Datasets for Machine Learning – Free to use

In this blog post, we will look at freely available datasets for Machine Learning that can be used for learning and various analysis and predictions.

Machine Learning is one of the biggest game-changer in the technological world. The technology has a huge potential and it is findings its place in the application and services we use in today’s world. Machine Learning depends upon the algorithms and these algorithms need data in order to find patterns and perform predictions. In short, data is the bread and butter for these algorithms. Let us start with a few things to consider before using datasets for machine learning tasks.

Fews things to consider for a dataset

The quality of the dataset directly determines the accuracy of the prediction of the Machine Learning model. The quality determination depends upon a number of factors and may vary from project to project and on what your application is trying to achieve, here are a few common factors to consider before searching a dataset. There are many others as well.

  • Metadata: describes the structure of the dataset and provides important information like what data types are being used, what and how is data arranged and how to understand them.
  • Availability: This is another important aspect to consider as it defines how the data will be available on a timely basis and how frequently it is updated.
  • Accuracy: This factor determines that the data represented in the dataset is having authentic values as given by the source and using them will not cause any ambiguity. Data are consistent with as per the metadata defined and maintains its content integrity.
  • Source: The source of the dataset is another important criterion to look upon, it validates the reliability, consistency and time availability of the dataset.

Datasets for Machine Learning


This is one of the best sources for finding datasets for learning purposes. Kaggle contains a variety of real-life datasets of all different formats and sizes submitted by its members. The good part of Kaggle is, you have discussions, tasks are created around it for which you can provide a solution and even find solutions provided by other members. The various analysis provided by data scientists is also available.

Datasets for Machine :

Google dataset Search Engine

If you would like to search and find your dataset using a search engine then Google Dataset Search is the best place to look for, the search engine has millions of dataset already indexed and the best of all is that you can apply filters on the search to find out the type of dataset you are interested in. You can look at table-based, text-based, or image-based datasets.

Github Awesome Public Datasets

This is another great place to find a huge list of categorized high-quality datasets on GitHub. The list contains dataset lists collected from various blogs, user responses, and answers provided by users. For me, this is one of the great places to start and look for datasets.

Amazon Review Dataset

The dataset contains 233 million Amazon customer reviews, it is a great source for customer’s sentiment analysis. The data is well categorized based on product types like Automotive, Books, Amazon Fashion, etc. The dataset is also categorized into smaller subsets for experimentation containing only the ratings.
