Maira-Verde.jpeg

Dr. Maira Gatti de Bayser former Research Staff Member, has co-founded the IBM Research Brazil, the Brazilian Lab of IBM T.J. Watson Jr. Research Center. She successfully technically led and coordinated top R&D projects in the Deep Learning/Machine area for more than 15 years. She pioneered on the establishment of the Conversational Systems area in Brazil before ChatGPT. That resulted in national and international publications, patents, and system demonstrations, for instance, at IJCAI’2019, and the premier league organization “HUMAINE (HUman Multi-Agent Immersive NEgotiation Competition) 2020” at IJCAI’2020, which happened in 2021 due to Covid. All the R&D Cloud-based Machine Learning solutions that she has led had international and national publications in top AI Conferences, like AAAI and IJCAI, patents, and business results. Maira is a member of ACM, AAAI, and ACS. Maira holds Ph.D. (2009) in Science - Informatics, and M.Sc. (2006) in Informatics from PUC-Rio, Pontifical Catholic University of Rio de Janeiro, Brazil. Her Ph.D. entitled Engineering of Self-Organizing Emergent Multi-Agent Systems: A Design Method and Architecture contains a novel method that was implemented using Monte-Carlo Simulation, a Planner and Reinforcement Learning. While her M.Sc. work entitled Dependability of Law-Governed Open Multi-Agent Systems had a novel method to replicate law-mediated agents. Maira has 70 published scientific papers and 30 US Patents in AI.

Tutorial: Programming Conversational Agents with Akka Actors
The 18th European Agent Systems Summer School 2016

In this tutorial I present how conversational agents can be implemented as Akka Actors using a mixed-initiative dialog strategy (Gatti de Bayser et. al, 2017), i.e., by combining both the system- and user-initiative in a question and answer scenario. Akka is a toolkit and runtime that implements the Actor Model on the JVM and was inspired by Erlang in many ways. Akka can be used to build highly concurrent, distributed, and resilient message-driven applications. A large ecosystem of more than 250 Github projects has grown on Akka, in programming languages like Scala, Java, Groovy, and JRuby. The tutorial covers topics from agent pro-activeness, natural language processing, fault-tolerance, and finally an exemplar integration with a mobile app to demonstrate the Cognitive Investment Advisor Application, including the system and code.
