Personality Recognition from Mouse and Keyboard Dynamics under Label Scarcity

Description: Personality is stable, which means no matter how much data we collect from a person, he or she always has only one corresponding score for a personality trait that will be the ground-truth label in recognition. This may lead to the harsh requirement for the dataset to cover a wide range of personality scores, increasing the difficulty of data collection and personality research.

Representation learning has been shown to be an effective approach to capturing the semantic pattern of the input that can generalise to different scenarios, datasets and downstream tasks. It has been widely investigated in NLP and CV. For example, word2vec uses a vector to represent each word.

This project will predict personality from a user's mouse and keyboard dynamics in a small dataset, using the representations learnt from larger mouse and keyboard datasets (without personality labels) in an unsupervised way.
