摘要： For quantum computers to fulfil their potential, they need to detect and correct errors in encoded information to reach sufficiently low error rates for reliable operation. For the first time, a device has been created in which encoded error rates improve as the system size is increased.

摘要： Picking a career stream profoundly influences people's abilities in different ways. Nowadays, choosing the correct career stream in advanced education is troublesome, as the number of people wanting to be in specific specializations is growing. Therefore, it is essential to be able to select the appropriate career path. This article proposes a system that can suggest streams in advanced education schools. This system is influenced by agent-based stream proposal systems (ASPS). The proposed system aims to make picking out the correct stream to study at school simpler for an individual. Different streams are evaluated based on seven pre-characterized models. In our system, three unique sorts of tests, learning styles, and coaching were coordinated in a way that caused the system to recognize an individual's interests and limits to an area of study. A sample of 238 participants was recruited for our questionnaire on accessibility, user-friendliness, accuracy, and satisfaction with the system. The incorporation of learning styles and coaching proved helpful in the study. The reliability and validity were proven in addition to incorporating a thinking-aloud protocol and immediate evaluation in the pre-, during and post-tests. To a large extent, respondents were satisfied with the model, as was revealed in the Likert scale response frequencies and percentages. The proposed system can be applied to undergraduates choosing engineering, medicine, arts and science degrees

关键词： Grading  

摘要： As educators we have attempted to increase the enrollment and retention of diverse learners into our computer science programs. These efforts might have included summer programs, mentoring programs, or inviting girl scouts onto campus. One area we might not have considered may be the most significant: how we assess students. This article considers the impact of grading practices, guided by "Grading for Equity" by Joe Feldman [5]. Feldman recommends practices that are accurate, bias resistant, motivational, and that reduce failure rates. In addition to presenting Feldman's recommendations, I highlight my preliminary experiences integrating grading for equity practices into my teaching. © 2023 Association for Computing Machinery.

摘要： This paper addresses the issue of the gender gap in ICT, which hinders the digital transition of many countries. We present a methodology (along with two use cases) that leverages girls’ greater sensitivity towards social issues - such as sustainability and health - to mitigate some well-known stereotypes that make ICT disciplines, and software engineering particular, unattractive to girls. Our strategy is based on a "grid" approach which aims to strengthen both some important vertical skills (e.g., environmental sustainability and programming) and horizontal ones, such as public speaking, team-building and team-working, the ability to compete, and social networking. As remarked by virtually all studies concerned with the design of effective teaching strategies, one of the main points to consider is that teaching technical skills is not enough. The importance of soft skills in education is underestimated, and there is an urgency to make up for the lack of these skills. Furthermore, many studies have noted that the lack of soft skills affects girls more than boys. Copyright © 2023, The Authors. All rights reserved.

摘要： Dimension reduction is an indispensable part of modern data science, and many algorithms have been developed. Here, the authors develop a theoretically justified, simple to use and reliable spectral method to assess and combine multiple dimension reduction visualizations of a given dataset from diverse algorithms. Dimension reduction is an indispensable part of modern data science, and many algorithms have been developed. However, different algorithms have their own strengths and weaknesses, making it important to evaluate their relative performance, and to leverage and combine their individual strengths. This paper proposes a spectral method for assessing and combining multiple visualizations of a given dataset produced by diverse algorithms. The proposed method provides a quantitative measure - the visualization eigenscore - of the relative performance of the visualizations for preserving the structure around each data point. It also generates a consensus visualization, having improved quality over individual visualizations in capturing the underlying structure. Our approach is flexible and works as a wrapper around any visualizations. We analyze multiple real-world datasets to demonstrate the effectiveness of the method. We also provide theoretical justifications based on a general statistical framework, yielding several fundamental principles along with practical guidance.

摘要： The transport network between cities is key in understanding epidemic outbreaks, especially in a vast country like Brazil with 5569 cities spread out over 8.5 million square kilometers. In order to study the COVID-19 spread in Brazil, we built a transport network where each city is a node and the edges are connections by land and air. Our findings have shown that by adding air connections, the average path length substantially decreases (70%) while the clustering coefficient remains almost unchanged, very typical of small-world networks. The airways are shortcuts connecting previously distant cities and hubs, therefore shrinking the distances in the network. Also, the cities with airports are central nodes, which makes them dissemination hotspots and key targets for interventions.
