CALL FOR PAPERS

IEEE Signal Processing Magazine Special Issue on

Non-Convex Optimization for Signal Processing and Machine Learning
 

 

Optimization is now widely reckoned as an indispensable tool in signal processing and machine learning. Although convex optimization remains a powerful, and is by far the most extensively used, paradigm for tackling signal processing and machine learning applications, we have witnessed a shift in interest to non-convex optimization techniques over the last few years. On one hand, many signal processing and machine learning applications-such as dictionary recovery, low-rank matrix recovery, phase retrieval, and source localization-give rise to well-structured non-convex formulations that exhibit properties akin to those of convex optimization problems and can be solved to optimality more efficiently than their convex reformulations or approximations.

On the other hand, for some contemporary signal processing and machine learning applications-such as deep learning and sparse regression-the use of convex optimization techniques may not be adequate or even desirable. Given the rapidly-growing yet scattered literature on the subject, there is a clear need for a special issue that introduces the essential elements of non-convex optimization to the broader signal processing and machine learning communities, provides insights into how structures of the non-convex formulations of various practical problems can be exploited in algorithm design, showcases some notable successes in this line of study, and identifies important research issues that are motivated by existing or emerging applications. This special issue aims to address the aforementioned needs by soliciting tutorial-style articles with pointers to available software whenever possible. 

Topics of interest include (but are not limited to):
  • optimization fundamentals, including algorithm design and analysis techniques for generic and structured problems (e.g., difference-of-convex optimization, mixed-integer optimization, non-convex non- Lipschitz optimization, non-convex non-smooth optimization), parallel and distributed non-convex methods, and software toolboxes
  • big data analytics
  • blind demixing and deconvolution
  • computer vision and image processing applications
  • deep learning
  • localization
  • massive MIMO
  • phase retrieval
  • statistical estimation
  • structured matrix/tensor decomposition, such as low-rank matrix recovery and non-negative matrix/tensor factorization, with applications
Submission Process:

To enhance readability and appeal for a broad audience, prospective authors are encouraged to use an intuitive approach in their presentation; e.g., by using simple instructive examples, considering special cases that show insights into the ideas, and using illustrations as far as practicable.

Prospective authors should submit their white papers through the ScholarOne ManuscriptsTM system. Further guidelines and information on paper submission can be found on the SPS website.

Important Dates:  

White paper due: August 1, 2019
Invitation notification: September 1, 2019
Manuscript due: November 1, 2019
First review to authors: January 1, 2020
