Industry Workshops

Date/Time: Wednesday, June 7 10:50am – 12:20pm

Room: Nafsika B


Title: How AI and Signal Processing Solve Real-World Applications with MATLAB



As research continues to develop cutting-edge AI models across a range of signal processing tasks, AI is used in an even wider and more diverse set of Industry applications. When using machine learning and deep learning in the real world away from the limelight, engineers aim to take advantage of state-of-the-art results while also having to work with much smaller datasets and striving to contain implementation costs. Along with an increasing use of machine learning and deep learning, they also adopt a growing variety of signal processing methods, for example to lower the complexity of AI models and to improve the quality of signal datasets.


In this workshop, you will learn about some of the latest MATLAB updates for Signal Processing, Machine Learning, and Deep Learning, including through practical code examples. The highlights will include:

  • Labeling, augmenting, and synthesizing signal datasets
  • Improving datasets and models through preprocessing and feature extraction
  • Creating and training new deep learning architectures in MATLAB
  • Using state-of-the-art AI models for transfer learning
  • Accelerating learning and feature extraction with local and cloud-based GPUs
  • Generating embedded software prototypes including signal processing and deep learning


Some familiarity with MATLAB will be desirable but not strictly required.

Title: Workshop on AI-empowered Semantic/Feature-based Communications towards Wireless Metaverse


The forthcoming Metaverse will be the byproduct of a convergence of multiple technologies ranging from extended reality (XR) to artificial intelligence (AI), that must come together to create a second life. In Metaverse applications represented video, AI shines brightly for its powerful feature extraction and generation capabilities, providing key traction of transforming communication links from a mere pipe medium to a semantic/feature-based system. Such AI-empowered semantic communications are viewed as a revolutionary paradigm that can potentially transform how we design and operate wireless communication systems, equipping them with a novel apparatus for decision-making mechanisms that can enable the seamless operation of metaverse applications or enhance the orchestration of network resources.


Indeed, the emergence of the Metaverse and its use-cases requires a paradigm shift from current AI-empowered wireless networks towards AI-native wireless networks that embed contextual information from a Metaverse environment into minimal yet expressive representations. Moreover, signal processing, transmission protocols, and network architecture, including physical (PHY) layer processing, medium access control (MAC), and air-interface in general should be redesigned carefully, or even cross-layer interacted to build a pathway to semantic communications. Under a specific QoE evaluation, how to combine semantic/feature information extracted from raw data with network and channel conditions may need to be investigated according to different applications. In particular, multimedia content (e.g., 2D/3D video, haptic, holographic) requiring ultra high throughput and low latency is expected to dominate the mobile data traffic in wireless Metaverse, which could be studied as a typical Real-Time Broadband Communication (RTBC) application.


This workshop aims to bring together the leading researchers in the field, both from academia and industry, to exchange their views on Semantic/Feature-based Communications towards Wireless Metaverse. The topics of interest include but not limited to: Cross-layer interaction/optimization, Quality of experience (QoE) evaluation, Network architectures and protocols for semantic/feature-based communications, Semantics-aware sampling and transmission policy, Joint semantic/feature and channel coding, End-to-end communications, Knowledge-driven semantic language and representation, Intelligent transceiver in wireless Metaverse.
