Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Learn what is Linear Regression Cost Function in Machine Learning and how it is used. Linear Regression Cost function in Machine Learning is "error" representation between actual value and model ...

And when you remember that the graph of a quadratic function is a parabola, this makes a lot of sense. Every parabola has an axis of symmetry that splits the parabola into two mirror-image pieces.

Building upon a recent anemometer design by using a calculation that could be done with a low-cost MCU to solve the nonlinearity problem.

Unlike a linear, graph, a quadratic graph has an equation which includes an x squared term.

Therefore, a line-search algorithm is an iterative process that optimizes a nonlinear function of one parameter () within each iteration k of the optimization technique, which itself tries to optimize ...

But how do you come up with a function to fit data? The basic idea is to create a quadratic function and vary the parameters such that the deviation of the actual data from the function is minimized.

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in ...
