I eshe vopros, pri vibore tipa (vida, structuri i td) NeiroSeti, chem obosnovivat` vibor kolichestva sloev i chisla neironov na kazhdom sloe?

Chto zhe kasaetsya vibora neposredstvenno vida/tipa, nigde v literature ne nashel bolee "dostoinogo" obyasneniya predpochteniya BPN dlya finansov chem "naibolle chasto ispol`suetsya, horosho sebya zarekommendovala i td...".
A est` li kakoe-nibud` nauchnoe (metodologicheskoe) obosnovanie?

Ya vot sam proboval sravnivat` resul`tati progmosov tsen RAO 4 metodikami: Linear Regression, ARMA, GARCH & ANN (srednie dannie po 3 networks: Cortex, Trajan & NeuroSolutions) - tak u menya po ANN oshibka (MAPE) raz v 10 bol`she chem po ARMA poluchilas`...
Navernoe set` nepravil`no "programmiroval" (v smysle: tip, kol-vo sloev, neironov, activation function i td), da?
