Calculus – The Derivative

by ComputingNotes
Suppose function $latex y = f(x)$, then the derivative of the function can be denoted as: $latex f'(x), \frac{dy}{dx}, y’ or \frac{d}{dx}(f(x))$ BUT what does that mean actually? Derivative of a function? https://math.libretexts.org/Bookshelves/Calculus/Calculus_(OpenStax)/03%3A_Derivatives/3.02%3A_The_Derivative_as_a_Function

What is Gradient? Loss Function? Model Parameters? Gradient Descent?

by ComputingNotes
Gradient Descent: Optimization algorithm; minimizes errors between predicted and actual results; updates parameters by moving against the gradient Loss Function: aim is to minimize this function, closer to zero; measures how bad the prediction is in comparison to the actual true value; various methods are used; one is Mean Squared Error (MSE) Gradient: Slope; direction ...
