Types of Tasks in Machine Learning: From Classification to Clustering

Types of Tasks in Machine Learning: From Classification to Clustering

Machine learning is based on algorithms that analyze data, identify patterns and use them to make decisions. Implementation of these tools in business processes allows to increase the efficiency of a company. In this article, we'll look at the main types of tasks, their features and advantages for different industries.

Types of tasks in machine learning are distinguished according to the type of problem to be solved. Each type has its own peculiarities and requires an appropriate approach to choosing algorithms and data processing methods. Classification, regression and clustering are the main ones, and we will consider these types of tasks in more detail below.


Classification is the process of dividing objects into categories based on their characteristics. The main goal of this type of task is to train the model to correctly classify new objects. For example, a classification task can be used to determine if an email is spam based on its content and characteristics.

Objects in classification tasks can be divided into mutually exclusive categories or belong to several categories simultaneously. For example, when classifying news articles by topic, the model will assign several labels to each article. This will allow you to take into account the variety of information contained in each article and ensure accurate grouping.

Classification algorithms are used in a variety of areas, from pattern recognition to fraud detection. In medicine, they can automatically classify X-rays for pathologies, while in finance, they can detect suspicious transactions based on various parameters.


Regression is a type of problem where a model predicts a numerical value based on input data. The purpose of regression is to determine the relationship between certain factors, which can be used to predict targeted changes in the future.

For example, a regression model can be used to predict real estate prices based on various characteristics of a house: its size, location, number of bedrooms and bathrooms, etc.

In retail, regression can help predict demand for certain product categories based on previous sales, weather conditions or advertising costs. This type of task is used in industries where predicting numbers is an important aspect of decision-making.


Clustering is the process of dividing objects into groups or clusters. Objects within one cluster should be similar in some features, but at the same time differ from other groups.

In clustering tasks, the model doesn't have predefined categories, but learns to automatically identify groups of objects based on their characteristics. This type is used for various purposes, from market segmentation to social media analysis.

For example, clustering can help identify groups of users with similar interests or behavior on social media. This data can be used to customize advertising campaigns according to the target audience's characteristics.

Using machine learning models allows companies to predict costs, automate data processing and efficiently allocate resources. The choice of algorithms depends on specific situations and areas that need to be optimized.

Overall, there are many ways to improve your company's performance - from automating routine tasks to implementing production and inventory management systems. Would you like to know more about it?
