Speech Title: Distributed  Two-tier Deep Reinforcements Learning Framework for Cell-Free Network

Abstract: Intelligent wireless networks have long been expected to have self-configuration and self-optimization capabilities to adapt to various environments and demands. In this talk, we present a novel distributed hierarchical deep reinforcement learning (DHDRL) framework with two-tier control networks in different timescales to optimize the long-term spectrum efficiency (SE) of the downlink cell-free multiple-input single-output (MISO) network, consisting of multiple distributed access points (AP) and user terminals (UT). To realize the proposed two-tier control strategy, we decompose the optimization problem into two subproblems, AP-UT association (AUA) as well as beamforming and power allocation (BPA), resulting in a Markov decision process (MDP) and Partially Observable MDP (POMDP). The proposed method consists of two neural networks. At the system level, a distributed high-level neural network is introduced to optimize wireless network structure on a large timescale. While at the link level, a distributed low-level neural network is proposed to mitigate inter-AP interference and improve the transmission performance on a small timescale. Numerical results show that our method is effective for high-dimensional problems, in terms of spectrum efficiency, signaling overhead as well as satisfaction probability, and generalize well to diverse multi-object problems.

Speech Title: The Challenges and Opportunities of Wireless Rechargeable Sensor Networks

Abstract: Recently, the breakthrough of wireless charging technology gave birth to the concept of Wireless Rechargeable Sensor Networks (WRSNs). To achieve high efficiency wireless charging, there are several challenges: how to full use of the energy emitted from the charger; how to trade off the number of dead sensors and the charging efficiency in multi-node charging paradigm; how to transfer energy to mobile devices with non-deterministic mobility. In this talk, we will introduce several charging schemes and discuss the opportunities for the future development of wireless charging.

Speech Title: Adaptive Compression of Deep Neural Networks

Abstract: Model compression is crucial for accelerating deep neural networks while maintaining high prediction accuracy. In this talk, I will present a lightweight compression method termed Adaptive SensiTivity-basEd pRuning (ASTER) which dynamically adjusts the filter pruning threshold concurrently with the training process. This is accomplished by computing the sensitivity of the loss to the threshold on the fly (without re-training), as carried with minimal overhead on the Batch Normalization (BN) layers. ASTER then proceeds to adapt the threshold so as to maintain a fine balance between pruning ratio and model accuracy. Extensive experiments on numerous neural networks and benchmark datasets illustrate a state-of-the art trade-off between FLOPs reduction and accuracy, along with formidable computational savings.

Speech Title: Optimizing Crop Yields and Reducing Costs in Precision Agriculture through Metaverse-based Simulation and IoT-enabled Data Analysis

Abstract: Precision agriculture is an emerging field that has the potential to improve crop yields and reduce costs. With the advent of the metaverse, there is growing interest in exploring how precision agriculture can be integrated into virtual environments. We need to have a novel approach for optimizing crop yields and reducing costs using IoT-enabled precision agriculture in the metaverse. The approach should be designed to be scalable, robust, flexible, energy-efficient, reusable, and maintainable. The effectiveness of the approach must be demonstrated through a simulation-based evaluation using real-world data. This will highlight the immense potential of IoT-enabled precision agriculture in the metaverse and provide insights for future research and development in this exciting area.
