In this article, we saw more than 20 machine learning datasets that you can use to practice machine learning or data science. Creating a dataset on your own is expensive, so we can use other people’s datasets to get our work done. But we should read the documents of the dataset carefully because some datasets are free, while for some datasets, you have to give credit to the owner as stated by them.
