The search for exotic particles is one of the most challenging topics for physicists. This work aims to resolve the Big Data problem in the exotic particle area using the Apache Spark environment with the MLlib library. For this purpose, we analyze and discuss the performance of the following methods: Logistic Regression (LR), Decision Tree (DT), Random Forest (RF), and Gradient Boosted Tree (GBT). The results are very encouraging and prove that these proposed methods run efficiently with an Accuracy exceeding (83%). While the Gradient Boosted Tree (GBT) reaches a high AUC score 85%, better than Decision Tree (DT) and Random Forest. In this manuscript, we attempt to solve a big data problem using the "HEPMASS" dataset. Our data includes 10.5 million examples collected from the UCI website for the experimental phase. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

With the development of natural language processing technology, machine reading comprehension has been widely used in various fields such as QA systems and Intelligence engineering. However, despite numerous models are proposed in the general domain, there is still a lack of appropriate dataset and models for specific domains like anti-terrorism or homeland security to address this problem. Therefore, a Chinese reading comprehension data set in the field of anti-terrorism (ATCMRC) is constructed, and a generative machine reading comprehension model (AT-MT5) is proposed. ATCMRC was constructed in a semi-automated manner, and a domain-specific vocabulary is created based on the dataset to assist the AT-MT5. The model uses a hybrid attention layer is and a controlled answer generation layer to enhance text perception. Finally, the ATCMRC dataset and the AT-MT5 model is evaluated against existing approaches. The experimental results show that ATCMRC covers key issues in the domain and presents challenging MRC tasks for existent models, while AT-MT5 achieves better results in the domain specific dataset than the existing methods. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

International Perspectives in the Learning Sciences: Cre8ing a Learning World - 8th International Conference for the Learning Sciences, ICLS 2008

Animated diagrams representing dynamic systems hold great potential for improving the way people learn. However, so far the literature failed to find clear benefits of animated diagrams. Consequently it is worthwhile to investigate conditions under which enhancement of learning occurs. In the present study interactivity of the display and spatial ability of learners were examined. Three modes of presentation were compared: static diagrams, animation with interactivity, and animation with focus, also combined with interactivity. The interactive animation condition with focus acquired more knowledge than the other two conditions while the interactive animation condition scored worst. High-spatial ability subjects performed better on the knowledge acquisition measures than low-ability subjects. The interactive animation condition with focus is particularly beneficial for low-spatial ability subjects. These results indicate that combining the conditions of interactivity and focus does lead to improvement in learning from animations, particularly for low-spatial ability subjects.

International Perspectives in the Learning Sciences: Cre8ing a Learning World - 8th International Conference for the Learning Sciences, ICLS 2008

Problems in hypertext learning seem to relate with high levels of cognitive load that learners suffer during hypertext reading. One important factor that can increases cognitive load is the number of links per page (DeStefano & LeFevre, 2007). Several navigation support techniques, such as link suggestions, have been proposed to reduce cognitive load. In an experiment we tested the effects of number of links and link suggestions on cognitive load and learning. Participants used different hypertext versions, 3-links or 8-links per page, and with link suggestions or not. Participants with navigational support selected a more coherent reading text order and learned better at situational level. More interestingly, the effects on cognitive load were mediated by the hypertext reading order. Participants that selected a low coherent reading order suffered more cognitive load independently of the number of links presented. Implications for research and the design of navigation support systems are discussed.

2nd International Conference on the Pragmatic Web: "Building Common Ground on the Web", ICPW '07

Our goal is to develop a new format for scientific research articles, which will facilitate their use in a computer-assisted environment. By explicitly marking up rhetorical and knowledge elements in the text, an attempt is made to optimally represent the argumentation contained within the article. To this end, a structure of discourse segments and their relations is proposed. Applying this structure to a set of research articles could enable the creation or population of a system to visualize and access scientific argumentation within a corpus of research articles.

Guidance in the interface and transfer of task performance 07

Guidance in the interface and transfer of task performance

引用

25th Anniversary Conference of the European Association for Cognitive Ergonomics, EACE

作者： Van Nimwegen, Christof Van Oostendorp, Herre Center for Content and Knowledge Engineering Utrecht University Padualaan 14 3584 Utrecht Netherlands

Motivation - Previous research has shown that a "guided" interface where relevant task information is shown on screen (externalization) can result in worse performance than an "unguided" interface where users have to think more for them selves (internalization). In this study we investigate transfer of task performance. We will investigate whether switching from an "unguided" to a "guided" interface results in better performance than if it were the other way around. We also investigate whether the unguided interface enhances performance on a (near) transfer task. Research approach - We conducted an experimental study in two phases: an initial phase, and a transfer phase. In the initial phase, 45 students divided in a "guided" and "non-guided" condition solved a series of problems with the respective interfaces. After, in the transfer phase, they were presented with the opposite interface. This could happen during the first transfer task, or during the second one. Findings - The unguided interface resulted in more effcient performance than the guided interface. We attribute this to the fact that the unguided interface provokes more active thinking and contemplation. Furthermore, switching from an unguided to a guided interface had no effect on efficiency, while the other way around, it had a negative effect on efficiency. Finally, performance on a first transfer task with an unguided version after having worked with a guided version caused worse performance than other combinations. Take away message - Deeper levels of thought instigated by the unguided interface, causes more solid knowledge and stronger, more flexible strategies. This is also reflected when doing a transfer task. This can be important in situations where learning itself is the aim, but one can also think of situations where making errors generates a high cost.
