Machine Learning Safety

By: Xiaowei Huang,Gaojie Jin,Wenjie Ruan

Machine learning algorithms allow computers to learn without being explicitly programmed. Their application is now spreading to highly sophisticated tasks across multiple domains, such as medical diagnostics or fully autonomous vehicles. While this development holds great potential, it also raises new safety concerns, as machine learning has many specificities that make its behaviour prediction and assessment very different from that for explicitly programmed software systems. This book addresses the main safety concerns with regard to machine learning, including its susceptibility to environmental noise and adversarial attacks. Such vulnerabilities have become a major roadblock to the deployment of machine learning in safety-critical applications. The book presents up-to-date techniques for adversarial attacks, which are used to assess the vulnerabilities of machine learning models; formal verification, which is used to determine if a trained machine learning model is free of vulnerabilities; and adversarial training, which is used to enhance the training process and reduce vulnerabilities. The book aims to improve readers’ awareness of the potential safety issues regarding machine learning models. In addition, it includes up-to-date techniques for dealing with these issues, equipping readers with not only technical knowledge but also hands-on practical skills.

Introduction to Chinese Natural Language Processing

By: Kam-Fai Wong,Wenjie Li,Ruifeng Xu,Zheng-sheng Zhang

This book introduces Chinese language-processing issues and techniques to readers who already have a basic background in natural language processing (NLP). Since the major difference between Chinese and Western languages is at the word level, the book primarily focuses on Chinese morphological analysis and introduces the concept, structure, and interword semantics of Chinese words. The following topics are covered: a general introduction to Chinese NLP; Chinese characters, morphemes, and words and the characteristics of Chinese words that have to be considered in NLP applications; Chinese word segmentation; unknown word detection; word meaning and Chinese linguistic resources; interword semantics based on word collocation and NLP techniques for collocation extraction. Table of Contents: Introduction / Words in Chinese / Challenges in Chinese Morphological Processing / Chinese Word Segmentation / Unknown Word Identification / Word Meaning / Chinese Collocations / Automatic Chinese Collocation Extraction / Appendix / References / Author Biographies

Huodegan

A Novel Index Reflecting Both Individual Wellbeing and Social Development

By: Wenjie Duan,Yumei Li

The core of this book is the concept of huodegan (获得感), which refers to a sense of gain that includes perceived individual wellbeing and social development. Given that measuring sense of gain has become critical in the new era of socialism with Chinese characteristics and along with the social indicators movement in the last decade, building an index for evaluating sense of gain becomes critical. Apart from reviewing the existing index systems for social development and policy and the previous studies exploring the sense of gain, this book highlights the importance of combining Chinese socio-cultural features, established theories, and index systems.

Cohesive Subgraph Search Over Large Heterogeneous Information Networks

By: Yixiang Fang,Kai Wang,Xuemin Lin,Wenjie Zhang

This SpringerBrief provides the first systematic review of the existing works of cohesive subgraph search (CSS) over large heterogeneous information networks (HINs). It also covers the research breakthroughs of this area, including models, algorithms and comparison studies in recent years. This SpringerBrief offers a list of promising future research directions of performing CSS over large HINs. The authors first classify the existing works of CSS over HINs according to the classic cohesiveness metrics such as core, truss, clique, connectivity, density, etc., and then extensively review the specific models and their corresponding search solutions in each group. Note that since the bipartite network is a special case of HINs, all the models developed for general HINs can be directly applied to bipartite networks, but the models customized for bipartite networks may not be easily extended for other general HINs due to their restricted settings. The authors also analyze and compare these cohesive subgraph models (CSMs) and solutions systematically. Specifically, the authors compare different groups of CSMs and analyze both their similarities and differences, from multiple perspectives such as cohesiveness constraints, shared properties, and computational efficiency. Then, for the CSMs in each group, the authors further analyze and compare their model properties and high-level algorithm ideas. This SpringerBrief targets researchers, professors, engineers and graduate students, who are working in the areas of graph data management and graph mining. Undergraduate students who are majoring in computer science, databases, data and knowledge engineering, and data science will also want to read this SpringerBrief.

