Utilising ontology-based modelling for learning content management

Learning content management needs to support a variety of open, multi-format Web-based software applications. We propose multidimensional, model-based semantic annotation as a way to support the management of access to and change of learning content. We introduce an information architecture model as the central contribution that supports multi-layered learning content structures. We discuss interactive query access, but also change management for multi-layered learning content management. An ontology-enhanced traceability approach is the solution

To go deep or wide in learning?

To achieve acceptable performance for AI tasks, one can either use sophisticated feature extraction methods as the first layer in a two-layered supervised learning model, or learn the features directly using a deep (multi-layered) model. While the first approach is very problem-specific, the second approach has computational overheads in learning multiple layers and fine-tuning of the model. In this paper, we propose an approach called wide learning based on arc-cosine kernels, that learns a single layer of infinite width. We propose exact and inexact learning strategies for wide learning and show that wide learning with single layer outperforms single layer as well as deep architectures of finite width for some benchmark datasets.Comment: 9 pages, 1 figure, Accepted for publication in Seventeenth International Conference on Artificial Intelligence and Statistic

Interaction as enquiry: learning with layered dynamic media

The interactivity afforded to the learner by the computer based media is often fairly restricted. This may be by design choice but is often brought about by resource constraints. The new layered media forms give educational media developers an opportunity to provide richer forms of interactivity, and some of the issues related to changes in the way that interactive materials might be created are discussed. The distinction is made between the interface viewed simply as an information source and the interface regarded as an environment to be manipulated and explored
