| | Summary: |
| | This paper represents the results of provided research about influence of weights on
the unknowns. The research was conducted in the cases of classical Least Square
estimation of unknows as well as the generalized matrix inversion. The research was
provided for the six cases of 1D networks starting from the simplest cases to the more
complicated. The research encompassed hundred random variations of weights values
per each researched case in the range of (-0,3 - +0,3) related to the starting weights
value. The results showed relatively small influences of weights in considered range
on the variations of the unknowns. The possible practical importance of this research
is that the influence of wrong determined weights could be modelled and estimated in
advance. |
