EMDL: 5th International Workshop on Embedded and Mobile Deep Learning
https://emdl21.github.io
#####################################################################

In recent years, breakthroughs from the field of deep learning have transformed how sensor data (e.g., images, audio, and even accelerometers and GPS) can be interpreted to extract the high-level information needed by bleeding-edge sensor-driven systems like smartphone apps and wearable devices. Today, the state-of-the-art in computational models that, for example, recognize a face, track user emotions, or monitor physical activities are increasingly based on deep learning principles and algorithms. Unfortunately, deep models typically exert severe demands on local device resources and this conventionally limits their adoption within mobile and embedded platforms. As a result, in far too many cases existing systems process sensor data with machine learning methods that have been superseded by deep learning years ago.

Because the robustness and quality of sensory perception and reasoning are so critical to mobile computing, it is critical for this community to begin the careful study of two core technical questions. First, how should deep learning principles and algorithms be applied to sensor inference problems that are central to this class of computing? This includes a combination of applications of learning some of which are familiar to other domains (such as the processing image and audio), in addition to those more uniquely tied to wearable and mobile systems (e.g., activity recognition). Second, what is required for current -- and future -- deep learning innovations to be either simplified or efficiently integrated into a variety of mobile resource-constrained systems? At heart, this MobiSys 2021 co-located workshop aims to consider these two broad themes. This year we place special focus on the emerging areas of i) resource allocation and scheduling for applying Federated Learning over embedded and mobile devices and ii) Edge-centric Learning that leverages the radical progress in Mobile Edge Computing (MEC) technologies. As such, we particularly encourage submissions on these two topics.

More specific topics of interest, include, but are not limited to:

• Resource-efficient Federated and Edge-centric Learning
• Compression of Deep Model Architectures
• Neural-based Approaches for Modeling User Activities and Behavior
• Quantized and Low-precision Neural Networks (including Binary Networks)
• Resource-efficient Federated Learning
• Mobile Vision/AR/VR supported by Convolutional and Deep Networks
• Audio Analysis and Understanding through Recurrent and Deep Architectures
• Optimizing Commodity Processors (GPUs, DSPs, NPUs, etc.) for Deep Models
• Hardware Accelerators for Deep Neural Networks
• Distributed Deep Model Training Approaches
• Applications of Deep Neural Networks with Real-time Requirements
• Deep Models of Speech and Dialog Interaction or Mobile Devices
• Partitioned Networks for Improved Cloud and Edge Offloading
• OS Support for Resource Management at Inference Time 


FULL PAPER SUBMISSIONS
Solicited submissions include both full technical workshop papers and white position papers. The maximum length of such submissions is 6 pages including references, and if accepted they will be published by ACM and appear in the ACM Digital Library.

• Submission Deadline: May 7th  - 11:59PM AOE (Final)

Mobile Serverless Workshop
https://www.it.uc3m.es/mbsvless21/
#####################################################################

Spurred by a growing need for programmability and flexibility, serverless computing is rapidly gaining the attention of mobile network stakeholders. The introduction of serverless architectures, also known as Function as a Service (FaaS), enables programmers to decompose network operations into atomic building blocks. This new paradigm represents the natural evolution of current cloud-native architectures, and a first glimpse into an actual fluid resource control that breaks current quantization and reaches ultimate flexibility. The advantages are evident and include: no service management, boosted resource multiplexing, liquid scalability, and high customization. The challenges to realizing a complete serverless approach in mobile networks are however important: software needs to be re-developed for this purpose, the scalability of routing traffic interconnecting functions must be explored, and resource orchestration becomes daunting. MobileServerless will facilitate discussions and novel contributions on the emerging topic of serverless networking for future mobile communications. MobileServerless welcomes both theoretical and more applied contributions, tools and methodologies, works-in-progress, demos and experience papers. Specific topics of interest include but are not limited to:

