From Visualisation to Hypothesis Construction for Second Language Acquisition

Automating Second Language Acquisition Research: Integrating Information Visualisation and Machine Learning

Towards Linguistically-informed Representations for English as a Second or Foreign Language: Review, Construction and Application

The widespread use of English as a Second or Foreign Language (ESFL) has sparked a paradigm shift: ESFL is not seen merely as a deviation from standard English but as a distinct linguistic system in its own right. This s…

Towards a Data Analytics Pipeline for the Visualisation of Complexity Metrics in L2 writings

We present the design of a tool for the visualisation of linguistic complexity in second language (L2) learner writings. We show how metrics can be exploited to visualise complexity in L2 writings in relation to CEFR lev…

Super-resolution of THz time-domain images based on low-rank representation

Terahertz time-domain spectroscopy (THz-TDS) employs sub-picosecond pulses to probe dielectric properties of materials giving as a result a 3-dimensional hyperspectral data cube. The spatial resolution of THz images is p…

Visualisation and 'diagnostic classifiers' reveal how recurrent and recursive neural networks process hierarchical structure

We investigate how neural networks can learn and process languages with hierarchical, compositional semantics. To this end, we define the artificial task of processing nested arithmetic expressions, and study whether dif…
