This is a quick testing tool for a new data modeling technique introduced by Mike Poluektov and Andrew Polar.
Users can upload their own data as semicolon separated numbers and see the accuracy of the model. The data
is parsed and processed by JavaScript code in this HTML file. The code can be seen by 'View Page Source' option
of the browser. It can be saved to file, retained and modified.
The used model is KolmogorovArnold representation for multivariate function $G$
$$ y = G(x_1, x_2, x_3, ... , x_n) = \sum_{i=0}^{2n} \Phi_i \left(\sum_{j=1}^{n} f_{i,j}(x_{j})\right), $$
where parameters $x_j$ are inputs, $y$ is a target of modeling and set of functions $f_{i,j}$ and $\Phi_i$ constitute the model.
This model is considered by authors as alternative to neural networks. Provided list of data sets with inputs and corresponding targets,
the suggested method builds all involved functions not in parametric form but by constructing of their actual shapes.
The model functions are continuous and piecewise linear, and the only parameter that user needs specify is number of points per function.
The theoretical concept is published:
