Cognitive word embedding evaluation

Word embedding evaluation is traditionally done with word analogy tasks. However, this does not necessarily reflect the word representations humans have in their brains. Thus, a cognitively more plausible approach to evaluate word embeddings is to use them to predict brain activity signals [1,2,3,4].

The goal of this thesis or semester project is to build a comparison system of how well state of the art word-level and sentence-level embeddings can predict brain activity data such as eye-tracking, fMRI and EEG signals [5].
