What Are The Various Types Of Machine Learning?

Machine Learning is a division of artificial intelligence. The fundamental idea of machine learning is to make a machine imitate the learning process of humans with increasing accuracy. From self-driving cars and product recommendations to smartwatches that generate ECG reports instantly, the impact of machine learning is evident across industries and sectors. The global machine learning market shows immense potential, expected to grow 38.8% between 2022-2029. You know what machine learning is, but how many types of machine learning are there? Read on to learn more.

Types of machine learning

There are four types of machine learning algorithms based on the method of learning as discussed below:

Supervised machine learning

In the technique of supervised machine learning, the engineer trains the machine by using a labelled dataset. The machine forecasts an output based on the training.

The labelled dataset contains a specific set of inputs mapped to corresponding outputs. The machine then predicts an output based on the labelled dataset.

The primary objective of supervised machine learning is mapping input variables with output variables. A few supervised machine learning applications are spam filtration, fraud discovery, speech recognition, and risk analysis.

Unsupervised machine learning

Contrary to supervised machine learning, unsupervised machine learning involves training machines with unlabelled datasets. The machine then predicts an output based on the unlabelled dataset without supervision.

The primary goal of unsupervised machine learning is to categorise an unsorted or unlabelled dataset based on differences, patterns, and similarities. The machine works to discover hidden patterns in the input datasets to predict the output.

Unsupervised machine learning is widely used for customer segmentation, product segmentation, recommendation systems and similarity detection.

Semi-supervised machine learning

Semi-supervised machine learning represents a middle ground between supervised and unsupervised machine learning. In semi-supervised machine learning, the engineer trains the machine with a combination of unlabelled and labelled datasets for obtaining the output.

Semi-supervised machine learning aims to use all the available datasets for output prediction. Applications of this type of machine learning include web content classification and image and speech analysis.

Reinforcement machine learning

Reinforcement machine learning operates by a trial-and-error method. The AI-based agent interacts with its environment using a feedback cycle to predict outputs.

In the feedback process, an AI-based agent is automatically deployed to explore a new environment and learn from new situations. Next, the AI-based agent implements improvements based on positive or negative feedback.

Applications of reinforcement learning include autonomous cars, automated medical diagnosis and traffic light control, to name a few.
