The world is becoming evermore precise - well at least our desire to measure it, quantify it, model it with ever more precision, is increasing. But it’s time to step back and think about just what these models are intended to accomplish. Our work on ‘attention approximation’ is all about understanding where people are placing their attention - while realising that there is a level of precision, moving above which, renders the model we are trying to create, useless - unfit for purpose.
