What We Do

Developing an AI system that will observe and learn from the world around it

at Drexel’s College of Computing & Informatics explores AI frameworks that mimic how the mammalian brain senses and understands the world. The researchers’ goal is to develop an AI system that will learn much like an infant learns, by observing the world and advancing from those observations. The model should learn the structure of the world and existing associations and accurately make predictions. Research applications include generative AI, cryptography and distributed systems.
