What Is Machine Learning – Definition & Examples

Introduction

Machine learning is a field of computer science that uses algorithms to analyze data. It’s used to make predictions and make decisions in applications like search engines, spam filters, product recommendations, medical diagnosis and more.

How machine learning works

Machine learning is a subset of artificial intelligence, which is defined as the ability for computers to learn and make predictions based on data. The process involves using algorithms that analyze data so that computers can learn from it, then make predictions about future events.

Machine learning uses computers to find patterns in large datasets–and then use those patterns to predict future outcomes or classify new instances of similar types of data (such as images). For example: if you have thousands upon thousands of images categorized by their object type (e.g., animal, car), then you could train your computer using machine learning techniques until it was able to accurately identify what kind of object appears in new photos without any help from humans at all!

How machine learning compares to traditional programming

You may have heard the term machine learning and wondered how it compares to traditional programming. Machine learning is a subset of artificial intelligence, which means it uses computers to solve problems and make decisions without being explicitly programmed to do so.

Machine learning algorithms operate by applying statistical techniques on large datasets in order to produce patterns and associations from which they can make predictions about future events (e.g., who will buy my product?). The most popular example of this is Amazon’s recommendation engine–it recommends products based on what other customers bought together with how much they liked each item individually.

Types of machine learning

Machine learning is a type of artificial intelligence that enables computers to learn without being explicitly programmed. Machine learning algorithms build models from data, then make predictions or decisions based on those models.

Machine learning algorithms can be divided into three broad categories: supervised learning, unsupervised learning and reinforcement learning. Supervised machine-learning algorithms are trained with labeled data sets where the inputs and outputs are known; unsupervised machine-learning algorithms are not trained at all; instead they simply make predictions based on what they encounter in their environments or applications; reinforcement learning takes advantage of trial-and-error to improve performance over time

Supervised learning

Supervised learning is a type of machine learning where the algorithm is trained using labeled data. The algorithm learns from the data and then makes predictions based on that knowledge.

A simple example of supervised learning would be predicting if a particular customer will buy your product or not based on their previous behavior, such as purchasing similar products in the past.

Unsupervised learning

Unsupervised learning is used to find patterns and make predictions. It can be used for clustering, anomaly detection, and density estimation.

Unsupervised learning algorithms use data without labels or human input to identify clusters of similar objects or events in a system. For example, consider you have a website with 10 million visitors per day and you want to know what kind of users visit your site during different hours of day (morning vs evening) based on their geographical location or device type – this could be achieved using unsupervised learning algorithms like k-means clustering or PCA(Principal Component Analysis).

In addition to identifying clusters in large datasets without any labels attached to them; unsupervised learning algorithms also play an important role in anomaly detection applications where they analyze data points that fall outside normal behavior patterns identified by supervised machine learning models such as regression trees etc.,

Algorithms for supervised and unsupervised learning

Supervised learning is when you have a set of labeled data. In other words, you know how to classify samples in your dataset into different categories. For example, if you were working with images and wanted to train an algorithm on what dogs look like (and therefore be able to identify new images as either dog or non-dog), then this would be an example of supervised learning because there is already a known label for each image (either dog or non-dog).

Unsupervised learning occurs when there are no labels available for the examples in your dataset–that is, it’s up to the computer program itself to figure out what makes sense based on unlabeled data alone! This may seem challenging but fortunately there are algorithms that can help us achieve this goal:

Machine learning is a field that uses algorithms to analyze data. It’s a subset of artificial intelligence, which means that machine learning can be used in many different applications.

Machine learning is also a type of predictive analytics–it predicts future outcomes based on past performance or behaviors.

Conclusion

Machine learning is a field that uses algorithms to analyze data. It’s a type of artificial intelligence (AI) that can make predictions based on patterns in your data. Machine learning can help you make better decisions, but it also has many other applications like image recognition and voice recognition systems on smartphones.
