If you’re new to classification, a decision tree is probably your best starting point. It will give you a clear visual, and it’s ideal to get a grasp on what classification is actually doing. K-NN comes in a close second; Although the math behind it is a little daunting, you can still create a visual of the nearest neighbor process to understand the process. Finally, you’ll want to dig into Naive Bayes. The math is complex, but the result is a process that’s highly accurate and fast—especially when you’re dealing with Big Data., A myriad of options exist for classification. In general, there isn’t a single “best” option for every situation. That said, three popular classification methods— Decision Trees, k-NN & Naive Bayes—can be tweaked for practically every situation. Overview Naive Bayes and K-NN, are both examples of supervised learning (where the data comes already labeled). Decision trees are easy to , 1) To favour decision trees, have only a few attributes determine the correct answer, with all the others useless distractions. 2) To favour Naive Bayes, construct 2n+1 attributes by choosing at random either n 1s and n+1 -1s or n+1 1s and n -1s and assigning them to attributes at random..
Like the Naive Bayes classifier, decision trees require a state of attributes and output a decision. To clarify some confusion, “decisions” and “classes” are simply jargon used in different areas but are essentially the same., Just like KNN and Naive Bayes, Decision Tree is able to handle multiclass problems. However, Decision Tree tends to overfit data with a large number of features. Mechanisms such as pruning, setting the minimum number of samples required at a leaf node, or setting the maximum depth of the tree are necessary to avoid this problem., Comparing QDA to Naive Bayes is interesting. Although they get similar performance for the first dataset, I would argue that the naive bayes classifier is much better as it is much more confident for its classification., As a part of this study, we examine how accurate different classification algorithms are on diverse datasets. On five different datasets, four classification models are compared: Decision tree, SVM, Naive Bayesian, and K-nearest neighbor. The Naive Bayesian algorithm is proven to be the most effective among other algorithms., Overview Naive Bayes and K-NN, are both examples of supervised learning (where the data comes already labeled). Decision trees are easy to use for small amounts of classes., Classification algorithms have a wide range of applications like Customer Target Marketing, Medical Disease Diagnosis, Social Network Analysis, Credit Card Rating, Artificial Intelligence, and Document Categorization etc. Several major kinds of classification techniques are K-Nearest Neighbor classifier, Naive Bayes, and Decision Trees..
