Gradient clustering
WebWe suggest that the quality of the identified failure types can be validated by measuring the intra- and inter-type generalisation after fine-tuning and introduce metrics to compare different subtyping methods. In addition, we propose a data-driven method for identifying failure types based on clustering in the gradient space.
