Concepts & Categories - Neural Networks - Knowledge Representation - Semantic Memory



Research:

I am a third year graduate student at the
Rutgers University Mind Brain Analysis research group. Under Prof. Stephen Jose Hanson's supervision, I investigate high-level cognitive processes such as language, categorization, and learning through the use of artificial neural networks and computational modeling of dynamic brain function. Trying to unveil the nature of knowledge representation, I am interested in the formation and representation of semantic memory, which is our storage of conceptual and categorical knowledge of the world. More specifically, my research is aimed at understanding the organization and structure of semantic representational space, while also investigating the neural process underlying the formation of conceptual knowledge. Additionally, a second line of my research investigates the learning dynamics and representational processes of artificial neural networks, with a specific focus on how they are changed by deeper architectures (i.e. deep learning).
