Abstract: While we had outdoor localization systems with global coverage such as GPS for decades, these satellite-based systems do not work well indoors and there is to date no indoor equivalent to GPS. That may change with the recent availability of low-cost and low-power Ultra Wide Band (UWB) radio transceivers produced by Dacawave (now Qorvo) or NxP and their ongoing ubiquitous deployment in the latest smartphone and tablet generations. While these UWB radios enable accurate distance measurements, also new algorithms and system architectures are needed for scalable, robust, secure, and low-cost indoor localization to pave the way towards an indoor GPS equivalent. This talk will give an overview of our recent research towards this goal, with focus on reducing the infrastructure overhead, enabling highly-scalable localization systems, dealing with line of sight obstructions, and securing localization systems.

Abstract: Non-intrusive load monitoring (NILM) is to estimate individual appliance's power consumption from aggregated smart meter data, which is useful for optimized energy management and provisioning of customized services. While deep learning (DL) has achieved state-of-the-art NILM performance, it is still constrained by the dependency on large amounts of data and intensive computations on training. In this talk, we present a pre-training approach to address the generalization of DL models for NILM. We develop a meta-learning based approach and an ensemble learning based approach, which pre-train a base model and then fine-tune it with few-short learning when applied to an unknown dataset. In the second part of this talk, we present a Middle Window Transformer model, termed Midformer, for NILM. Existing models are limited by high computational complexity, dependency on data, and poor transferability. In Midformer, we first exploit patch-wise embedding to shorten the input length, and then reduce the size of queries in the attention layer by only using global attention on a few selected input locations at the center of the window to capture the global context. The cyclically shifted window technique is used to preserve connection across patches. We also follow the pre-training and fine-tuning paradigm to relieve the dependency on data, reduce the computation in modeling training, and enhance transferability of the model to unknown tasks and domains. The models are validated with two real-world datasets and shown to achieve a superior transferability performance compared with traditional DL and transfer learning methods.

Abstract: The transformation of our current cities into smarter cities will bring challenges in diverse areas such as the transportation system, the electricity system, and wearable systems, just to name a few. In smart cities, Information and Communication Technologies (ICT) will play a vital role for providing services in the urban environment. These services include real time monitoring and reaction in time through wireless sensor and actuator networks. Smart Grids (SGs), Intelligent Transportation Systems (ITS), Internet of Things (IoT), Electric Vehicles (EVs), and Wireless Sensor Networks (WSNs), supported by the advances in Artificial Intelligence (AI) and Machine Learning (ML), will be the building blocks of futuristic smart cities. In this presentation we will address ML techniques with a focus on autonomous vehicles and in particular on Connected and Autonomous Electric Vehicles (CAEVs) in smart cities. Current capabilities as well as limitations and opportunities of key AI enabling technologies will be reviewed, along with a discussion on the impact of such advances on society and the environment. All these technologies will help to build a smart city. A use case on evaluating traffic signs detection using deep convolutional neural networks (CNNs) such as Faster R-CNN for autonomous driving, will be provided.
