CIS Seminar: “Towards Flexible, Scalable, and Knowledgeable Generative Intelligence”

From language modeling to 3D vision, generative AI has revolutionized nearly every aspect of machine learning. In this talk, I will examine the limitations of the foundation behind many generative AI techniques–autoregressive models. Despite their impressive successes, these token-by-token models face various challenges, including 1). non-flexible computation during generation, 2). lack of rich inner structures for scalable modeling, and 3). limited understanding of the real world.

To address these three issues, I propose to strategically predict “latents” for the design of new generative models, where latents refer to the model’s intermediate representations during the generation process. First, I will demonstrate how integrating latents allows flexible architecture designs to enhance both efficiency and adaptability ,such as in the first non-autoregressive model for sequence generation. Next, I will show how to use latents to incorporate useful data structures for improved model scalability, especially in high-resolution images and videos. Moreover, I will demonstrate how to use latents to infuse world knowledge such as 3D for tasks like consistent view synthesis. Throughout the talk, I will cover various modalities, including text, images, and 3D. Finally, I will conclude with a discussion about the prevailing challenges and envision future paths that could lead to more flexible, scalable ,a nd knowledgeable next-generation generative models.
