Machine Learning Examples

Our digital world increasingly relies on technology to drive sustainable growth and innovation for businesses. Data has become a lifeblood for many organizations, with vast of it being generated at an unprecedented rate. A need for sophisticated approaches to derive insights and make accurate predictions is paramount to businesses that aim to remain relevant and leapfrog competition.

This article will delve into popular machine-learning algorithms and their real-world applications.

What is machine learning?

Machine learning is a subfield and application of artificial intelligence that uses advanced mathematical models, algorithms, and statistical techniques to enable computer systems to learn and improve from the data that we feed them. The computer then adjusts its functions even without being explicitly programmed to do so.

Instead of writing code to state actions that the program should take, we write code that provides an algorithm that adapts based on examples of intended behavior. To put this in place, machine learning involves training a model with large amounts of data to recognize patterns or relationships that adapt to business needs to make predictions on their own. The resulting program must “learn” to automate the creation of analytical models so that it continuously improves from the “learned” parameters.

Imagine an online retailer with a high-quality product category that needs to increase its sales and conversions. Based on data around consumer purchase and browsing behavior among other parameters, they can leverage machine learning to optimize recommendations and personalize the customer experience. The results would help businesses identify emerging customer trends, drive customer satisfaction, and adapt to changing markets with ease.

Types of machine learning

Supervised learning

Supervised learning techniques use labeled data to train models. The input is already known and therefore the model needs to project to the respective output. Supervisors play a critical role in guiding the algorithm to learn the underlying patterns and data relationships to map the right output. A supervisor will provide feedback that the model can use to adjust its feature selection and internal parameters to balance the accuracy of the results.

Some of the methods applied to supervised learning include linear regression, random forest,  naïve Bayes, and support vector machine.

Unsupervised learning

In unsupervised learning, an algorithm is trained on unlabeled data and has to find patterns and relationships on its own. By using data points as references, the model can learn to discover meaningful structures and patterns in the observations by extracting generative features or grouping inherent data.

Unsupervised learning is commonly used in applications such as clustering, anomaly detection, pattern recognition, and market segmentation. Some of the algorithms used in unsupervised learning include neural networks, k-means clustering, and probabilistic clustering methods.

Reinforcement learning

Reinforcement learning involves an algorithm that learns to create intelligent systems through trial and error. By receiving feedback in form of penalties and rewards, the algorithm can adapt to changing circumstances and optimize its decision-making. The algorithm interacts with an environment to learn and associate actions to maximize the overall reward over time.

Reinforcement learning is a popular algorithm used in various industries such as gaming and robotics. It involves using feedback from an environment to adjust policies and gradually improve performance. In a gaming scenario, the algorithm seeks to achieve high scores and win games, while avoiding penalties, inefficient moves, or losing a game. Similarly, in a robotics application, the algorithm is rewarded for completing a task or picking and doping objects at the right location while being penalized for dropping objects or failing to complete tasks.
