This conference talk from MLOps World: Machine Learning in Production features Kacper Łukawski, Senior Developer Advocate at Qdrant, exploring the evolution and capabilities of AI-powered search technologies. Discover how Machine Learning has transformed document retrieval from keyword-based to semantic-based approaches. Learn about the second wave of vector search that enables searching across different modalities without traditional preprocessing like OCR for PDFs. Understand why search quality is fundamental to Retrieval Augmented Generation (RAG) systems and how better retrieval directly impacts AI response quality. Explore advanced concepts including multivector representations such as ColPali during this 30-minute presentation delivered by an experienced software developer, data scientist, and public speaker with a passion for teaching others.
