DeepLearning.AI has launched a new course titled "Retrieval Optimization: From Tokenization to Vector Quantization" in collaboration with Qdrant, aimed at helping developers and data enthusiasts enhance vector search capabilities in their applications. Led by Qdrant’s Kacper Łukawski, this one-hour, beginner-friendly, and free course offers an introduction to key concepts such as tokenization techniques, including Byte-Pair Encoding, WordPiece, and Unigram, and explores how these affect the quality of search. Participants will also learn about optimizing search through adjustments to HNSW parameters and vector quantization, equipping them with practical skills in building and optimizing Retrieval-Augmented Generation (RAG) applications. This course is particularly beneficial for those with basic Python knowledge and is accessible online through the DeepLearning.AI platform.
