Beschreibung

What if you could explain ChatGPT using only a dog, some audiobooks, and a stick? Joey Yudelson joins Sam and Shifra to break down how large language models actually work, no PhD required. From next-word prediction to reinforcement learning, this one will make you feel like you actually get it. We talk about: - How LLMs learn to "speak human" by predicting the next word - What reinforcement learning actually does (and why your model needs a stick sometimes) - Why RLHF is basically dog training at a bazillion scale - Spurious correlations and how models learn the wrong lessons - What it really means when an AI "has a persona" Follow Saturdata, your favorite weekend data podcast: Spotify: https://open.spotify.com/show/5QolhKm1jDZzVuHO0S9ZBo?si=910efb23833f4fc1 [https://open.spotify.com/show/5QolhKm1jDZzVuHO0S9ZBo?si=910efb23833f4fc1] LinkedIn: https://www.linkedin.com/company/saturdata [https://www.linkedin.com/company/saturdata] Instagram: @SaturdataPod #Saturdata #MachineLearning #ChatGPT #LLM

We're making up AI as we go | Saturdata with Joey Yudelson

What happens when you train an evil AI and it just lies really confidently? Joey Yudelson (https://www.linkedin.com/in/joseph-yudelson/ [https://www.linkedin.com/in/joseph-yudelson/]), AI safety researcher at Redwood Research, joins Sam and Shifra to break down why 300 people standing between us and a catastrophic AI future might not be enough, and what data folks can actually do about it. We talk about: - Taxonomies of AI risk (silly vs. not silly, yes this is a real framework) - Why the evil AI wrote 30 paragraphs insisting its buggy code was perfect - Global AI regulation and who's actually doing a good job (hint: it's the EU) - How to use Claude agents like a multiplayer cheat code - Why you personally could make a dent in AI safety research Follow Saturdata, your favorite weekend data podcast Spotify: https://open.spotify.com/show/5QolhKm1jDZzVuHO0S9ZBo?si=910efb23833f4fc1 [https://open.spotify.com/show/5QolhKm1jDZzVuHO0S9ZBo?si=910efb23833f4fc1] LinkedIn: https://www.linkedin.com/company/saturdata [https://www.linkedin.com/company/saturdata] Instagram: @SaturdataPod #Saturdata #AISafety #DataScience #MachineLearning Chapters: 0:00 - Intro 0:57 - Joey's origin story: from high school Yudkowsky reader to full-time AI safety researcher 3:42 - A guided tour of the AI safety landscape 6:14 - Where Joey fits in the puzzle: model organisms and misalignment research 7:28 - The evil AI that wrote 30 paragraphs insisting its buggy code was perfect 10:55 - Deep in the lab vs. everyday AI user: how different are they really? 13:42 - The knowledge lag: why comedians are still calling AI "smart autocomplete" 17:24 - Taxonomies of risk: silly vs. not silly (yes, water use is on the table) 22:02 - Being a responsible AI user: what data folks can actually do 28:32 - How LLMs actually work, explained with a very talented dog named Jeeves 33:11 - Joey's lifelong vendetta against SQL (and how he gets away with it) 36:59 - Three rules for getting real value out of AI agents without losing your mind 42:48 - Why you personally could make a dent in AI safety (and the case for Talmudic AI research) 45:20 - Takeaways and outro
