Recommendations for high-quality datasets for AI/Deep Learning training?

Question

Body

I am a Software Engineering student currently working on Deep Learning projects, specifically focusing on Computer Vision and NLP (Next-Word Prediction).

Besides the well-known platforms like Kaggle, what are your go-to sources for finding high-quality and reliable datasets? I am looking for platforms that offer:

Labeled images for Object Detection

Text corpora for Language Models

Clean datasets for general Machine Learning tasks

Any recommendations or hidden gems would be greatly appreciated

Hi @Yigtwxx

Thanks for being a part of the GitHub Community, we're glad you're here!

If you're looking for help for this specific topic, you might want to try asking for help somewhere that focuses on this project, such as this one. It's possible that another GitHub user might have run into this same issue and can help, but the GitHub Community on Discussions focuses primarily on topics related to GitHub itself or collaboration on project development and ideas. We want to make sure you’re getting the best support you can, but this space may not be the right place for this particular topic.

Best of luck!

This is a great one for you to answer! The question is directly about ML datasets — something you know well from your deep-learning and machine-learning repos.
Post this answer in that discussion:

Great question! Here are my go-to sources beyond Kaggle:
For Labeled Images (Object Detection / Computer Vision):

Roboflow Universe — thousands of labeled CV datasets, many ready for YOLO
Open Images Dataset (Google) — massive labeled image dataset with bounding boxes
COCO Dataset — industry standard for object detection and segmentation
ImageNet — best for classification tasks
Supervisely — good for custom annotation + pre-labeled datasets

For Text / NLP (Language Models, Next-Word Prediction):

HuggingFace Datasets — best single source for NLP, thousands of text corpora
Common Crawl — massive web text corpus used to train GPT-style models
The Pile — diverse, high quality text dataset for LLM training
OpenWebText — open reproduction of GPT-2 training data

For General Clean ML Datasets:

UCI ML Repository — classic, clean, well-documented datasets
Papers With Code — datasets linked directly to research papers with benchmarks
Google Dataset Search — search engine specifically for datasets
AWS Open Data Registry — large scale datasets hosted free on S3

Hidden gems:

Zenodo — research datasets from universities, very high quality
data.world — collaborative data platform with clean structured datasets

For your Next-Word Prediction project specifically, I'd start with HuggingFace Datasets — filter by language modeling task and you'll find exactly what you need instantly.
Hope this helps! 🚀
