Transformacioni model (Thin Plate Spline, TPS) koristi se za 2D transformaciju koordinata u geodeziji, koristeći skup kontrolnih tačaka iz izvornog i ciljnog koordinatnog sistema za izračunavanje parametara transformacije. Ovi parametri uključuju afine koeficijente (a1_x, a2_x, a3_x za X-koordinatu i a1_y, a2_y, a3_y za Y-koordinatu) i težine (w_x za X-koordinatu i w_y za Y-koordinatu), dobijene metodom najmanjih kvadrata putem Gausove eliminacije. Model osigurava tačno uklapanje na kontrolne tačke uz omogućavanje nelinearnih deformacija.
Statistički pokazatelji izračunati za reziduale validacionog skupa uključuju srednju vrednost (prosečna vrednost reziduala), standardnu devijaciju (mera raspršenosti oko srednje vrednosti), minimum i maksimum (ekstremne vrednosti reziduala), koren srednje kvadratne greške (Root Mean Square Error, RMSE, mera prosečne veličine reziduala), medijanu (srednja vrednost u sortiranim rezidualima) i varijansu (kvadrat odstupanja od srednje vrednosti).
Kao rezultat, program generiše TPS parametre za transformaciju koordinata, transformisane tačke iz ulaznih fajlova i statističke pokazatelje za procenu tačnosti modela, koji se čuvaju u tekstualnom fajlu za dalju analizu.
Ovaj pristup se primenjuje u geodeziji za konverziju koordinatnih sistema, geografskim informacionim sistemima (Geographic Information Systems, GIS) za poravnanje prostornih podataka, daljinskoj detekciji za registraciju slika i kartografiji za korekciju distorzija mapa.

Combining of a backpropagation neural network to simulate coordinate system transformation (translation, rotation, scaling, and Euler angles) as the conventional linear models (Helmert transformations) are not efficient in handling complex distortions. Divides data automatically into test and training sets, trains model with early stopping in target error, with parameter adjustment to optimize performance, and breaks linear constraints through machine learning (with a neural network with backpropagation fitting the relationship between coordinates of two sets with different coordinate systems, highlighting adaptation to nonlinear distortions).

Mathematical Models

Neural Network
Made up of input, hidden, and output layers. Uses sigmoid activation function to provide nonlinearity, with backpropagation of errors utilized to update weights and regularization used to prevent overfitting. Trains to convert input coordinates to output differences so that nonlinear, complex relations can be modeled.
Data Normalization
Input data is normalized before training to the range -1 to 1 for increased stability. Denormalization is done after prediction to produce original values.
Influence Matrix
Used to calculate the measure of influence of all points with the model and impact on model parameters.
