This criterion computes the cross entropy loss between input and target. ... label_smoothing (float, optional) – A float in [0.0, 1.0].

Here are a few examples of custom loss functions that I came across in this Kaggle Notebook. It provides implementations of the following custom loss functions in PyTorch as well as TensorFlow. Loss Function Reference for Keras & PyTorch. I hope this will be helpful for anyone looking to see how to make your own custom loss functions. Dice Loss

May 12, 2020 · Pytorch loss functions requires long tensor. Since I am using a RTX card, I am trying to train with float16 precision, furthermore my dataset is natively float16. For training, my network requires a huge loss function, the code I use is the following: loss = self.loss_func(F.log_softmax(y, 1), yb.long()) loss1 = self.loss_func(F.log_softmax(y1, 1), ...

However, I decided to further train the produced model using a different loss function (switched from L1 loss to L2 loss) but got the the error below.

If my output array is not an array of integers, but an array of float numbers, what kind of loss function I can use?

19.05.2021 · Loss.backward () found long, expected float. I am trying to code a test case for multi task learning, using my own loss function. The idea is that the output layer is 3-dimensional, the first output is used for 1D regression, the last two are used for 2-class classification. So, my combined loss function is a weighted sum of L1 loss and CELoss.

L1Loss() outputs = torch.tensor([[0.9, 0.8, 0.7]], requires_grad=True) labels = torch.tensor([[1.0, 0.9, 0.8]], dtype=torch.float) loss = criterion(outputs, ...

12.07.2020 · Yes, pytorch’s cross_entropy_loss()is a special case of cross-entropy that requires integer categorical labels (“hard targets”) for its targets. (It also takes logits, rather than probabilities, for its predictions.) It does sound like you want a general cross-entropy loss that takes probabilities (“soft tagets”) for its targets.

Just one follow-up question: why does pytorch convert numpy's float64 to Double Tensors? If Float Tensors are the go-to type for the language, I ...

However neither the size nor the data type ( FloatTensor ) is suitable for cross-entropy loss in the pytorch library .

Pytorch loss functions requires long tensor. Since I am using a RTX card, I am trying to train with float16 precision, furthermore my ...

This requires the targets to be smooth (float/double). However, PyTorch's nll_loss (used by ... What exactly are you looking for in the loss function?

Binary Cross Entropy Loss — torch.nn.BCELoss(). The input and output have to be the same size and have the dtype float. y_pred = (batch_size, ...

Jul 12, 2020 · So , i have been trying to implement the distilled model concept by Hinton et. al. in the paper Hinton Dark Knowledge. Accordingly i trained a cumbersome model , and depending on the results on the cumbersome model, i have to train the smaller model to fit the data. Now the output from the big cumbersome model is of the shape ( batch_size , outputs ) which is same as the as the output size ...

Jan 28, 2017 · Hi all! Started today using PyTorch and it seems to me more natural than Tensorflow. However, I would need to write a customized loss function. While it would be nice to be able to write any loss function, my loss function is a bit specific.So, I am giving it (written on torch)
