Speech Title: Wireless Networked Multi-Robot Systems in a Smart Factory
Abstract: Industry 4.0 based on artificial intelligence and information communication technology emerges as a primary contributor to the digital economy and Internet of Things. In order to execute flexible production in real-time, smart manufacturing must holistically integrate 6G wireless networking, AI computing, sensing, and automatic control technologies. This talk explores the challenges of this complex systems engineering scenario, by modeling the operation of a smart factory as a wireless networked multi-robot system of production robots and transportation robots. The real-time multi-robot task assignment for flexible production has been innovated in a computationally effective way. Furthermore, the special sequential decision-making of a multi-robot manufacturing system is examined toward a multi-robot system of high yield. Applying social learning extends the resilience of precision operation in a networked multi-robot system while taking network topology into consideration. Wireless networked multi-robot system integrating AI and wireless comtrol reveals the new landscape of smart factories and Industry 4.0.

Speech Title: Deep Learning Approaches for Multiuser Communication Systems
Abstract: In conventional multi-user multiple-input multiple-output (MU-MIMO) systems with frequency division duplexing (FDD), channel acquisition and precoder optimization processes have been designed separately although they are highly coupled. In this talk, I will present an end-to-end design of downlink MU-MIMO systems which include pilot sequences, limited feedback, and precoding. To address this problem, a novel deep learning (DL) framework is proposed which jointly optimizes the feedback information generation at users and the precoder design at a base station (BS). Each procedure in the MU-MIMO systems is replaced by intelligently designed multiple deep neural networks (DNN) units. At the BS, a neural network generates pilot sequences and helps the users obtain accurate channel state information.

At each user, the channel feedback operation is carried out in a distributed manner by an individual user DNN. Then, another BS DNN collects feedback information from the users and determines the MIMO precoding matrices. A joint training algorithm is proposed to optimize all DNN units in an end-to-end manner. Numerical results demonstrate the effectiveness of the proposed DL framework compared to classical optimization techniques and other conventional DNN schemes.

Speech Title: HAWatcher: Semantics-Aware Anomaly Detection for Appified Smart Homes
Abstract: As IoT devices are integrated via automation and coupled with the physical environment, anomalies in an appified smart home, whether due to attacks or device malfunctions, may lead to severe consequences. Prior works that utilize data mining techniques to detect anomalies suffer from high false alarm rates and missing many real anomalies. Our observation is that data mining-based approaches miss a large chunk of information about automation programs (also called smart apps) and devices. We propose Home Automation Watcher (HAWatcher), a semantics-aware anomaly detection system for appified smart homes. HAWatcher models a smart home’s normal behaviors based on both event logs and semantics. Given a home, HAWatcher generates hypothetical correlations according to semantic information, such as apps, device types, relations and installation locations, and verifies them with event logs. The mined correlations are refined using correlations extracted from the installed smart apps. The refined correlations are used by a Shadow Execution engine to simulate the smart home’s normal behaviors. During runtime, inconsistencies between devices’ real-world states and simulated states are reported as anomalies. We evaluate our prototype on the SmartThings platform in four real-world testbeds and test it against totally 62 different anomaly cases. The results show that HAWatcher achieves high accuracy, significantly outperforming prior approaches. This work has been accepted by one of the top four security conferences - USENIX Security 2021 (acceptance rate = 17%).
