[talks] Fwd: Seminar-Dr. Shijia Pan, Thursday, September 27

[Margaret Martonosi]

Hello all-

Reminder about this talk tomorrow by Dr. Shijia Pan who is a post-doc at CMU. CS402 at 12:30pm with pizza beforehand.   

Please let me know if you’re interested in talking 1-1 with her — she still has a couple afternoon slots left in her schedule.

All the best,
Margaret

> “Indoor Human Information Acquisition from Physical Vibrations”
>  
> Abstract:
> The number of everyday smart devices (such as smart TV, Samsung SmartThings, Nest, Google
> Home) is projected to grow to the billions in the coming decade. The Cyber-Physical Systems or Internet
> of Things systems that consist of these devices are used to obtain human information for various smart
> building applications. Different sensing approaches have been explored, including vision-, sound-, RF-,
> mobile-, and load-based methods, to obtain various indoor human information. From the system
> perspective, general problems faced by these existing technologies are their sensing requirements (e.g.,
> line-of-sight, high deployment density, carrying a device) and intrusiveness (e.g., privacy concerns).
>  
> My research focuses on non-intrusive indoor human information acquisition through ambient
> structural vibration, which is referred to as ’structures as sensors’. People’s interaction with structures in
> the ambient environment (e.g., floor, table, door) induces those structures to vibrate. By capturing and
> analyzing the vibration response of structures, we can indirectly infer information about the people and
> their actions that cause it. However, challenges remain. Due to the complexity of the physical world (in
> this case, both structures and people), sensing data distributions can change significantly under different
> sensing conditions. Therefore, from the data perspective, accurate information learning through a pure
> data-driven approach requires a large amount of labeled data, which is costly and difficult if not
> impossible to obtain in real-world sensing applications. My research addresses these challenges by
> combining physical knowledge and data-driven approaches. Specifically, my system can robustly learn
> human information from limited labeled data distributions by iteratively expanding the labeled dataset.
> With insights into the relationship between changes of sensing data distributions and measurable physical
> attributes, the iterative algorithm guides the expansion order by measured physical attributes to ensure a
> high learning accuracy in each iteration.

> Bio:
> Dr. Shijia Pan is a postdoctoral researcher at Carnegie Mellon University. She received her Bachelor's
> degree in Computer Science and Technology from University of Science and Technology of China and
> her Ph.D. degree in Electrical and Computer Engineering at Carnegie Mellon University. Her research
> interests include cyber-physical systems, Internet-of-Things (IoT), and ubiquitous computing. She worked
> in multiple disciplines and focused on indoor human information acquisition through ambient sensing.
> She has published in both top-tier Computer Science ACM/IEEE conferences (IPSN, UbiComp) and
> high-impact Civil Engineering journals (Journal of Sound and Vibration, Frontiers Built Environment).
> She is the recipient of numerous awards and fellowships, including Rising Stars in EECS, Nick G.
> Vlahakis Graduate Fellowship, Google Anita Borg Scholarship, Best Poster Awards (SenSys, IPSN), Best
> Demo Award (Ubicomp), Best Presentation Award (SenSys Doctoral Colloquium), and Audience Choice
> Award (BuildSys) from ACM/IEEE conferences.
