Naive Bayes is a simple technique for constructing classifiers: models that assign class labels to problem instances, represented as vectors of feature values, where the class labels are drawn from some finite set. It is…
In pattern recognition, the k-Nearest Neighbors algorithm (or k-NN for short) is a non-parametric method used for classification and regression. In both cases, the input consists of the k closest training examples in the feature space. The output depends on whether k-NN is used for classification or regression
Logistic regression was developed by statistician David Cox in 1958. The binary logistic model is used to estimate the probability of a binary response based on one or more predictor (or independent) variables (features). It allows one to say that the presence of a risk factor increases the odds of a given outcome by a specific factor. The model is a direct probability model and not a classifier.

In this article, we will show you how to install R Studio and create your first R Program. We will also touch concepts like Knit and Markdown files.
How am I going to be successful in this Artificial Intelligence world? What should I learn? Should I learn R , Python or Java / Scala ? Do I need a Phd to become successful? In this article, we are going to discuss soft-skills and hard skills required to be successful in this new world.
We started by saying – There is an APP for that. Now there is a new Buzz – Is there a BOT for that?
Venture Beat published an Article on August 11th this year touching upon BOTS landscape.
In machine learning, support vector machines (SVMs, also support vector networks) are supervised learning models with associated learning algorithms that analyze data used for classification and regression analysis.
In this article, we will discuss various solutions Machine Learning provides. We will provide example for each of the solutions.
For example – Product Recommendation System.
A decision tree is a decision support tool that uses a tree-like graph or model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. It is one way to display an algorithm.
KNN is a simple concept: define some distance metric between the items in your dataset, and find the K closest items. You can then use those items to predict some property of a test item, by having them somehow “vote” on it.
