We live in a world where technological advances are continually creating more data. By the year 2020, about 1.7 megabytes of new information will be created every second for each human on the planet. With the emergence of the Internet of Things, devices will generate massive data streams demanding services that pose huge technical challenges due to limited device resources. Sending all the data to the cloud for processing is not scalable, cannot guarantee the real-time response, and is often not desirable due to privacy and security concerns. To achieve real-time performance with high energy efficiency, we need to rethink not only how we can accelerate machine learning algorithms in hardware, but also we need to redesign the algorithms themselves using strategies that more closely model the ultimate efficient learning machine: the human brain. In this talk, we present a brain-inspired Hyperdimensional (HD) computing as an alternative computing paradigm. HD computing performs cognitive tasks by representing the values as patterns of neuron's activity in a high dimensional space. This approach enables a robust and highly efficient implementation of the most commonly used learning algorithms in both software and hardware including classification, clustering, regression, and recommendation systems.
