Marina Dubova

I am a Cognitive Science PhD student at Indiana University and a graduate visitor at the Center for Formal Epistemology at Carnegie Mellon University. My current research is scattered around these topics:

  1. I study grounded language learning in humans and AI, focusing on the effects of various aspects of naturalistic data, tasks, and learning curricula 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 investigate whether & in what ways learning new concepts and their labels influences how we perceive the world and what we are able to do.

  3. 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 the words refer to).

  4. To (hopefully!) enable effective progress on topics 1-3 (and more), I investigate the foundations of scientific methodology. Here, I attempt to rigorously test the efficiency of different epistemic strategies that the agents can follow when they are trying to learn about the world.

I combine theoretical analyses, behavioral experiments, and computational simulations in my research.

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 :)
