It shows how to use minimal least squares method to fit data. We will generate one-dimensional regression sample set. Tree linear regression models will be constructed, their parameters will be tuned according to the...

This demo shows how to use indices of sorted sets and how to recover the unsorted set from the sorted one. % A set of values is gven; each value has its index k...

Plot the 1st Principal Component of the 2D sample set. The script uses a standard 1PC procedure and do not canter the matrix as it recommnded. Contents Get the data Normalize the matrix Caclulate...

This demo shows how to deal with the different hypothesis on data generation. The data generation hypothesis here is an assumption about the link function. We have a synthetic model and three link functions....

Below there are several peculiar counters, used in various algorithms on regression modeling Contents Count the features Count 2^n combinations of elements in a set Count 2^n combinations with reinsertion for n=1,2,… Also see...

This demo shows how to compute show a separation hyperplane to classify objects. The hyperplane separates one class of objects from another. Contents Generate model data in 2D The simplest way to get data...

The Newton-Raphson algorithm is used to obtain the optimal parameters of the regression model Contents Create a demonstration data set Set the constant for iteration convergence Define the initial value of the parameters The...

Use one of the following data samples to show the forecast Contents 1) electricity consumption 2) triangle example 3) trapezoid example 4) sine example run the forecasting algorithm show the results file: demo_ssa_forecast 1)...

The target function for optimization in regression analysis usually requires additional parameters and must be placed apart from the main module. It is convenient to have several target functions and use them in turn....
