E emexes Expert Licensed User Longtime User Oct 23, 2019 #2 I like that it goes to higher orders of polynomials than just a plain old boring straight line One method of measuring internal losses of a rotating system is to spin it up, measure how the rate at which it slows down, multiply by the rotating inertia, and fit to a quadratic (because friction/resistance is usually proportional to the square of the speed).

Click to expand... This is a primitive example of machine learning. The input is made of the X values and the desired output is the Y values. We have some known samples: the mapping between the X coordinates and the Y coordinates of the clicked points. We want to find a formula that will allow us to find the Y values based on other X values. If you have two points and you know that there is a linear relation between X and Y then it is trivial to find such formula. This example uses a more sophisticated algorithm to try to match more complex relations. Jeffrey Cameron said: Or, more accurately, how can this be applied to apps? Click to expand... It is probably a bit too primitive and simplistic to actually be used for something real, however inspiration is also important...
