I am interested in the acquisition, representation, organization and retrieval of knowledge and its use in reasoning.

Dissertation Work


My dissertation research investigates generic ways for an intelligent agent to organize and retrieve its past experience in an accurate and scalable way.

I have developed a generic episodic memory module that can be attached to a variety of applications and used for different tasks. Encapsulating the complexity of such a memory into a separate subsystem should reduce the complexity the overall system while allowing research to focus on the generic aspects of memory organization and retrieval in isolation of a specific domain and task.

An intelligent system can thus can store, recall and reuse experience of virtually every reasoning action taken. This is a different kind of knowledge that captures the result and also the context in which a reasoning action was taken. Availability of such knowledge can improve both the correctness and performance of a reasoning system by focusing on actions that are more likely to produce desirable results, given the history of their past applications.

A full description of the design, implementation and evaluation of the memory module can be found in my dissertation, entitled "A Generic Memory Module for Events".

A shorter description of memory module can be found in an earlier paper, presented at FLAIRS 20.


The generic memory module was applied to different tasks such as:
