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...

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...
First, the CLIP model of color image based on LIP model of gray image is developed, and then analyzed the existing problems of gradient algorithm with HSV color image characteristics and the separation by color hue, saturation and brightness information and proposes a color image edge detection ...

关于SAC的版本问题,Spinning Up指出"The SAC algorithm has changed a little bit over time. An older version of SAC also learns a value function V_{\phi} in addition to the Q-functions; this page will focus on the modern version that omits the extra value function." Learning Q Q网络的学习...
WhenLearningFrequencyis the default value of -1, the creation of the minibatches (described in point a) and the learning operations (described in point b) are executed after each episode is finished. For simplicity, the actor and critic updates in this algorithm show a gradient update using ...
