Talk #1 "Why Delta Lake changes everything?" Let's learn how Delta Lake transforms chaotic data swaps into high-performing, reliable ecosystems. In this session, we’ll explore how Delta Lake brings ACID (Atomicity, Consistency, Isolation, Durability) transactions, schema enforcement, and time travel to your data architecture—without locking you into a proprietary stack. Whether you’re handling streaming data, prepping for machine learning, or ensuring GDPR compliance, Delta Lake has you covered.
Talk #2 "A Multi-layered Approach to RAG Hallucination Prevention" This presentation offers practical insights for designing and implementing a robust, factually-grounded Retrieval Augmented Generation system through our multi-layered hallucination prevention methodology. The approach combines five synergistic techniques: advanced query rewriting with Hypothetical Document Embeddings and key term extraction, LLM-powered semantic filtering, automated chain of thought generation, a specialized Guardrails Agent for response oversight, and an agentic dispatcher for iterative answer refinement.
