Visual Question Answering (VQA) usually combines visual inputs like image and video with a natural language question concerning the input and generates a natural language answer as the output. This is by nature a multi-disciplinary research problem, involving computer vision (CV), natural language processing (NLP), knowledge representation and reasoning (KR), etc.Further, VQA is an ambitious undertaking, as it must overcome the challenges of general image understanding and the question-answering task, as well as the difficulties entailed by using large-scale databases with mixed-quality inputs. However, with the advent of deep learning (DL) and driven by the existence of advanced techniques in both CV and NLP and the availability of relevant large-scale datasets, we have recently seen enormous strides in VQA, with more systems and promising results emerging.This book provides a comprehensive overview of VQA, covering fundamental theories, models, datasets, and promising future directions. Given its scope, it can be used as a textbook on computer vision and natural language processing, especially for researchers and students in the area of visual question answering. It also highlights the key models used in VQA.

This book focuses on the current internal and external situation China is facing both from a macro perspective and a theoretical height, and puts forward practical development strategies and diplomatic ideas. It is of great methodological significance. At home, the development thought after the conclusion of the hundred-year change is the guiding thought for China's further development, and abroad, the international communication and the construction of international order highlighted by the hundred-year change also have important reference significance for the world's development.

The author of this book has a background in law, economics, management, information technology and many years of practical experience in e-government and government informatization, understanding the global information technology development situation, participates in a number of practical research projects, and has published several related field papers. This book starts from the practical problems of technological change and government governance, analyzing and summarizing the practical experience of information technology in China. At the same time, based on the comprehensive use of literature, cases, models, questionnaires and other research methods, the concept and analysis paradigm ¿Govtech" was first proposed on the basis of the integration of technological innovation and governance innovation, and the strategic ideas and countermeasures for the development of governance technology were proposed. This book can guide the development of China's network security and informatization, promoting the government's comprehensive deepening reform, and improving the level of national governance. It has important academic value and practical significance.

General secretary Xi JinPing stated on the ¿Three Critical Battles¿ conference that, targeted Poverty Alleviation (PA) has made phased progress, we must fight successfully and substantially.PA informatization is significant contents and innovative form.We discuss the relation between informatization and precise PA: IT enriches ways of PA, improves precision of supply and demand matching, and is good for improving the efficiency of PA work.For existing problems in poor area: people¿s deficiency of consciousness, lack of professionals, poor quality of service,narrow coverage, lack of material investment and support from policy and law, and imperfect management, we find out accesses and verify by case study.By analyzing the card establishing of PingShan county, we summarize current merits and demerits.Finally, we conclude nine suggestions: attach importance to long-term pertinence, establish card and recognize precisely, take advantage of IT multidimensionally, strengthen infrastructure construction, increase the additional value of modes and industries, innovate methods, build information sharing mechanisms, coordinate efforts, strictly organize and manage.
