Argument Component Boundary Detection (ACBD) is an important sub-task in argumentation mining; it aims at identifying the word sequences that constitute argument components, and is usually considered as the first sub-task in the argumentation mining pipeline. Existing ACBD methods heavily depend on task-specific knowledge, and require considerable human efforts on feature-engineering. To tackle these...
Robust perception-action models should be learned from training data with diverse visual appearances and realistic behaviors, yet current approaches to deep visuomotor policy learning have been generally limited to in-situ models learned from a single vehicle or simulation environment. We advocate learning a generic vehicle motion model from large scale crowd-sourced video data, and develop an end-to-end...
An emerging hyper-world encompasses all human activities in a social-cyber-physical space. Its power derives from the Wisdom Web of Things (W2T) cycle, namely, "from things to data, information, knowledge, wisdom, services, humans, and then back to things."' The W2T cycle leads to a harmonious symbiosis among humans, computers, and things, which can be constructed by large-scale converging...
Governments, enterprises and research institutions have participated the research and development of cyber-physical systems (CPS). However, the development of cyber-physical systems will be restricted by security threats and vulnerabilities. We summarize security threats and to the cyber-physical systems to provide a theoretical reference for research on cyber-physical systems and to provide effective...
This paper introduces a content-based image retrieval (CBIR) system based on Hadoop and Lucene. Hadoop is a kind of open source software with powerful parallelization and scalability and gradually becomes a popular technique for processing and storage of big data in recent years. We design and implement the system to overcome performance bottlenecks brought by computing complexity and big amount of...
When confronted with their internal and environmental dynamics, various software systems increasingly require self-adaptation capabilities. The vision above requires the self-adaptation approach to tackle these challenges and some software systems have their own specific implementations. However, in this paper a general supporting framework is proposed for software systems to self-adapt with running...
Heterogeneous platforms, integrating SMPs, clusters, GPUs, FPGAs, etc. are becoming the most popular architectures of supercomputers. Achieving high performance on CPUs or GPUs requires careful consideration of their different architectures, which challenges the capability and skills of programmers. In order to overcome the portability problem, OpenCL, a free cross-platform programming standard, is...
In order to save network bandwidth and system resource and improve video browse efficiency in client, a web video service based flash video technique is proposed. Firstly, the flash video data model is analyzed and a web video service architecture based on flash video is presented. Secondly, a flash video data processing flowchart with different kinds of video resource is designed for the video release...
