https://medium.com/@paklong/3-different-ways-to-perform-gradient-descent-in-tensorflow-2-0-and-ms-excel-ffc3791a160a

Way1: without optimizers, pure math computation

Using GradientTape() and assign()

Way2: with optimizers biut without minimize funciton

Using GradientTape(), optimizers() and apply_gradients()

Way3: using minimize funciton

Using optimizers() and minimize()
