Anyone seen work related to data imbalance in NLP?

WebNov 29, 2024 · A problem with dice is that it can have high variance. Getting a single pixel wrong in a tiny object can have the same effect as missing nearly a whole large object, thus the loss becomes highly dependent on the current batch. I don't know details about the generalized dice, but I assume it helps fighting this problem. WebAug 23, 2024 · 14. Adding smooth to the loss does not make it differentiable. What makes it differentiable is. Relaxing the threshold on the prediction: You do not cast y_pred to np.bool, but leave it as a continuous value between 0 and 1. You do not use set operations as np.logical_and, but rather use the element-wise product to approximate the non ... running macro in excel https://brainardtechnology.com

WebAnd I think the problem with your loss function is the weights are not normalized. I think a normalized weights should be what you want. And w = 1/(w**2+0.00001) maybe should be rewritten as something like w = w/(np.sum(w)+0.00001).
