I was here for convergence and learning rate of gradient decent. Incredible, Your way of explaining is understandable and pace is making concepts easy to grasp. Most importantly the simple examples for the explanation is the highlight and loved it.

Good explanation. It is somewhat also important to note that curve should be differentiable.

The most confusing part of this video is how he managed to write everything backwards on the glass so flawlessly

@sanataeeb969 Жыл бұрын

can't they write on their normal side then flip the video?

Nope he isnt writing backward..you can observe he seems to be using left hand to write ,but in actual right hand was being used

whats the difference between entropy and cost function

@shivanshpachauri2855 Ай бұрын

Entropy measures the impurity of a function while cost function is to measure how far off a model's prediction are from the true values

Im always confused by these screens or boards, whatever. Like how do you write on them? Do you have to write backwards or do you write normally and it kinda mirrors it?

Nice I learned more from this 7 min video than 1 hour long boring lecture

Let me clarify the concept of learning rate and step size in gradient descent: Learning rate: The learning rate is a hyperparameter that we set before starting the optimization process. It's a fixed value that determines how large our steps will be in general. Step size: The actual size of each step is determined by both the learning rate and the gradient at that point. Specifically: step_size = learning_rate * magnitude_of_gradient So: The learning rate itself is not the size of the steps from point to point. The learning rate is a constant that helps determine how big those steps will be. The actual size of each step can vary, even with a constant learning rate, because it also depends on the gradient at each point. To visualize this: In steep areas of the loss function (large gradient), the steps will be larger. In flatter areas (small gradient), the steps will be smaller. The learning rate acts as a general "scaling factor" for all these steps.
