Deep dives
Interpretability in Language Models
The podcast episode delves into Peter Hossie's research areas during his PhD, highlighting three key focuses. Firstly, interpretability deals with understanding language models' internal reasoning processes, emphasizing the importance of trust in these models' responses. Secondly, model editing aims to update factual knowledge within language models, revealing challenges in pinpointing where information is stored within the model. Lastly, scalable oversight addresses supervising AI systems as they improve at tasks, where understanding model interpretability can enhance overall safety measures.
Challenges in Model Editing
Amid discussions about model editing, the podcast uncovers complexities in identifying where facts are stored within language models. Contradicting traditional beliefs that knowledge is stored in specific layers or components, the research reveals unintuitive methods required for effective model editing. The narrative shifts from pinpointing exact storage locations to comprehending the broader mechanisms at play within neural networks.
Surgical Editing and Localization
In exploring methods like Rome for surgical model editing, the podcast delves into dissecting how precise edits affect model behavior. By investigating how interventions alter neural network behavior and information storage, insights emerge about the complexity of localizing knowledge within models. Such surgical edits challenge conventional beliefs on information storage and retrieval, shedding light on the nuanced interactions within neural networks.
Easy to Hard Generalization and Model Oversight
The episode punctuates the concept of easy to hard generalization in training language models, showcasing how training on simpler data effectively impacts model performance on complex tasks. This notion extends to oversight and safety concerns, suggesting that easy supervision can lead to accurate decision-making in diverse domains without extensive data collection. The discussion emphasizes task specification and domain agnostic prompts as crucial elements for enhancing model performance and generalization across various domains.
Today we're joined by Peter Hase, a fifth-year PhD student at the University of North Carolina NLP lab. We discuss "scalable oversight", and the importance of developing a deeper understanding of how large neural networks make decisions. We learn how matrices are probed by interpretability researchers, and explore the two schools of thought regarding how LLMs store knowledge. Finally, we discuss the importance of deleting sensitive information from model weights, and how "easy-to-hard generalization" could increase the risk of releasing open-source foundation models.
