LambdaG and grammar as a behavioural biometric

After two long years in pre-print, the paper is finally published! We introduce a new method for authorship verification, LambdaG, which is very simple and yet outperforms or performs as well as complex neural methods. The findings support the theory that a person’s grammar is effectively a behavioural biometric (like a signature or gait).