• Application of cloud-native and serverless concept to network function design
• Performance evaluation of cloud-native network deployment
• Simulation and theoretical evaluation of highly modular network functions
• New software architectures for network function design
• Management and orchestration solutions for cloud-native network functions
• Technical enablers for scalable packet forwarding in a cloud-native environment
• Security and privacy in serverless environments

Important Dates:
• Submission due: May 7th, 2021
• Notification of acceptance: June 4th, 2021
• Camera ready due: June 11th, 2021
• Workshop date: TBD (Mid July 2021)

1st Workshop on Zero Interaction Pairing and Authentication
http://zipa.cs.luc.edu/
#####################################################################

Zero-interaction pairing (ZIP), zero interaction authentication (ZIA) and continuous authentication are emerging techniques that enable users and devices to form self-organizing networks and mutually verify their identities without the use of passwords. Two devices that want to authenticate with one another both measure environmental noise signals and, using ZIP, can convert their measurements to authentication keys. In a scenario where both devices have already established a shared key, they can use ZIA to mutually verify their proximity to one another, for example as a second authentication factor. Network formation with ZIA and ZIP offers the advantage of being both secure and transparent to the user in the sense that no user involvement is required to configure a network. ZIA and ZIP have tremendous potential as an alternative to passwords, particularly in unattended systems like those in the Internet of Things. But ZIA and ZIP also represent a relatively new form of authentication, and we lack a comprehensive understanding of many of their practical and theoretical properties. This workshop aims to serve as a forum for researchers who are interested in ZIA to discuss unsolved problems and formulate new research directions with the goal of making ZIA a practical, secure, and user-friendly form of authentication. Submissions should be no more than 6 U.S. letter pages in PDF format, including all references, figures, and tables.

Topics of interest include:

• Information-theoretic fundamentals and limitations of ZIA
• New key reconciliation techniques
• New key generation techniques
• Applications of ZIA
• Real-world deployment experiences with ZIA systems
• Methods of sampling or extracting environmental noise signals
• Methods for distinguishing legitimate users from imposters on ZIA networks
• Techniques for compromising security of ZIA authentication systems
• Microcontroller-friendly techniques for evaluating key quality in real time

Important Dates:
• Paper Submission Deadline:  May 7th
• Notification of Acceptance: May 28th
• Camera Ready Deadline:      TBA

HealthDL: Deep Learning for Wellbeing Applications Leveraging Mobile Devices and Edge Computing
https://cis.temple.edu/~yanwang/healthdl2021/
#####################################################################

The availability of affordable wearable Internet of Things (wIoT) and edge devices with embedded sensors has revolutionized intelligent health and wellness applications. Users often use wIoT and smartphones to collect medical data and send them to the cloud for further analysis. Edge-based solutions, where analysis and inference of such data are carried out on edge devices, have been proposed to address users' security and privacy concerns since users' sensitive data is not transferred to untrusted cloud servers for inferencing. However, resource constraints on the edge devices also pose challenges in using deep learning solutions. Research needs to be conducted to produce efficient system designs, algorithms, and deep learning models that can be deployed in edge devices. Such outcomes will enable better personalization of health-related solutions and enhance users' experience. Furthermore, thanks to the ever-improving voice recognition and synthesis schemes, many wearables and smartphone applications now rely on voice assistants to interact with users. Existing work has shown that such interactions can significantly improve users' experience but incur significant security and privacy issues. This workshop aims to fill the gap between deep learning for intelligent healthcare and power-constrained wIoT and edge and create impactful solutions to help in the well beings of users.

This workshop invites researchers from academia and industry to submit their current research for fostering academic-industry collaboration. The scope of this workshop includes but not limited to the following topics:

• E2E deep learning for smart health applications.
• Deep learning for sensing, analysis and interpretation of wIoT healthcare data.
• Resource constrained deep learning schemes for smartphones and wIoT
• Edge-based Deep learning & AI models (e.g. sensor-based, visual-based or NLP-based) for mental health or other illnesses
• Transfer learning and model compression for smart health applications
• Context-aware ubiquitous healthcare systems based on wearables, edge machine learning
• Emerging applications or sensors for personalized health and fitness
