Prediction of stock market is a challenging task that has attracted researchers in various fields including the computational intelligence and finance. Since stock market data sets are intrinsically large, nonlinear and time-varying, it is extremely difficult to design models for forecasting the future directions with an acceptable accuracy. In this paper, an integrative and intelligent machine learning...

Configuring personal computers (PCs) in a careful manner definitely represent difficult decision problems in which given the diversity of hardware components possible for each PC nowadays, and the limited compatibility between some hardware components, we are interested to obtain an (sub-)optimal configuration for each specific usage restricted to a budget limit and other possible criteria. In this...

This paper proposes a number of models for integrating stochastic constraint solvers into constraint logic programming systems in order to solve constraint satisfaction problems efficiently. Stochastic solvers can solve hard constraint satisfaction problems very efficiently, and constraint logic programming allows heuristics and problem breakdown to be encoded in the same language as the constraints...

With the fast economic development in China, learning Chinese becomes very popular and significant worldwide. To most foreigners and even local students, one of the major challenges in learning Chinese is to write Chinese characters in correct stroke sequences that are considered as crucial in the Chinese culture. However, due to the potentially complex structures of Chinese characters together with...

Currently, the worldwide open and distance education institutions are carrying out teaching reform measures continuously to ensure open education quality, while teaching reform courses examination data analysis results will be able to reflect open education teaching reform effectiveness objectively. So Wilcoxon Rank Sum Test based examination data analysis scheme is proposed in this paper to detect...

Both educational data mining (EDM) and learning analytics (LA) focus on applying analytics and data mining techniques to extract useful information from large data sets. EDM is generally more interested in automated methods for discovery within the educational data while LA is relatively keen on applying human-led methods to understand the involved learning processes. Among the various fields of challenging...

Open education quality guarantee is a core issue in field of distance education. Data mining techniques are used to design effective teaching reform courses examination data analysis method would be a good way for checking teaching reform effects and could provide objective basis for open education quality assurance. This paper proposes a teaching reform courses examination data analysis solution...

Many learning analytics techniques to capture the learner's real-time responses are computationally intensive for running on mobile devices. In this paper, we propose a personalized learning platform named the PETAL facilitated by an efficient learning analytics application to detect learners' level of attentiveness and the proximity of their eyes to mobile devices and then alert learners to be more...

Most existing e-learning systems strictly require the course instructors to explicitly input the pre-requisite requirements and/or some relationship measures between the involved concepts/modules such that an optimal learning path as a sequence of the involved concepts can be determined for a class or an individual after considering the student’s academic performance, educational background, learning...
chapter
Learning analytics is targeted to better understand and optimize the process of learning and its environments through the measurement, collection and analysis of learners' data and contexts. To advise people's learning in a specific subject, most intelligent e-learning systems would require course instructors to explicitly input some prior knowledge about the subject such as all the pre-requisite...

The recent advance in cloud computing and mobile devices empowers many innovative e-learning systems or games with increased interactivity and improved features. In this paper, we consider an innovative framework of cloud-based e-learning games that can be assessed through mobile devices to enhance students' learning anytime and anywhere. Being model-based, our proposal is adaptive and highly portable...

Cloud computing technologies have been widely adopted to improve the competitiveness and efficiency of core operations in many enterprises through additional computational resources and/or storage as provided on the underlying cloud platforms. Yet there are relatively few studies on how cloud computing may enhance students' understanding of a specific subject in e-learning systems. In a research project...

Recent advances in camera hardware, processing capabilities, storage capacities, and communication technologies suggest an evolution of traditional multi-camera systems into networks of highly capable computational and smart cameras. These networks can be seen as visual sensor nodes that combine sensing with onboard processing and storage, and that are able to communicate with other similar sensors...

The Microsoft Kinect camera is a revolutionary and useful depth camera giving new user experience of interactive gaming on the Xbox platform through gesture or motion detection. Besides the infrared-based depth camera, an array of built-in microphones for voice command is installed along the horizontal bar of the Kinect camera. As a result, there are increasing interests to apply the Kinect camera...

With its unprecedented economic growth, China has gradually developed its significant influence on the global stage in recent years. As a result, there are increasing interests to learn Chinese all over the world. Intrinsically, learning Chinese is challenging to most foreigners and Chinese students as well due to the complex structures of Chinese Characters, the writing of characters in correct stroke...

The larger screen size, mobility, sensing and multi-touch input features of Android or iOS based devices like the iPad or Android tablet PC offer many exciting opportunities for real-life edutainment applications. An example is the learning of Chinese, especially to write Chinese characters in correct stroke sequences, that is typically considered as a difficult task to most foreigners. In this work,...
chapter
Most online e-learning systems often demand the pre-requisite requirements between course modules and/or some relationship measures between involved concepts to be explicitly inputed by the course instructors so that an optimizer can be ultimately used to find an optimal learning sequence of involved concepts or modules for each individual learner after considering his/her past performance, learner's...

Mobile tablets have become very popular due to their portability and the wide diversity of the applications available. The touch screens and built-in accelerometers facilitate different forms of input instead of keyboards and mice. Nowadays, high-resolution cameras become a standard feature in a mobile device. Nevertheless, this camera is seldom considered to serve as a form of user inputs to the...
