How to Download Big Data for Data Science Projects Free of Cost

Check some top popular websites to download the free datasets available for various areas such as natural language processing, computer vision, and domain-specific sciences. So, if you are in Machine learning, Artificial intelligence, or other Data science projects, this article may be beneficial for you.

Nowadays, the world is becoming datacentric in all means and every big/small company over the globe is investing huge amounts of money to get the right kind of data to make their work easy. When I say data it means any kind of data starting from user information who are interested in purchasing a BMW to data regarding the number of dogs present in some city say, New York.

This data plays a pivotal role in the revenue generation of the company by helping the stakeholders in a variety of ways like getting to know about the market scenario, getting to know about their competitors, etc. Due to this great hunt, a new stream of engineering has also evolved a lot and is supposed to take over the world in the coming days. This engineering/technology is called Artificial Intelligence.

Companies are hiring AI engineers/ML engineers/Data Scientists to handle the relevant data and generate meaningful insights out of it and in turn, the engineers are getting highly paid towards their contribution. But, have you ever wondered that how tough it is in actuality to get millions of data for your use case and then preprocess the same. A lot of time is expended in gathering information and this leads to the spending of huge amounts of money.

For a Big M company it is not a problem but for a small one like any fintech startup spending huge amounts of money at the beginning becomes a challenge. Well, if you are a learner or just working on some project where there is a requirement to test a huge amount of data then here in this article we have given some sources and that too at free of cost. So, let’s see some of those websites and use their open-source datasets for our use case.

Best Websites providing free Datasets to Download

1. Kaggle

This is a very known place in the AI world for getting any kind of data you want. The platform is owned by Google and provides you millions of datasets starting from small(MB’s) to large(GB’s). All you need to do is just register your account with Kaggle and that’s it. After the registration, you are free to download any type of data you want.
