In this algorithm, we split the population into two or more homogeneous sets. For more details, you can read: The best way to understand how decision tree works, is to play Jezzball — a classic game from Microsoft image below. Essentially, you have a room with moving walls and you need to create walls such that maximum area gets cleared off with out the balls.

So Yavar has used K-nearest neighbours for calculating the likelihood. How correct is that? If it is, what are some other methods to calculate the likelihood? I read about Gaussian Naive bayes where the likelihood is gaussian.

How can that be explained? If you don't know the distribution and thus the probability densitiy of such distribution, you have to somehow find it.

This can be done via kNN or Kernels. I think there are some things missing. You can check out this presentation though. Feb 9 '17 at 9: The reason I'm posting is that is the accepted answer has many elements of k-NN k-nearest neighborsa different algorithm.

Both k-NN and NaiveBayes are classification algorithms. Conceptually, k-NN uses the idea of "nearness" to classify new entities. By contrast, in NaiveBayes, the concept of 'probability' is used to classify new entities. Since the question is about Naive Bayes, here's how I'd describe the ideas and steps to someone.

I'll try to do it with as few equations and in plain English as much as possible. If you are familiar with these concepts, skip to the section titled Getting to Naive Bayes' Conditional Probability in plain English: What is the probability that something will happen, given that something else has already happened.

Let's say that there is some Outcome O. And some Evidence E.

From the way these probabilities are defined: Let say we have a collection of US Senators. Senators could be Democrats or Republicans.

They are also either male or female. If we select one senator completely randomly, what is the probability that this person is a female Democrat? Conditional Probability can help us answer that. Often, we know how frequently some particular evidence is observed, given a known outcome.Building Random Forest Algorithm in Python.

In the Introductory article about random forest algorithm, we addressed how the random forest algorithm works with real life initiativeblog.com continues to that, In this article we are going to build the random forest algorithm in python with the help of one of the best Python machine learning library Scikit-Learn.

Given two natural numbers, k>r>0, a training example is called a (k,r)NN class-outlier if its k nearest neighbors include more than r examples of other classes. CNN for data reduction. Condensed nearest neighbor (CNN, the Hart algorithm) is an algorithm designed to .

I realize that this is an old question, with an established answer. The reason I'm posting is that is the accepted answer has many elements of k-NN (k-nearest neighbors), a different initiativeblog.com k-NN and NaiveBayes are classification algorithms. This module introduces basic machine learning concepts, tasks, and workflow using an example classification problem based on the K-nearest neighbors method, and implemented using the .

Deep Blue was the first computer that won a chess world championship. That was , and it took 20 years until another program, AlphaGo, could defeat the best human Go initiativeblog.com Blue was a model based system with hardwired chess rules.

AlphaGo is a data-mining system, a deep neural network trained with thousands of Go games. In this post, we take a tour of the most popular machine learning algorithms.

It is useful to tour the main algorithms in the field to get a feeling of what methods are available. There are so many algorithms available that it can feel overwhelming when algorithm names are thrown around and you are.
