Web16 de mar. de 2024 · Differential calculus is an important tool in machine learning algorithms. Neural networks in particular, the gradient descent algorithm depends on the gradient, which is a quantity computed by differentiation. In this tutorial, we will see how the back-propagation technique is used in finding the gradients in neural networks. After … WebThis leads to the following loss function $$ L_{avgdice} = 1 - DSC $$ The DSC is a measure of the overlap of the prediction and ground truth, i.e. twice the intersection divided by the overlap for each of the 9 organs and the background. The Dice Loss will thus help prevent the model from biasing the large objects in the image.
