Title : Neuro-Causal Models
We discuss neuro-causal models, a novel neuro-symbolic model architecture that uses a synthesis of deep generative models and causal graphical models to automatically infer higher level symbolic information from lower level “raw features”, while also allowing for rich relationships among the symbolic variables. Neuro-causal models retain the flexibility of modern deep neural network architectures while simultaneously capturing statistical semantics such as identifiability and causality, which are important to discuss ideal, target representations and their tradeoffs. We provide conditions under which this entire architecture can be recovered uniquely. We also discuss efficient algorithms to learn representations using this architecture, and provide experiments illustrating the algorithms in practice.

Title : Towards Trustworthy Machine Learning
When training and deploying machine learning systems in the real world, we face various types of uncertainty. For example, the available training data may contain insufficient information, label noise, and bias. In this talk, I will give an overview of our research on trustworthy machine learning, including weakly supervised classification, noisy label classification, and transfer learning.
Masashi Sugiyama received his Ph.D. in Computer Science from the Tokyo Institute of Technology in 2001. He has been a professor at the University of Tokyo since 2014, and also the director of the RIKEN Center for Advanced Intelligence Project (AIP) since 2016. He is (co-)author of Machine Learning in Non-Stationary Environments (MIT Press, 2012), Density Ratio Estimation in Machine Learning (Cambridge University Press, 2012), and Machine Learning from Weak Supervision (MIT Press, 2022). In 2022, he received the Award for Science andTechnology from the Japanese Minister of Education, Culture, Sports, Science and Technology. He was program co-chair of the Neural Information Processing Systems (NeurIPS) conference in 2015 and the International Conference on Artificial Intelligence and Statistics (AISTATS) in 2019.
