take after this one (see My answer to What is the best MOOC to get started in Machine Learning?)but at this point you are mostly ready to go to the next step. Implement an algorithm My recommended next step is the following. Get a ...
Last time, I went through some basics of how naive Bayes algorithm works, and the logic behind it, and implemented the classifier myself, as well as using the NLTK. That’s great and all, and hopefully people reading it got a better understanding of what was going on, and possibly how...
Generally, when working on a machine learning problem you cannot know which algorithm will be the best for your problem beforehand. If you had enough information to know which algorithm would achieve the best performance, you probably would not be doing applied machine learning. You would be doin...
How does sentiment analysis work? In data science lingo, sentiment analysis is a classification problem: the algorithm is presented with pieces of text that need to be classified as positive, negative, or neutral. The problem is usually tackled with the help of Natural Language Processing (NLP)...

However, the Naive Bayes algorithm achieves an F-Measure score of 93% for the same category. Similarly for the Collaborator category the Naive Bayes model achieved better results compared to the Random Forest model. Both categories can contain similar information, i.e., the name of other ...
