The exploding gradient problem is a problem that arises when using gradient-based learning methods and backpropagation to train artificial neural networks. An artificial neural network, also known as a neural network or a neural net, is a learning algorithm that employs a network of functions to ...

Another solution to the exploding gradient problem is to clip the gradient if it becomes too large or too small. We can update the training of the MLP to use gradient clipping by adding the “clipvalue” argument to the optimization algorithm configuration. For example, the code below clips ...

First, we have built up intuition and its fundamental ideas by considering a regular gradient descent algorithm. We’ve extensively used a hillside analogy where we are trying to find the bottom while being blindfolded. We have learned that SGD and regular GD differ by the amount of data point...
What happens to the trainer flags for gradient clip value or gradient clip algorithm? How does someone know if those flags are being used or not? @awaelchli asked why not implement this in on_after_backward ? Using self.trainer.accelerator as part of the default implementation in the Lightnin...

If you look closely you will notice that both shadows are a little different, especially the blur part. It’s not a surprise because I am pretty sure thefilterproperty’s algorithm works differently than the one forbox-shadow. That’s not a big deal since the result is, in the end, qu...
