3 hours ago Scikit Learn - KNN Learning, k-NN (k-Nearest Neighbor), one of the simplest machine learning algorithms, is non-parametric and lazy in nature. Lazy or instance-based learning means that for the purpose of model generation, it does not require any training data points and whole training data is used in the testing phase.

Frequently Asked Questions

How to train the kNN algorithm with scikit-learn?

It is extremely straight forward to train the KNN algorithm and make predictions with it, especially when using Scikit-Learn. The first step is to import the KNeighborsClassifier class from the sklearn.neighbors library. In the second line, this class is initialized with one parameter, i.e. n_neigbours. This is basically the value for the K.

Where can I learn about machine learning using scikit-learn?

Scikit-learn is a free machine learning library for the Python programming language. We have released a full course on the freeCodeCamp.org YouTube channel that will teach you about machine learning using scikit-learn (also known as sklearn). First you will learn about the basics of machine learning and scikit-learn.

What are the prerequisites to learn scikit?

Scikit is more for creating and building models, so one must have basic understanding of various supervised and unsupervised models. Model evaluation metrics, underlying mathematical calculations. One should also be comfortable with the basics of python programming, and other commonly used libraries. 3. Download and Install Scikit Learn

What are the classification models supported by scikit-learn?

Scikit learn has support for many classification models, here we would go ahead and work with Logistic, Random Forest, KNN, Naive bayes. Decision trees and Boosting algorithms. In scikit these are in form of target and features.
