Unlocking Encoder-Only Transformers (like BERT) for RAG & More 🚀

Encoder-Only Transformers are the backbone for RAG (retrieval augmented generation), sentiment analysis and classification problems, and clustering. This StatQuest covers the main ideas of how these powerhouses do what they do so well, making sure each step is clearly explained!
