Marina Dubova

I am a Cognitive Science PhD student at Indiana University. My current research revolves around two major themes:

  1. I study grounded language learning in humans and AI, focusing on the effects of various aspects of naturalistic data, tasks, and training regimes on concept learning. I take inspiration from the idea that natural communication is grounded in one’s goals, perception, and action in the world. I examine 1) why grounding is essential for human language learning, 2) what concrete aspects of grounding should be incorporated into language-learning AI systems to improve their capabilities, and 3) how this can be done.

  2. I study the mechanisms underlying the development of communication systems (e.g. human languages!) in groups of agents. Here, I am interested in the following questions: 1) how do the properties of evolved communicative systems depend on the learning mechanisms, communicative goals, and the structure of social interactions between the agents, 2) what pressures lead a group to converge on a shared set of communicative conventions, 3) what pressures force a group to increase and diversify their set of communicative conventions (e.g. number of categories that words refer to).

I combine theoretical analyses, behavioral experiments, and computational simulations in my research. I also like to think about scientific progress in general, which motivates me to constantly improve how I conduct my studies (recently, I started a new line of research on computational epistemology!).

When I am not learning or studying learning, I like to play music, sing, travel, conduct clay & glazing studies, and improve my bird categorization skills.

I am always enthusiastic to discuss your/my research and ideas. Please, feel free to contact me :)
