Graph Learning for Fashion Compatibility Modeling

By: Weili Guan,Xuemeng Song,Xiaojun Chang,Liqiang Nie

This book sheds light on state-of-the-art theories for more challenging outfit compatibility modeling scenarios. In particular, this book presents several cutting-edge graph learning techniques that can be used for outfit compatibility modeling. Due to its remarkable economic value, fashion compatibility modeling has gained increasing research attention in recent years. Although great efforts have been dedicated to this research area, previous studies mainly focused on fashion compatibility modeling for outfits that only involved two items and overlooked the fact that each outfit may be composed of a variable number of items. This book develops a series of graph-learning based outfit compatibility modeling schemes, all of which have been proven to be effective over several public real-world datasets. This systematic approach benefits readers by introducing the techniques for compatibility modeling of outfits that involve a variable number of composing items. To deal with the challenging task of outfit compatibility modeling, this book provides comprehensive solutions, including correlation-oriented graph learning, modality-oriented graph learning, unsupervised disentangled graph learning, partially supervised disentangled graph learning, and metapath-guided heterogeneous graph learning. Moreover, this book sheds light on research frontiers that can inspire future research directions for scientists and researchers.

Earthquake Phenomenology from the Field

The April 20, 2013, Lushan Earthquake

By: Zhongliang Wu,Changsheng Jiang,Xiaojun Li,Guangjun Li,Zhifeng Ding

Based on the field investigation and the summary of the published research results of the April 20, 2013, Lushan, Sichuan, China, MS7.0 earthquake, having occurred along the same fault zone which accommodated the May 12, 2008, Wenchuan MS8.0 earthquake, this Brief tries to describe and discuss the special earthquake phenomenology associated with both the local geology and the changing society. Since the occurrence of this earthquake, there have been the scientific debates on (1) the seismo-tectonics of this earthquake which has no primary seismic fault discovered on the surface of the ground; (2) the relation between this earthquake and the Wenchuan earthquake (i.e., whether it can be considered as one of the aftershocks); and (3) how well have been accomplished in the reduction of earthquake disasters, 5 years after the Wenchuan earthquake. This Brief also tries to introduce the studies and practice of Chinese seismological agencies for the reduction of earthquake disasters. Due to language and cultural barriers, such an introduction makes sense not only for English readers but also for Chinese readers. For example, people (abroad) are always asking why there are so many Chinese seismologists working on earthquake prediction. In fact the Chinese wording 'earthquake prediction' has a much wider coverage than that in English. And actually the Chinese approach to (time-dependent) seismic hazard has no systematic difference from outside world in its methodology.

Fuzzy Hierarchical Model for Risk Assessment

Principles, Concepts, and Practical Applications

By: Hing Kai Chan,Xiaojun Wang

Risk management is often complicated by situational uncertainties and the subjective preferences of decision makers. Fuzzy Hierarchical Model for Risk Assessment introduces a fuzzy-based hierarchical approach to solve risk management problems considering both qualitative and quantitative criteria to tackle imprecise information. This approach is illustrated through number of case studies using examples from the food, fashion and electronics sectors to cover a range of applications including supply chain management, green product design and green initiatives. These practical examples explore how this method can be adapted and fine tuned to fit other industries as well. Supported by an extensive literature review, Fuzzy Hierarchical Model for Risk Assessment comprehensively introduces a new method for project managers across all industries as well as researchers in risk management. this area.

Empowered or Left Behind

Use of Technology During COVID-19

By: DeeDee M. Bennett Gayle,Xiaojun (Jenny) Yuan

Focused on the United States, this book summarizes the secondary impacts of COVID-19 due to the increased use of technology. Establishing the global response of social distancing, mandates for non-essential business, and working from home, the book centers on the disparate guidance provided domestically at the state and local levels. Marginalized populations are highlighted to identify areas where technology facilitated access and reach or contributed to difficulties catapulted by digital literacy or digital access issues. To explain how people may have been empowered or left behind due to a new and unique reliance on technology, this book is structured based on the social determinants of health domains. Specifically, this book explains how technology was an umbrella domain that impacted every aspect of life during the pandemic including access, use, adoption, digital literacy, and digital equity, as well as privacy and security concerns. Given this book’s focus on the impacts to marginalized populations, there is a thread throughout the book related to the use of technology to perpetuate hate, discrimination, racism, and xenophobic behaviors that emerged as a twin pandemic during COVID-19. Part I explains the defining differences between primary and secondary impacts, as well as the unique guidelines adopted in each state. Part II of the book is focused on specific domains, where each chapter is dedicated to topics including economic stability through employment, education, healthcare, and the social/community context through access to services. Part III focuses on unique technological considerations related to COVID-19, such as mobile health-related apps and privacy or security issues that may have posed barriers to the adoption and use of technology. Finally, the book ends with a conclusion chapter, which explicitly explains the advantages and disadvantages of technology adoption during COVID-19. These exposed benefits and challenges will have implications for policies, disaster management practices, and interdisciplinary research.

Advances in Multi-Channel Resource Allocation

Throughput, Delay, and Complexity

By: Bo Ji,Xiaojun Lin,Ness Shroff

The last decade has seen an unprecedented growth in the demand for wireless services. These services are fueled by applications that often require not only high data rates, but also very low latency to function as desired. However, as wireless networks grow and support increasingly large numbers of users, these control algorithms must also incur only low complexity in order to be implemented in practice. Therefore, there is a pressing need to develop wireless control algorithms that can achieve both high throughput and low delay, but with low-complexity operations. While these three performance metrics, i.e., throughput, delay, and complexity, are widely acknowledged as being among the most important for modern wireless networks, existing approaches often have had to sacrifice a subset of them in order to optimize the others, leading to wireless resource allocation algorithms that either suffer poor performance or are difficult to implement. In contrast, the recent results presented in this book demonstrate that, by cleverly taking advantage of multiple physical or virtual channels, one can develop new low-complexity algorithms that attain both provably high throughput and provably low delay. The book covers both the intra-cell and network-wide settings. In each case, after the pitfalls of existing approaches are examined, new systematic methodologies are provided to develop algorithms that perform provably well in all three dimensions.

An Introduction to Virtual Sound Barriers

By: Xiaojun Qiu

A virtual sound barrier is an active noise control system that uses arrays of loudspeakers and microphones to create a useful size of quiet zone and can be used to reduce sound propagation, radiation, or transmission from noise sources or to reduce noise level around people in a noisy environment. This book introduces the history, principle, and design methods of virtual sound barriers first, and then describes recent progress in research on the systems. Two virtual sound barrier systems, i.e., planar virtual sound barrier system and three-dimensional virtual sound barrier system, are discussed including applications, limitations and future direction discussions.
