Language classrooms are occasionally anxiety-breeding situations. Foreign language classroom anxiety which negatively affects foreign language learning is typically associated with productive activities mainly speaking skill. To cope with the issue and overcome language learning difficulties, the present study was conducted to explore the impact of mobile-assisted language learning on enhancing...

Standard techniques (eg. Yule-Walker) are available for learning Auto-Regressive process models of simple, directly observable, dynamical processes. When sensor noise means that dynamics are observed only approximately, learning can still been achieved via Expectation-Maximisation (EM) together with Kalman Filtering. However, this does not handle more complex dynamics, involving multiple classe...

We propose a cloud-based filter trained to block third parties from uploading privacy-sensitive images of others to online social media. The proposed filter uses Distributed One-Class Learning, which decomposes the cloud-based filter into multiple one-class classifiers. Each one-class classifier captures the properties of a class of privacysensitive images with an autoencoder. The multi-class f...

Machine-learning solutions to classification, clustering and matching problems critically depend on the adopted metric, which in the past was selected heuristically. In the last decade, it has been demonstrated that an appropriate metric can be learnt from data, resulting in superior performance as compared with traditional metrics. This has recently stimulated a considerable interest in the to...

ideas Of course, middle-class people also make use of language in this kind of way, but as well as using this 'restricted code' Bernstein has shown that middleclass speakers have a greater control over what he terms the 'elaborated code'?the kind of speech used for communication with strangers, for the communition of complicated information, for expressing abstract ideas, rather than just descr...
