SC1 Neuromorphic Computing – Sensors and Deep Learning Networks

Description

First session: We start with a history of neuromorphic engineering; the analogues between neuronal physics and transistor physics, and the building blocks of neuromorphic systems

Second session: We will cover the circuit basics for the Dynamic Vision retina sensor, simple neuron models, and the use of this sensor in different applications

Third session: We will cover the circuit basics for the Dynamic Auditory Sensor, the similarity of the circuits to the biophysics of hearing

Fourth session: We will cover the basics of deep networks, the modifications of the architectures to incorporate bio-inspired features, and the use of these networks with the sensors

Objectives

Conceptual: To provide an understanding of how biological organizing principles are incorporated into electronics

Methodological: To show how transistor circuits are used to form bio-inspired models and how spiking sensors are used to solve practical applications.

Vita

Shih-Chii Liu (http://sensors.ini.uzh.ch) is at the Institute of Neuroinformatics, University of Zurich and ETH Zurich. Starting out as a trained electrical engineer from MIT, she worked at various companies in Silicon Valley before returning for her doctoral studies at California Institute of Technology. Currently, she is co-leading the Sensors group that develops low-power neuromorphic silicon auditory and vision sensory systems; VLSI event-driven bio-inspired processing circuits, event-driven sensory processing algorithms, and deep neural networks. Applications of the research include speech applications such as voice activity detection and object tracking.
