Co-design of machine-learning algorithms for control and perception with emerging technologies for structure-preservation in sensor data

Talk Abstract:

It is now widely recognized that structure in data can be substantially exploited to enhance the performance of machine learning. Our recent research has noted that the real-world presents rich structure, which can be exploited in perception tasks through sensors that preserve such structure.  We have proposed Physically-Integrated (PI) sensing as a technology that structures data around the (inter)actions and states of physical objects, through embedded, distributed, and form-fitting sensing directly coupled with objects. Large-Area Electronics (LAE), which can achieve large and conformal form factors, has been explored as a technology for achieving this. This talk will describe recent work pushing LAE to the giga-Hertz regime, opening up its use for wireless sensing. This leads to immersive wireless systems that can be integrated in walls and surfaces, and having extremely large apertures. Such apertures enable synthesis of rich radiation patterns for spatial addressing of density distributed PI sensors. However, they also required high-dimensional control over the many radiating elements, yet with limited analytical models for control. This talk presents that devices-to-algorithmic co-design of such systems, including: (1) the design and demonstration of multi-giga-Hertz wireless systems based on LAE; (2) use of deep-learning models for antenna control; (3) the integration of antenna controllers in complete perception pipelines, leveraging vision sensing for both selective sensor acquisition and sensor fusion with the acquired data.
