ABOUT THE WORKSHOP
Real-world ubiquitous computing systems face the challenge of requiring a significant amount of data to obtain accurate information through pure data-driven approaches. The performance of these data-driven systems greatly depends on the quantity and `quality' of data. In ideal conditions, pure data-driven methods perform well due to the abundance of data. However, in real-world systems, collecting data can be costly or impossible due to practical limitations. Physical knowledge, on the other hand, can be used to alleviate these issues of data limitation. This physical knowledge can include domain knowledge from experts, heuristics from experiences, as well as analytic models of the physical phenomena.
This workshop aims to explore the intersection between (and the combination of) data and physical knowledge. The workshop will bring together domain experts that explore the physical understanding of the data, practitioners that develop systems and the researchers in traditional data-driven domains. The workshop welcomes papers addressing these issues in different applications/domains as well as algorithmic and systematic approaches to apply physical knowledge. Therefore, we further seek to develop a community that systematically analyzes the data quality regarding inference and evaluates the improvements from the physical knowledge. Preliminary and on-going work are welcomed.
CALL FOR PAPER
With the physical knowledge, we can infer the target information 1) more accurately compared to the pure data-driven model, or 2) with limited (labeled) data, since it is often difficult to obtain a large amount of (labeled) data under various conditions. In recent years, researchers combine this physical knowledge with traditional data-driven approaches to improve the computing performance with limited (labeled) data. We aim to bring researchers that explore this direction together and search for systematic solutions across various applications. Topics of interests include, but are not limited to, the follows:
- - Innovations in learning algorithms that combine physical knowledge or models for sensor perception and understanding
- - Experiences, challenges, analysis, and comparisons of sensor data in terms of its physical properties
- - Sensor data processing to improve learning accuracy
- - Machine learning and deep learning with physical knowledge on sensor data
- - Mobile and pervasive systems that utilize physical knowledge to enhance data acquisition
- - System services such as time and location estimation enhanced by additional physical knowledge
- - Heterogeneous collaborative sensing based on physical rules
The application areas include but not limited to:
- - Human-centric sensing applications
- - Environmental and structural monitoring
- - Smart cities and urban health
- - Health, wellness and medical
Successful submissions will explain why the topic is relevant to the data limitation caused problem that may be solved through the physical understanding of domain knowledge. In addition to citing relevant, published work, authors must cite and relate their submissions to relevant prior publications of their own. Ethical approval for experiments with human subjects should be demonstrated as part of the submission.
Please submit short papers using the SIGCHI Extended Abstract format with no more than 8 pages of content. Submissions may include as many pages as needed for references. The submissions should not be anonymous.
