Spatial Correlation
The degree of statistical correlation between different spatial positions in input data. Adjacent pixels in natural images are typically highly correlated, which affects the effectiveness of network architecture design.

Spatial correlation reduces the advantage of weight sharing: the asymptotic error of the convolutional student rises as the input spatial correlation c increases, whereas the asymptotic error of the locally connected student is independent of c and is overall lower at the same learning rate.
