We are exploring AI frameworks that mimic how the mammalian brain senses and understands the world. Our goal is to develop an AI system will learn much like an infant learns, by simply observing the world and learning through observation. Eventually, the model should learn the structure of the world and existing associations, and accurately make predictions. We are using neuromorphic software and hardware concepts such as sparse coding, top-down feedback, spiking neural networks, and neuronal dynamics to create a machine intelligence that has a better understanding of the world in which we live.
