WebFew-shot object detection (FSOD) aims to efficiently detect novel instances by model transferring using a few novel-class samples after the base-class samples are pre-trained. However, catastrophic forgetting occurs when FSOD transfers to the novel-classes, making the transferred model unable to accurately detect base and novel class instances … Web39. There are basically two things to be said. The first is that if you look at the density for the multivariate normal distribution (with mean 0 here) it is proportional to. exp ( − 1 2 x T P x) where P = Σ − 1 is the inverse of the covariance matrix, also called the precision. This matrix is positive definite and defines via. ( x, y) ↦ ...
