A Beginner’s Guide to Machine Learning: Types and Examples Explained

What is Machine learning?

The field of machine learning is an exciting branch of Artificial Intelligence, and we are surrounded by it every day. The power of machine learning is being harnessed in new ways, such as Facebook recommending articles in your feed. Computer programs can automatically perform tasks via predictions and detections thanks to this amazing technology, which allows computers to learn and improve from their experiences.

More data input into a machine helps the algorithms teach the computer, which improves its output. Amazon Echo will play the station you have played most often when you ask Alexa to play your favorite music station. With Alexa, you can skip songs, adjust the volume, and do many more things to enhance your listening experience. All of this is made possible by Machine Learning and Artificial Intelligence’s rapid advancement.

Machine Learning Examples

Following are the examples we explained of machine learning.

Speech recognition

Text can be translated into speech using machine learning. It is possible to convert live voice and recorded speech into text files using certain software applications. As well as time-frequency bands, speech can be segmented based on its intensities. Google Home and Amazon Alexa are some of the most popular devices that use speech recognition software.

Medical diagnosis

Disease diagnosis can be assisted by machine learning. The use of chatbots with speech recognition capabilities by physicians for diagnosing symptoms has become increasingly common. With the help of facial recognition software and machine learning, it is possible to scan patient photos and identify phenotypes associated with rare genetic diseases.

Statistical arbitrage

The concept of arbitrage is used in finance to manage a large volume of securities through automated trading strategies. Using economic variables and correlations, the strategy analyzes a set of securities. In order to enhance the results of the arbitrage strategy, machine learning is used to optimise the strategy.

Predictive analytics

Using machine learning, data can be classified into groups based on the rules that are established by analysts to define these groups. The analysts can calculate the probability of a fault occurring after the classification has been completed. In the world of machine learning, predictive analytics is one of the most promising applications. This method is applicable to everything, from product development to real estate pricing; it is applicable to everything.


Structured information can be extracted from unstructured data using machine learning. Customers provide huge amounts of data to organizations. Predictive analytics tools use machine learning algorithms to annotate datasets. There is usually a great deal of tedious work involved in these processes. As a result, machine learning is able to track and extract information in order to collect billions of samples of data. 

Machine Learning Types

The main areas of machine learning are supervised learning and unsupervised learning, which are both complexes. There are various forms of data, each with its own purpose and action. In machine learning, supervised learning accounts for 70 percent, while unsupervised learning accounts for 10-20 percent. Reinforcement learning occupies the rest of the time.

Supervised Learning

We train our algorithm based on known or labeled data in supervised learning. Since the data is known, the learning is supervised, that is, directed toward success. During the training of the model, the input data is processed by the Machine Learning algorithm. Using unknown data, you can train the model based on the known data and get a new result.

Unsupervised Learning

Training data in unsupervised learning are unknown and unlabeled, which means they have never been examined before. The unsupervised term originates from the inability to guide the input to the algorithm without known data. The model is trained by feeding this data into the machine learning algorithm. To find the desired response, the trained model searches for patterns. A machine is often used here to break code rather than a human mind, as with the Enigma machine.

Reinforcement Learning

Through trial and error, the algorithm determines what action to take based on the outcome of trial and error. Reinforcement learning is made up of three major components: the agent, the environment, and the actions. Learning occurs when the agent interacts with the environment, making decisions, and taking actions. The agent learns reinforcement by selecting actions that maximize their expected reward over time. An agent can achieve this most easily when he or she is working within a sound policy framework.
