Building Safe and Robust AI Systems

About the speaker Zico Kolter

Zico Kolter
Zico Kolter is a Professor and Department Head of the Machine Learning Department at Carnegie Mellon University. In addition, he serves as the Chief Technical Advisor to Gray Swan AI, an AI Security company, and serves on the board of OpenAI where he chairs the safety and security committee. His work spans several topics in machine learning, including work in AI safety and robustness, LLM security, the impact of data on models, implicit models, and more.

Abstract

As AI systems become more powerful, it is increasingly important that developers be able to strictly enforce desired policies for the systems. Unfortunately, via techniques such as adversarial attacks, it has traditionally been possible to circumvent model policies, allowing bad actors to manipulate LLMs for unintended and potentially harmful purposes. In this talk, I will highlight several recent directions of work that are making progress in addressing these challenges, including methods for robustness to jailbreaks, safety pre-training, and methods for preventing undesirable model distillation. I will additionally highlight some of the areas I believe to be most crucial for future work in the field.

Framework, Prototype, Definition and Benchmark

About the speaker Song-Chun Zhu

Song-Chun Zhu
Song-Chun Zhu is currently director of Beijing Institute for General Artificial Intelligence (BIGAI) – a non-profit research organization, and Chair Professor at Peking University and Tsinghua University jointly. He is also dean of both School of Intelligence Science and Technology and Institute for Artificial Intelligence at Peking University.    He received Ph.D. degree in computer science from Harvard University in 1996, and after that he worked at Brown, Stanford and UCLA where he established an inter-disciplinary center of Vision, Cognition, Learning and Autonomy (VCLA@UCLA 2002-2020) before he returned to China in late 2020.  He has published 400+ articles in AI areas including CV, Cognition, Robotics, ML, NLP, MAS et al.  His scientific contributions have garnered various recognitions, including the Marr Prize (2003),  twice Marr prize honorary nominations (1999,2007), Sloan Fellowship (2001), J.K. Aggarwal Prize (2008), Helmholtz Test-of-Time Award (2013) , computational modeling prize at CogSci (2017) etc.  He established the Lotus Hill Institute in 2005 to launch large-scale image annotation and pioneered data-driven statistical approaches. He served as general chair for CVPR 2012 and 2019., and led twice the Multi-University Research Initiatives (MURI 2010-2015, 2015-2020) on scene understanding, visual commonsense reasoning and robot autonomy in the US. His research has been pursuing a general unified theory of intelligence.

Abstract

In this talk, I will present a set of work done at the Beijing Institute of General Artificial Intelligence (BIGAI) and Peking University on AGI, which is also called TongAI as the Chinese character ‘Tong’ means ‘general’ and contains the letters ‘A’, ‘G’ and ‘I’. I will start with introducing a digital agent --- a little girl who lives and learns continuously in simulated diverse physics-realistic environments with multi-physics and social interactions. The little girl with a nickname ‘TongTong’ is driven by her own value system with desires and goals which generates plans and actions. Then I will reveal the framework underneath this self-conscious agent with three interconnected components: Cognitive architecture (C), the potential functions (U) representing skills, and the value functions (V). Then we define various AGI systems as points in this joint (C,U,V) –space. This framework represents a paradigm shift from the popular “data-driven” "large data for small tasks" statistical paradigm which we pioneered at Harvard, Brown and UCLA since the early 1990s, to the “value-driven” "small data for large tasks" paradigm which I have been advocating since 2010. Then I will introduce TongTest as new criteria, benchmarks and test platform for measuring the general intelligence of various AI agents on performing multi-modal embodied tasks in complex environments. The TongTest has gone way beyond the Turing test in complexity and integrates results from developmental psychology and anthropology. It assesses the intelligence of TongTong to match a 3-4 years old child. In the talk, I will also show some recent work on humanoid robotics and applications, and discuss the Eastern philosophical thinking what makes humans and intelligence, and how morality and social norm emerge from the CUV framework as a solution to AGI safety.

Abstract

In this talk, we will try to clarify different levels and mechanisms of intelligence from historical, scientific, mathematical, and computational perspective. From the evolution of intelligence in nature, from phylogenetic, to ontogenetic, to societal, and to artificial intelligence, we will try to shed light on how to understand the true nature of the seemingly dramatic advancements in the technologies of machine intelligence in the past decade. We achieve this goal by developing a principled mathematical framework to explain the practice of deep learning from the perspective of compressive data encoding and decoding. This framework not only reveals true nature hence limitations of the current practice and but also provides principled guidelines to develop more complete and more efficient learning architectures and systems. Eventually, we will clarify the difference and relationship between Knowledge and Intelligence, which may guide us to pursue the goal of developing systems with true intelligence.

Training Language Models in Academia: Challenge or Calling?

About the speaker Danqi Chen

Danqi Chen
Danqi Chen is an Associate Professor of Computer Science at Princeton University and co-leads the Princeton NLP Group. She also serves as an Associate Director of Princeton Language and Intelligence (PLI), an initiative focused on developing fundamental research of large AI models. Her recent research centers on training, adapting, and understanding language models (LMs), with an emphasis on making them more accessible to academia. Before joining Princeton, Danqi was a visiting scientist at Facebook AI Research in Seattle. She earned her Ph.D. from Stanford University (2018) and her B.E. from Tsinghua University (2012), both in Computer Science. Her work has been recognized with a Sloan Fellowship, an NSF CAREER Award, a Samsung AI Researcher of the Year Award, and multiple outstanding paper awards from ACL and EMNLP.

Abstract

Training large language models has become a defining pursuit in modern machine learning—one that is almost entirely led by industry, fueled by massive computational resources and guided by scaling laws that reward ever-larger models and datasets. For academic researchers, participating in this space can feel out of reach. The barriers—limited compute, infrastructure, and access to proprietary data—are real and growing. Still, I believe academia has an essential role to play. Even with constraints, there are important scientific questions and meaningful opportunities that academic research is uniquely positioned to tackle. By engaging with the training process itself, we can deepen our understanding of language models and develop novel and efficient approaches that complement large-scale efforts. In this talk, I’ll share my lab’s research efforts over the past two years in both pre-training and post-training of language models under an academic budget. Our work has aimed to better understand training dynamics, innovate within limitations, and release artifacts that benefit the broader research community. I’ll also highlight three areas where academic researchers can make significant contributions: (1) developing small but capable models, (2) understanding and improving training data, and (3) advancing post-training methods on top of open-weight models. My hope is to encourage broader engagement with LM training in academia, and to foster new forms of collaboration between academic and industry research.

Abstract

The pursuit of Artificial Superintelligence (ASI) requires a shift from narrow objective optimization towards embracing Open-Endedness—a research paradigm, pioneered in AI by Stanley, Lehman and Clune, that is focused on systems that generate endless sequences of novel but learnable artifacts. In this talk, I will present our work on large-scale foundation world models that can generate a wide variety of diverse environments that can in turn be used to train more general and robust agents. Furthermore, I will argue that the connection between Open-Endedness and Foundation Models points towards automating innovation itself. This convergence is already yielding practical results, enabling self-referential self-improvement loops for automated prompt engineering, automated red-teaming, and AI debate in Large Language Models, and it hints at a future where AI drives its own discoveries.
