WebMay 18, 2024 · For each k, calculate the total within-cluster sum of squares (WSS). This elbow point can be used to determine K. Perform K-means clustering with all these different values of K. For each of the K values, we calculate average distances to the centroid across all data points. Plot these points and find the point where the average distance from ... 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.
