How Gradient Descent Works. Simple Explanation

Video explain what is gradient descent and how gradient descent works with a simple example. Basic intuition and explanation are revealed in the video.The content is:

0:09 - What is Gradient Descent.
0:30 - Example
0:39 - Step no. 1. Start with a random point and find the gradient (derivative) of the given function.
1:28 - Step no. 2. Set learning rate to get know how big should be a step to move forward on gradient descent to the opposite direction.
1:47 - Step no. 3. Perform calculations on iterations.
1:58 - Initialize parameters.
2:20 - calculations on the 1st iteration.
3:20 - calculations on the 2nd iteration.
4:26 - till we reach global or local minimum.

I hope that this explanation on how gradient descent works is useful for beginners of deep learning or good reminder for machine learning / deep learning experts.
