Title: Artificial Intelligence and Computational Science: There is Plenty of Room in the Middle
Abstract
Unprecedented hardware capabilities and algorithmic innovations have enabled the acquisition and analysis of massive datasets and simulations of complex systems that were inconceivable only a decade ago.
Computing is transforming our intellectual capacity to tackle complex problems and fueling the Artificial Intelligence (AI) revolution that is changing our world.
Computational Science and AI have been drivers and benefactors of these advances, each in different ways, and originally, with different targets.
I will juxtapose pattern recognition with Learning of Effective Dynamics, physics based flow control and controllers learned via multi-agent reinforcement learning, to argue and that the intellectual space between these two fields contains a wealth of opportunities for advancing human knowledge and scientific discovery.

Title: Neural Abstractive Summarization: Methods and Applications
Abstract
This talk reviews past and recent work of our team on the topic of neural abstractive summarization. We will first present our divide-and-conquer approach for dealing with long documents and its application to summarizing scientific articles [1]. We will then discuss Bayesian active summarization, our approach to combining active learning with state-of-the-art summarization models [2,3]. Next, we will share our methods towards controlling the output of summarization models given a particular context, such as a topic, along with our corresponding evaluation metric [4]. Finally, we will present applications in healthcare and finance [5,6].

Title: Generative Models for Digital Humans.
Abstract
The past four years have witnessed the development of very powerful generative models such as the series of GPT models for language generation and diffusion models for image and video generation driven by language and other signals. In this presentation, I will discuss recent developments in contemporary machine learning models for generating photorealistic digital humans, as well as driving them. I will also discuss potential applications and challenges of these applications.
