  • Gaussian Limits in Two Inference Problems

    Mon, Nov 11, 2019, 4:30 pm to 5:30 pm

    Abstract: Distribution limits in large systems are often the key to understanding the fundamental limits or designing algorithms for inference and learning problems. Yet, sometimes, such distribution limit properties are not easily recognized, or only exist in some indirect forms. I would like to discuss two pieces of work with this flavor.

  • Towards Learning with Brain Efficiency

    Thu, Oct 17, 2019, 12:30 pm to 1:30 pm

    Abstract:  Modern computing systems are plagued with significant issues in efficiently performing learning tasks. In this talk, I will present a new brain-inspired computing architecture. It supports a wide range of learning tasks while offering higher system efficiency than the other existing platforms. I will first focus on HyperDimensional (HD) computing, an alternative method of computation which exploits key principles of brain functionality: (i) robustness to noise/error and (ii) intertwined memory and logic.

  • Implantable Electronics for Highly Parallel Neural Interfaces

    Tue, Oct 8, 2019, 4:30 pm to 5:30 pm

    Abstract: Implantable medical devices (IMD) are nowadays widely employed to restore functions to the impaired individuals suffering from diseases like deafness, blindness, cardiac insufficiency, incontinence, neural disorders, and many more. Such implantable systems become increasingly challenging, if a large number of sensing or stimulating sites needs to be realized - space and power budget, safety issues, high bidirectional data rates, as well as the vast number of electrical interfaces make the electronic circuit design a complex task of research and development.

  • Wireless Networks via the Cloud: An Information Theoretic View

    Fri, Sep 6, 2019, 4:30 pm to 5:30 pm

    Abstract: Cloud based wireless networks named also as Cloud Radio Access Networks

    (C-RANs) emerge as appealing architectures for next-generation wireless/cellular systems whereby the processing/encoding/decoding is migrated from the local base-stations/radio units (RUs) to a control/central units (CU) in the "cloud".

    The network operates via fronthaul digital links connecting the CU and the RUs (operating as relays).
