Brain-Inspired Hyperdimensional System for Efficient and Robust Cognitive Learning
Modern computing systems are plagued with significant issues in efficiently performing learning tasks. In this talk, I will present a new brain-inspired computing system that supports various learning and cognitive tasks while offering significantly high computation efficiency and robustness than existing platforms. Our platform utilizes HyperDimensional (HD) computing, an alternative method of computation that implements principles of the brain functionality: (i) fast learning, (ii) robustness to noise/error, and (iii) intertwined memory and logic. These features make HD computing a promising solution for today’s embedded devices with limited resources as well as future computing systems in deep nanoscaled technology that have issues of high noise and variability. To leverage the memory-centric nature of HD computing, I exploit emerging technologies to enable processing in-memory which is capable of highly-parallel computation and data movement reduction. I will also show how this architecture can accelerate a wide range of big data applications such as deep learning.
