machine learning classifer - python tutorial

Machine Learning Classifer. Classification is one of the machine learning tasks. So what is classification? It’s something you do all the time, to categorize data. Look at any object and you will instantly know what class it belong to: is it a mug, a tabe or a chair. That is the task of classification and computers can do this (based on data)

machine learning - what is a classifier? - cross validated

1. A classifier can also refer to the field in the dataset which is the dependent variable of a statistical model. For example, in a churn model which predicts if a customer is at-risk of cancelling his/her subscription, the classifier may be a binary 0/1 flag variable in the historical analytical dataset, off of which the model was developed, which signals if the record has churned (1) or not churned (0)

different types of classifiers | machine learning

A classifier is an algorithm that maps the input data to a specific category. Perceptron, Naive Bayes, Decision Tree are few of them. ... Whereas, machine learning models, irrespective of classification or regression give us different results. This is because they work on random simulation when it comes to supervised learning. In the same way

Introduction to Classification. Classification may be defined as the process of predicting class or category from observed values or given data points. The categorized output can have the form such as “Black” or “White” or “spam” or “no spam”. Mathematically, classification is the task of approximating a mapping function (f) from input variables (X) to output variables (Y)
