Dice loss not decreasing
WebThe model that was trained using only the w-dice Loss did not converge. As seen in Figure 1, the model reached a better optima after switching from a combination of w-cel and w-dice loss to pure w-dice loss. We also confirmed the performance gain was significant by testing our trained model on MICCAI Multi-Atlas Labeling challenge test set[6]. WebApr 19, 2024 · A decrease in binary cross-entropy loss does not imply an increase in accuracy. Consider label 1, predictions 0.2, 0.4 and 0.6 at timesteps 1, 2, 3 and classification threshold 0.5. timesteps 1 and 2 will produce a decrease in loss but no increase in accuracy. Ensure that your model has enough capacity by overfitting the …

WebSep 9, 2024 · Hi, I’m trying to train a simple model with cats and dogs data set. When I start training on CPU the loss decreased the way it should be, but when I switched to GPU mode LOSS is always zero, I moved model and tensors to GPU like the bellow code but still loss is zero. Any idea ? import os import os.path import csv import glob import numpy as np # … WebI had this issue - while training loss was decreasing, the validation loss was not decreasing. I checked and found while I was using LSTM: I simplified the model - instead of 20 layers, I opted for 8 layers. Instead of scaling within range (-1,1), I choose (0,1), this right there reduced my validation loss by the magnitude of one order
