I was trying to apply some ideas but I need to know is there a dataset like imagenet but smaller that I can try on my personal laptop! i remember that Mr. Jeremy said that he made some thing like that! I wonder if is there a dataset for tasks of nlp, time-series,3d deep learning that Is small that I can try myself and measure my performance, that is also a challenging dataset! I am not a research I just want to play with data and some ideas.
