ABSTRACTS

**Harnessing Event-Driven and Multi-Agent Architectures for Complex Workflows in Generative AI System (\~ 30 min + QA) by Mary Grygleski**
We live in a complicated world and we are beginning to see that today’s generative AI systems are simply not well equipped to handle the increased complexity that is found especially in business workflows and transactions. Event-driven architectures and multi-agent systems offer a promising solution by enabling real-time processing, decentralized decision-making, and enhanced adaptability.
This presentation proposes an in-depth exploration of how event-driven architectures and multi-agent systems can be leveraged to design and implement complex workflows in generative AI. By combining the real-time responsiveness of event-driven systems with the collaborative intelligence of multi-agent architectures, we can create highly adaptive, efficient, and scalable AI systems. This presentation will delve into the theoretical foundations, practical applications, and benefits of integrating these approaches in the context of generative AI.

**Simpler Java Build Tools with Object Oriented Programming (45min) by Li Haoyi**
The Java language is known to be performant, easy to use, and with great IDE support, but Java build tools like Maven or Gradle do not always live up to that reputation. This talk will explore why build tooling is fundamentally such a difficult domain to work in, and how common concepts from object-oriented programming have the potential to simplify the build tool experience. We will end with a demonstration of an experimental new Java build tool "Mill" that makes use of these ideas, proving out the idea that Java build tooling has the potential to be much faster, safer, and easier than it is today.
