Hi, I'm Nunu, a researcher in dialogue systems, affective computing, and natural language processing.
Hi, I'm Nunu, a researcher in dialogue systems, affective computing, and natural language processing.
My research centers around creating an intelligent Human-Computer Interaction that is adaptive and affect-sensitive.
I'm currently working as postdoctoral researcher with Milica Gašić at Dialog Systems and Machine Learning Group at Heinrich Heine University Düsseldorf, Germany. I'm particularly interested in optimizing dialogue policies for task-oriented systems using reinforcement learning methods without any predefined action space.
In the past I focused on empathetic dialogue and emotion elicitation in chat-based dialogue systems. During my master's and Ph.D. my supervisors were Satoshi Nakamura, Sakriani Sakti, and Koichiro Yoshino. I have also worked with Graham Neubig, Randy Gomez, Dessi Lestari, and Ayu Purwarianti.