The Global Economic Recovery 10 Years After the 2008 Financial Crisis

By: Ms.Wenjie Chen,Mr.Mico Mrkaic,Mr.Malhar S Nabar

This paper takes stock of the global economic recovery a decade after the 2008 financial crisis. Output losses after the crisis appear to be persistent, irrespective of whether a country suffered a banking crisis in 2007–08. Sluggish investment was a key channel through which these losses registered, accompanied by long-lasting capital and total factor productivity shortfalls relative to precrisis trends. Policy choices preceding the crisis and in its immediate aftermath influenced postcrisis variation in output. Underscoring the importance of macroprudential policies and effective supervision, countries with greater financial vulnerabilities in the precrisis years suffered larger output losses after the crisis. Countries with stronger precrisis fiscal positions and those with more flexible exchange rate regimes experienced smaller losses. Unprecedented and exceptional policy actions taken after the crisis helped mitigate countries’ postcrisis output losses.

Corporate market power has risen in recent decades, and new estimates in this note suggest that the likely wave of small and medium-sized enterprise bankruptcies from the ongoing pandemic will further strengthen market concentration. Whether and how policymakers should address this issue is hotly debated. This note provides new evidence on the policy relevance of rising market power and highlights possible implications for the design of competition policy frameworks and macroeconomic policies.

Navigating the Evolving Landscape Between China and Africa’s Economic Engagements

By: Ms. Wenjie Chen,Michele Fornino,Henry Rawlings

China and Africa have forged a strong economic relationship since China’s accession to the WTO in 2001. This paper examines the evolution of these economic ties starting in the early 2000s, and the subsequent shift in the relationship triggered by the commodity price collapse in 2015 and by the COVID-19 pandemic. The potential effects on the African continent of a further slowdown in Chinese growth are analyzed, highlighting the varying effects on different countries in Africa, especially those heavily dependent on their economic relationship with China. The conclusion offers a discussion of ways how African countries and China could adapt to the changing relationship.

Trade Integration and Global Value Chains in Sub-Saharan Africa

In Pursuit of the Missing Link

By: Céline Allard,Mr.Jorge I Canales Kriljenko,Mr.Jesus R Gonzalez-Garcia,Emmanouil Kitsios,Mr.Juan P Trevino,Ms.Wenjie Chen

This analysis of the extent of trade integration of sub-Saharan African (SSA) countries in the global economy as well as within the region over the 1995–2013 period focuses on four key concepts: (1) trade openness, captured by import and export flows; (2) the centrality in the global and regional trade network, a measure that takes into account not only the size of trade but also the number of trade partners and the respective weight of these trade partners in global trade; (3) gravity model estimates that account for country- and region-specific determinants of bilateral trade flows; and (4) global value chain (GVC) integration. Using both existing data and a newly available dataset based on multiregion input and output tables, this analysis led to several findings: (1) trade openness has increased strongly; (2) integration in the global economy has made the region more vulnerable to external shocks; (3) levels of trade flows emanating from sub-Saharan Africa are still only half the magnitude of those experienced elsewhere in the world; (4) the region still has ways to go to better integrate in GVCs; and (5) it is more critical than ever to make progress in filling the infrastructure gap by lowering tariff and nontariff barriers, improving the business climate and access to credit, and continuing to enhance education outcomes.

A Rebalancing Act for China and Africa

The Effects of China’s Rebalancing on Sub-Saharan Africa’s Trade and Growth

By: Mr.Roger Nord,Ms.Wenjie Chen

How does China’s new growth model affect sub-Saharan Africa? To address this question, this paper first looks at the growing ties between China and Africa; attempts to estimate more precisely the impact on growth through the trade channel; and finally draws some policy implications regarding whether this means an end of the Africa Rising narrative or merely the beginning of a new chapter.
