    Get PDF
    We present the mathematical detail pertaining to the theory of support vector classifiers, focusing our attention on hard-margin linear classifiers. We describe the rationale behind support vector classifiers, and provide extensive foundational detail. We construct the primal problem and, subsequently, derive the dual problem. We also show how the primal problem can be derived from the dual problem. The paper is the first in a series, and is intended to be educational in nature

    A presentation we made during our graduation at Open Life Science (OLS) programme. The OLS program is for people interested in applying open principles in their work and becoming Open Science ambassadors in their communities. The slide deck describes our initiative for establishing Open Science Community Nigeria (OSCN) in April 2022 as a scientist-driven nonprofit organisation working to embed open science principles and practices, promote openness, transparency and reproducibility in science among scientists, network of researchers and societal stakeholders in Nigeria.

    Exploring the impact of a story-based teacher training programme on language and early literacy in 4- and 5-year-olds. Little Stars in the classroom: Did teaching practices change?

    More information about the Little Stars training programme and materials can be found at: www.wordworks.org.zaThis is the third in a series of five research briefs that explore the impact of Little Stars, story-based teacher training programme on language and early literacy in 4- and 5-year-olds. This brief focuses on whether resource-based teacher training led to take-up of the programme as intended, and the extent to which teaching practices changed through implementing the programme. We used Kirkpatrick’s model1 and focused on Level 3 (behavioural changes) to explore how teachers were using the programme and how the training translated into actual classroom practice.The project was funded by a British Academy research grant (ECE 190079). The research briefs were funded by the Lancaster University FST Impact Fund

    A pre-Tranind Model for Driver Drowsiness Detection

    Get PDF
    Drowsiness is among the important factors that cause traffic accidents; therefore, a monitoring system is necessary to detect the state of a driver’s drowsiness. Driver monitoring systems usually detect three types of information: biometric information, vehicle behavior, and the driver’s graphic information. Drowsiness detection methods based on the three types of information are discussed. A prospect for arousal level detection and estimation technology for autonomous driving is also presented. The technology will not be used to detect and estimate wakefulness for accident prevention; rather, it can be used to ensure that the driver has enough sleep to arrive comfortably at the destination. In this paper, we propose a Resnet (50) pre-trained model for driver drowsiness detection that achieves robust results and reaches 98% accuracy

    The Art of Self-Leadership during times of unprecedented Global Change

    No full text
    Introduction: Self-leadership has become as important as leading others, and subsequently, it has added an interesting dimension to the study of leadership. Scholars and practitioners alike have studied self-mastery, especially those concerned with human behavior and leadership. There is evidence that the ability to lead oneself ought to take precedence over leading others. It is against that background that this study, therefore, examines the art of self-leadership during times of unprecedented global change, where uncertainty abounds. Leadership theories posit that several factors and circumstances influence great leaders. Accordingly, both the conceptual and theoretical frameworks argue that the most critical tool in the exercise of leadership is the leader. Interestingly, empirical evidence reveals that leaders have enormous power to shape and redirect the course of history, and that begins with their ability to lead themselves first, then others. Methods: The study has employed a qualitative and exploratory approach using non-intrusive case studies. The data has been analyzed through an intepretivist lens. In addition, the paper applied phenomenology to get a better understanding of Self-leadership as a construct. Pursuantly, the paper interpreted experiences and meaning of the phenomenon. Lastly, the study also employed thematic analysis. Findings and Conclusion: The study, therefore, seeks to contribute to the broader understanding of the concept of self-leadership and as a developing framework. In addition, we found that self-leadership could be an effective complimentary framework to the other well-developed leadership theories. Thus, its findings could provide relevant insights into the art of self-leadership and may inspire future research. The results could equip leaders and individuals to better use the power within to transform themselves and societies
