Website sources for free datasets for machine learning

As a machine learning practitioner, having access to quality datasets is crucial for training and evaluating your models. While there are many sources of paid datasets, finding high-quality free datasets for machine learning can take time and effort.

In this article, we'll explore some of the best places to find free datasets for machine learning and provide tips on evaluating their suitability for your project. Whether you're a beginner or an experienced machine learning engineer, this guide will help you find the free datasets for machine learning that you need to take your projects to the next level.

What is a Dataset?

Datasets are collections of data for analysis. It can be as large or small as you need and contain any information you need to learn from. Datasets are used in many fields, including data science, machine learning, and business research. You can find datasets on the Internet or create your own by collecting data from various sources.

Datasets are often used to train machine learning algorithms and make predictions based on past data. They can also be used for exploratory data analysis (EDA), which involves looking at your data in detail to discover patterns and relationships between different variables.

Google Dataset Search is a tool from Google that helps you find free datasets for machine learning. This is an excellent way to learn about a new dataset and see how it can be used for your next project.

You can search for datasets by topic, source, or language. Additionally, you can filter your search results by file format, license, and data type (publicly available or not).

When you find a dataset that interests you, click on the "View" button to see more information about it. This includes how many times it has been downloaded as well as its size in gigabytes (GB), megabytes (MB), kilobytes (KB), and bytes (B). Additionally, you'll see a brief description of what the dataset contains so that you can decide whether it would suit your needs.
