Questions

• Where can you find out more about machine learning?

Objectives

• To learn more about machine learning

Other algorithms

There are many other machine learning algorithms that might be suitable for helping to answer your research questions.

The Scikit Learn webpage has a good overview of all the features available in the library.

Ensemble Learning

Ensemble Learning is a technique which combines multiple machine learning algorithms together to improve results. A popular ensemble technique is Random Forest which creates a “forest” of decision trees and then tries to prune it down to the most effective ones. Its a flexible algorithm that can work both as a regression and a classification system. See the article Random Forest Simple Explanation for more information.

Genetic Algorithms

Genetic algorithms are a technique which tries to mimic biological evolution. They will learn to solve a problem through a gradual process of simulated evolution. Each generation is mutated slightly and then evaluated with a fitness function, the fittest “genes” will then be selected for the next generation. Sometimes this is combined with neural networks to change the network’s size structure.

This video shows a genetic algorithm evolving neural networks to play a video game.
