Keynote title: "When less gets more; Using sparsity to resolve computationally intractable audio problems."

Abstract: Audio, like all other signal modalities, has seen its fair share of straightforward sparsity approaches. In this talk I will focus on some different ways that sparsity has been taken advantage of in audio processing problems. Using the context of source separation I will present some probabilistic formulations in which, surprisingly, in order to achieve sparsity one can simply maximize an l2-norm, and then I’ll extend this idea and show how we can scale these methods to very big data sets using sparse manifold methods. In both cases, the use of sparsity helps us reduce problems that are otherwise computationally intractable to relatively easier ones. I’ll then shift gears and describe how imposing sparsity in audio model parameters allows us once more to significantly reduce computational complexity. I will demonstrate that in the context of audio denoising neural network models, and I will show how sparsifying their parameters allows us to reduce the necessary processing to simple bit-wise computations which are well-suited for low-power hardware implementations while retaining the expressibility of a general neural network.

Bio: Paris Smaragdis is faculty at the Computer Science and Electrical & Computer Engineering departments at the University of Illinois at Urbana-Champaign. He is also a senior research scientist at Adobe Research. Prior to that he was a research scientist at MERL and he received his PhD from MIT. His work focuses on computational audition, and machine learning approaches to various audio signal processing problems. He is primarily interested in problems involving mixtures of sounds. He has been selected by the MIT Tech Review as one of the top 35 innovators under 35 years old in 2006, he is an IEEE Fellow, and an IEEE SPS Distinguished Lecturer.

Keynote title: "First-Photon Imaging and Other Imaging with Few Photons"

Abstract: LIDAR systems use single-photon detectors to enable long-range reflectivity and depth imaging. By exploiting an inhomogeneous Poisson process observation model and the typical structure of natural scenes, first-photon imaging demonstrates the possibility of accurate LIDAR with only 1 detected photon per pixel, where half of the detections are due to (uninformative) ambient light and dark counts. I will explain the simple ideas behind first-photon imaging, which include exploitation of transform-domain sparsity. Then I will present related subsequent work that avoids the potential loss of transverse resolution from transform-domain regularization and instead exploits only longitudinal sparsity. This later work yields methods robust to unknown, spatially varying ambient light and able to estimate multiple depths per pixel from about 10 detected photons per pixel.

The following informations are taken from the ICME 2016 website. Please refer to www.icme2016.org for latest updates.

All Workshop papers will have the following commonalities:

Length: Papers must be no longer than 6 pages, including all text, figures, and references.
Format: Workshop papers have the same format as regular papers. However, they need not be double blind.
Review: Reviews will be handled directly by the Workshop organizers.
Submission site: https://cmt.research.microsoft.com/ICMEW2016. Papers must be submitted under the track for the appropriate Workshop. Submissions may be accompanied by up to 30 MB of supplemental material following the same guidelines as regular and special session papers.
Presentation guarantee: As with accepted Regular and Special Session papers, accepted Workshop papers must be registered by the author deadline and presented at the conference; otherwise they will not be included in IEEE Xplore. A workshop paper may be covered by a workshop-only registration or by a full-conference registration.

Scope

Technology improvements in multimedia content generation have led to a continuous cycle of creation, processing, communication and consumption of information as part of our social interactions and entertainment. This has spurred the development of efficient ways to acquire, process, communicate and store vast amounts of data. One of the most prominent recent breakthroughs is the development of compressed sensing and sparse representations. To-date these techniques have had significant success in numerous areas of signal acquisition, parameter estimation, communication, and machine learning. These developments have found a home in a number of applications, including media retrieval, radar and medical imaging systems, and video compression, just to mention a few.

This workshop’s objective is to bring together leading researchers around the world to present their newest accomplishments, exchange latest experiences, and explore future directions in the important and evolving fields of CS and sparse representations. In particular, it is focused on the dissemination of recent results in multimedia methods and applications that take advantage of these techniques.

We are inviting original submission to this workshop in the form of full-length 6-pages papers, or short 2-pages position papers (these latter are not going to be published in the proceedings). Topics of interest include, but are not restricted to:

Theoretical aspects of compressive sensing and sparsity
Communication and networking applications
CS and sparsity for 5G communication systems
CS and sparsity for big data
CS and sparsity for media retrieval
CS and sparsity for speech, audio, image and video compression
CS and sparsity for detection, estimation and machine learning
Compressive imaging
Distributed applications of compressive sensing
Emerging applications of CS and sparsity
