Resumo
A quite recent development in Machine Learning, Deep Learning is having a huge impact in
Data Analytics, virtually replacing Artificial Neural Network for classification, regression and
time series forecasting tasks. The motivation for the work herein presented derives from the
question: What impact if any is Deep Learning making in Learning Analytics and Educational
Data Mining? In order to answer this question a systematic review of the literature was carried
out. It managed to identify and document the very first applications of Deep Learning in these
areas and the quite fast increase of related publications in the second half of the current decade.
The review also documented the main tasks in Learning Analytics and Educational Data Mining
that can benefit from this new approach, namely multimodal learning analytics and, more
generally, any Learning Analytics or Educational Data Mining task that can be modeled as a
supervised learning task where raw, unprocessed data is available. In order to develop a
Learning Analytics application in this guise, an experiment in automated essay scoring was
developed. The architecture used for the experiment was the stacked bidirectional LSTM. An
innovative aspect of the experiment was to study the effect of different word embedding
techniques has on the learning of the task.
