摘要:大数据是多源异构的。在信息技术飞速发展的今天,多模态数据已成为近来数据资源的主要形式。研究多模态学习方法,赋予计算机理解多源异构海量数据的能力具有重要价值。本文归纳了多模态的定义与多模态学习的基本任务,介绍了多模态学习的认知机理与发展过程。在此基础上,重点综述了多模态统计学习方法与深度学习方法。此外,本文系统归纳了近两年较为新颖的基于对抗学习的跨模态匹配与生成技术。本文总结了多模态学习的主要形式,并对未来可能的研究方向进行思考与展望。
Online distance learning is highly learner-centred, requiring different skills and competences from learners, as well as alternative approaches for instructional design, student support, and provision of resources. Learner autonomy and self-regulated learning (SRL) in online learning settings are considered key success factors that predict student performance. SRL comprises processes of planning, monitoring, action and reflection according to Zimmerman. And typically focuses on three key features of learners: (1) use of SRL strategies, (2) responsiveness to self-oriented feedback about learning effectiveness, and (3) motivational processes. SRL has been identified as having a direct correlation with students success, including improvements in grades and the development of relevant skills and strategies. Such skills and strategies are needed to become a successful lifelong learner. This chapter introduces a Mobile Multimodal Learning Analytics approach (MOLAM). I argue that the development of student Self-Regulated Learning would benefit from the adoption of this approach, and that its use would allow continuous measurement and provision of in-time support of student SRL in online learning contexts.
