A dataset is a list of examples — question–answer pairs, labelled images, audio with transcripts. Most of a good model’s quality comes from good data: clean, varied and correct.
Datasets are usually split three ways: training, validation and a final test set.
Example
Hugging Face hosts many Bangla datasets — news, translation and question answering.
