In the case of long-term multitasking, the whole society fell into the dark age of distraction. Admittedly, related research has proposed that students’ Attention Deficit has become a major warning to learn. Attention is the first step in learning. Students must take the initiative to pay attention to something, then they bechance upon learning in the learning process. Once attention has flaws, other more complex cognitive function will be affected. Therefore how to develop attention training to enhance the learning ability will be both the future focus of education and the major objective of this study. In this plan, the “adaptive digital training attention platform based on EEG features” will infer the situation of attention through detection of personal brainwave activity in the digital training process, and then to adjust training strategies real time when student is ongoing attention training adaptively, finally, we will examine whether students can successfully migrate the results of the training to the learning environment. The content of work in this plan includes: retrieving expert knowledge in the field of attention training, collecting training cases and digital design, classifying and inferring attention-EEG feature, constructing adaptive digital training attention platform based on EEG features and evaluating classroom attention and learning effectiveness

    Extended artificial chromosomes genetic algorithm for permutation flowshop scheduling problems

    No full text
    [[abstract]]In our previous researches, we proposed the artificial chromosomes with genetic algorithm (ACGA) which combines the concept of the Estimation of Distribution Algorithms (EDAs) with genetic algorithms (GAs). The probabilistic model used in the ACGA is the univariate probabilistic model. We showed that ACGA is effective in solving the scheduling problems. In this paper, a new probabilistic model is proposed to capture the variable linkages together with the univariate probabilistic model where most EDAs could use only one statistic information. This proposed algorithm is named extended artificial chromosomes with genetic algorithm (eACGA). We investigate the usefulness of the probabilistic models and to compare eACGA with several famous permutation-oriented EDAs on the benchmark instances of the permutation flowshop scheduling problems (PFSPs). eACGA yields better solution quality for makespan criterion when we use the average error ratio metric as their performance measures. In addition, eACGA is further integrated with well-known heuristic algorithms, such as NEH and variable neighborhood search (VNS) and it is denoted as eACGAhybrid to solve the considered problems. No matter the solution quality and the computation efficiency, the experimental results indicate that eACGAhybrid outperforms other known algorithms in literature. As a result, the proposed algorithms are very competitive in solving the PFSPs

    Artificial chromosomes with genetic algorithm 2 (ACGA2) for single machine scheduling problems with sequence-dependent setup times

    [[abstract]]Artificial chromosomes with genetic algorithm (ACGA) is one of the latest versions of the estimation of distribution algorithms (EDAs). This algorithm has already been applied successfully to solve different kinds of scheduling problems. However, due to the fact that its probabilistic model does not consider variable interactions, ACGA may not perform well in some scheduling problems, particularly if sequence-dependent setup times are considered. This is due to the fact that the previous job will influence the processing time of the next job. Simply capturing ordinal information from the parental distribution is not sufficient for a probabilistic model. As a result, this paper proposes a bi-variate probabilistic model to add into the ACGA. This new algorithm is called the ACGA2 and is used to solve single machine scheduling problems with sequence-dependent setup times in a common due-date environment. A theoretical analysis is given in this paper. Some heuristics and local search algorithm variable neighborhood search (VNS) are also employed in the ACGA2. The results indicate that the average error ratio of this ACGA2 is half the error ratio of the ACGA. In addition, when ACGA2 is applied in combination with other heuristic methods and VNS, the hybrid algorithm achieves optimal solution quality in comparison with other algorithms in the literature. Thus, the proposed algorithms are effective for solving the scheduling problems

    EA/G-GA for Single Machine Scheduling Problems with Earliness/Tardiness Costs

    No full text
    [[abstract]]An Estimation of Distribution Algorithm (EDA), which depends on explicitly sampling mechanisms based on probabilistic models with information extracted from the parental solutions to generate new solutions, has constituted one of the major research areas in the field of evolutionary computation. The fact that no genetic operators are used in EDAs is a major characteristic differentiating EDAs from other genetic algorithms (GAs). This advantage, however, could lead to premature convergence of EDAs as the probabilistic models are no longer generating diversified solutions. In our previous research [1], we have presented the evidences that EDAs suffer from the drawback of premature convergency, thus several important guidelines are provided for the design of effective EDAs. In this paper, we validated one guideline for incorporating other meta-heuristics into the EDAs. An algorithm named "EA/G-GA" is proposed by selecting a well-known EDA, EA/G, to work with GAs. The proposed algorithm was tested on the NP-Hard single machine scheduling problems with the total weighted earliness/tardiness cost in a just-in-time environment. The experimental results indicated that the EA/G-GA outperforms the compared algorithms statistically significantly across different stopping criteria and demonstrated the robustness of the proposed algorithm. Consequently, this paper is of interest and importance in the field of EDAs

    Addressing the advantages of using ensemble probabilistic models in Estimation of Distribution Algorithms for scheduling problems

    [[abstract]]Estimation of Distribution Algorithms (EDAs) have recently been recognized as a prominent alternative to traditional evolutionary algorithms due to their increasing popularity. The core of EDAs is a probabilistic model which directly impacts performance of the algorithm. Previous EDAs have used a univariate, bi-variate, or multi-variable probabilistic model each time. However, application of only one probabilistic model may not represent the parental distribution well. This paper advocates the importance of using ensemble probabilistic models in EDAs. We combine the univariate probabilistic model with the bi-variate probabilistic model which learns different population characteristics. To explain how to employ the two probabilistic models, we proposed the Ensemble Self-Guided Genetic Algorithm (eSGGA). The extensive computation results on two NP-hard scheduling problems indicate the advantages of adopting two probabilistic models. Most important of all, eSGGA can avoid the computation effort overhead when compared with other EDAs employing two models. As a result, this paper might point out a next generation approach for EDAs

    Multiple parents crossover operators: A new approach removes the overlapping solutions for sequencing problems

    [[abstract]]Maintaining population diversity throughout generations of Genetic Algorithms (GAs) is key to avoid premature convergence. Redundant solutions is one cause for the decreasing population diversity. To prevent the negative effect of redundant solutions, we propose a framework that is based on the multi-parents crossover (MPX) operator embedded in GAs. Because MPX generates diversified chromosomes with good solution quality, when a pair of redundant solutions is found, we would generate a new offspring by using the MPX to replace the redundant chromosome. Three schemes of MPX will be examined and will be compared against some algorithms in literature when we solve the permutation flowshop scheduling problems, which is a strong NP-Hard sequencing problem. The results indicate that our approach significantly improves the solution quality. This study is useful for researchers who are trying to avoid premature convergence of evolutionary algorithms by solving the sequencing problems

This kind of technology development not only makes life long education, initially a simple idea, become an ideology. Even more, it has become a consoled movement. However, if we want to realize and fulfil the function of distance education, we have to formulate a systematic plan. So that, we can fully utilize the education environment structured by the information technology and carry out the long-term goal of long distance education. Thus, this study tries to develop a systematic mode to carry out the distance education planning. This study will begin by using the viewpoint of Need-Capability Assessment. We will ask students what they need in the field of distance education regarding the lecture environment, course content and interaction mode. Furthermore, we will combine those needs with information technology and formulate a moderate distance education environment. And finally, we will use the "Need-Capability Assessment Matrix" to analyze the needs and capabilities of campus organizations. We try to find out the position of our planning project in the matrix and submit a consoled suggestion for the organization's needs and capabilities in this subject. We hope this will offer a further reference for installing the distance education environment. The result of this study will help our domestic education organizations develop a systematic approach to formulate the distance education planning and essentially make the information technology a real tool in the field of distance education
