MakeITeasy : guiding higher education actors to take ownership of the development and strengthening of their digital skills

The MakeITeasy platform is the backbone of the University of Geneva's "Digital Skills" institutional project. The objective of the system is to allow the actors, students, teachers, researchers, administrative and technical staff to develop and strengthen their digital skills. It is a matter of allowing individuals to evaluate themselves to self-regulate. The design of the platform is organized around a framework of digital skills, which is based on the DigComp framework of the European Commission and the Digital Capabilities Framework of JISC. The MakeITeasy platform is organized around four components: 1) a self-positioning test, allowing people to situate themselves in the reference framework; this test produces 2) an individual digital skills profile, which offers then to compare oneself to 3) target profiles to be reached; and finally, 4) a recommendation system which lists training courses to fill the gaps in one's skills. The platform is currently being developed for the students, doctoral students, and teacher populations. The self-positioning tool covers the generic competencies of the reference framework in its entirety while being as concise as possible so that it can be completed in full. The questions are based on occupational situations because the context to which they are attached makes it easier to assess the mastery of the skill by different categories of members of the university community. The tool presents the same generic competency at least three times in different scenarios and uses the responses to the three situations to decide the level of mastery. The test situations and questions as well as the entire platform were evaluated by various user tests.

The survey revealed that in order to develop their speaking abilities, the students have adopted a number of direct and indirect speaking strategies. These strategies addressed a variety of areas, such as memory, cognition, compensation, metacognition, affective, and social interaction. Direct strategies are those that are explicitly taught to students. These include things like rehearsal, using visual, and using a dictionary. Indirect strategies are those that are not explicitly taught, but that students learn through experience. These include things like using planning, finding a speaking partner, and using humor. The study suggested that a combination of direct and indirect strategies can be effective in improving speaking skills. Teachers should consider using a variety of strategies to help their students improve their speaking skills. Keywords: Direct strategies, indirect strategies, speaking skills
Improved BAT Algorithm Using Density-Based Clustering

BAT algorithm is a nature-inspired metaheuristic algorithm that depends on the principle of the echolocation behavior of bats. However, the algorithm suffers from being stuck in the local optima early due to its poor exploration. An improved BAT algorithm based on the density-based clustering technique is proposed to enhance the algorithm’s performance.&#x0D; In this paper, the initial population is improved by generating two populations, randomly and depending on the clusters’ center information, and by getting the fittest individuals from these two populations, the initial improved one is generated. The random walk function is improved using chaotic maps instead of the fixed-size movement, and so the local search is improved as well as the global search abilities by diversifying the solutions. Another improvement is to deal with stagnation by partitioning the search space into two parts depending on the generated clusters’ information to obtain the newly generated solution and comparing their quality with the previously generated solution and choosing the best.&#x0D; The performance of the proposed improved BAT algorithm is evaluated by comparing it with the original BAT algorithm over ten benchmark optimization test functions. Depending on the results, the improved BAT outperforms the original BAT by obtaining the optimal global solutions for most of the benchmark test functions.

Can we unlock more information from interferometric sensors? Feasibility and performance analysis

The surface is the most representative part of an artwork and it is also the part most exposed to alterations due to interaction with the surrounding environment. Non-destructive surface monitoring is of crucial importance in preserving and conserving cultural heritage and optical interferometric techniques allow to acquire the surface structure down to the submicrometric scale. In this work, we start from laser microprofilometry based on conoscopic holography sensors to unlock a new way of measuring the surface. In the last years, this technique has proven effective for surface diagnostic in heritage science providing high-quality surface dataset on diffusive, highly reflective, and polychrome artworks. However, an open problem in profilometry is the spatial referencing of surface topography at the micrometer scale, due to the lack of references in the height data with respect to the visually readable surface. We have recently developed a solution that exploits the raw intensity signal collected by the single-point sensor (i.e. the backscattered signal of the laser diode) and the interferometric height dataset, which are intrinsically registered. This method provides additional information about material texture, color variations or artist’s marks that enable spatial registration and data fusion tasks, otherwise difficult in traditional laser profilometry. In this paper we analyzed the feasibility and the performance of the whole process chain from the acquisition to the exploitation of the dual height-intensity datasets, focusing the attention on the raw intensity signal interpreted as a “raw reflectance signal”. We demonstrate the effectiveness of the proposed approach by presenting results on exemplary case studies.
FLEX: A Fast and Light-weight Learned Index for kNN Search in High-Dimensional Space

&lt;p&gt;The &lt;em&gt;k&lt;/em&gt;-Nearest-Neighbors (&lt;em&gt;k&lt;/em&gt;NN) search in the high-dimensional space is a fundamental problem in many applications. However, retrieving the nearest neighbors from a large-scale and high-dimensional dataset is computationally challenging, i.e, existing approaches either suffer from high construction cost or unsatisfactory search performance. In this paper, we propose a fast and light-weight learned index FLEX for &lt;em&gt;k&lt;/em&gt;NN search in high-dimensional space. First, we develop a multi-module DNN framework that needs much less training examples than employing classical DNN models directly to reach the same accuracy level. Second, we propose a linear-time data layout algorithm which aims to maximize the accuracy under a search cost constraint. A bound of the expected approximation ratio of the proposed algorithm is also proved. Experimental evaluation shows that our index significantly outperforms the state-of-the-art indexes in terms of both time efficiency and space efficiency while maintaining competitive or better accuracy performance.&lt;/p&gt;
