The paper delves into the realm of machine learning applications in sports, particularly focusing on the creation of ensembles of classifiers. It introduces a groundbreaking steps approach, utilizing Dynamic Classifier Selection (DCS), to elevate the precision of predicting outcomes in European football leagues. The methodology involves a meticulous exploration of the integration, preparation, and selection of diverse datasets, presenting a stark contrast to traditional classifier techniques. Rigorous experiments were conducted to validate the efficacy of the proposed steps approach, revealing a significant improvement in prediction accuracy compared to conventional methods. The article not only establishes the effectiveness of the steps approach but also hints at promising avenues for future research. These include the exploration of various voting schemes, the automation of ensemble construction, and the investigation of adaptive voting schemes. The overarching goal is to refine and enhance the process of classifier selection in the analysis of sports data. The results of this research pave the way for an automatic approach to building ensembles of classifiers, addressing a notable gap in the existing literature where such methodologies are not explicitly outlined. The primary focus of the research was to develop an automatic approach for creating classifier ensembles, aiming to substantially enhance the accuracy of sports data predictions. The absence of an explicit automatic approach in the current literature presented an opportunity for this study to contribute a novel step approach. The obtained results not only showcase the efficacy of the proposed method in predicting match outcomes accurately but also highlight the versatility of the approach by its applicability to real data from various sectors. This multifaceted contribution positions the steps approach as a valuable asset in the realm of sports dataanalysis and prediction.

Learning Analytics (LA) dashboards have become a popular medium for communicating to teachers analytical insights obtained from student data. However, recent research indicates that LA dashboards can be complex to interpret, are often not grounded in educational theory, and frequently provide little or no guidance on how to interpret them. Despite these acknowledged problems, few suggestions have been made as to how we might improve the visual design of LA tools to support richer and alternative ways to communicate student data insights. In this paper, we explore three design alternatives to represent student multimodal data insights by combining datavisualisation, narratives and storytelling principles. Based on foundations in data storytelling, three visual-narrative interfaces were designed with teachers: i) visualdata slices, ii) a tabular visualisation, and iii) a written report. These were validated as a part of an authentic study where teachers explored activity logs and physiological data from co-located collaborative learning classes in the context of healthcare education. Results suggest that alternatives to LA dashboards can be considered as effective tools to support teachers' reflection, and that LA designers should identify the representation type that best fits teachers' needs.

Mobile eye tracking is an important tool in psychology and human-centred interaction design for understanding how people process visual scenes and user interfaces. However, analysing recordings from mobile eye trackers, which typically include an egocentric video of the scene and a gaze signal, is a time-consuming and largely manual process. To address this challenge, we propose a web-based annotation tool that leverages few-shot image classification and interactive machine learning (IML) to accelerate the annotation process. The tool allows users to efficiently map fixations to areas of interest (AOI) in a video-editing-style interface. It includes an IML component that generates suggestions and learns from user feedback using a few-shot image classification model initialised with a small number of images per AOI. Our goal is to improve the efficiency and accuracy of fixation-to-AOI mapping in mobile eye tracking.

Users often browse the web in an exploratory way, inspecting what they find interesting without a specific goal. However, the temporal dynamics of visual attention during such sessions, emerging when users gaze from one item to another, are not well understood. In this paper, we examine how people distribute visual attention among content items when browsing news. Distribution of visual attention is studied in a controlled experiment, wherein eye-tracking data and web logs are collected for 18 participants exploring newsfeeds in a single- and multi-column layout. Behavior is modeled using Weibull analysis of item (article) visit times, which describes these visits via quantities like durations and frequencies of switching focused item. Bayesian inference is used to quantify uncertainty. The results suggest that visual attention in browsing is fragmented, and affected by the number, properties and composition of the items visible on the viewport. We connect these findings to previous work explaining information-seeking behavior through cost-benefit judgments.
