Complete Step-by-Step Gradient Descent Algorithm from Scratch

If you've been studying machine learning long enough, you've probably heard terms such as SGD or Adam. They are two of many optimization algorithms. Optimization algorithms are the heart of machine learning which are responsible for the intricate work of machine learning models to learn from data. It turns out that optimization has been around for a long time, even outside of the machine learning realm. Investors seek to create portfolios that avoid excessive risk while achieving a high rate of return.
