Some parameters of magnetic thin films are difficult or time-consuming to measure. For this reason, research is underway on methods that use machine learning to estimate these parameters from images of maze-like magnetic domains. We have previously demonstrated that it is possible to estimate the variance σ of the magnetic anisotropy constant with high accuracy in heterogeneous systems where σ is present. In this study, we focus on homogeneous systems where σ is deliberately excluded, and we investigate and report on the estimation limits and regions where estimation is difficult due to the absence of image features.
