- Abstract: Convolutional neural networks have shown extraordinary abilities in many
applications, especially those related to the classification tasks. However,
for the regression problem, the abilities of convolutional structures have not
been fully understood, and further investigation is needed. In this paper, we
consider the mean squared error analysis for deep convolutional neural
networks. We show that, for additive ridge functions, convolutional neural
networks followed by one fully connected layer with ReLU activation functions
can reach optimal mini-max rates (up to a log factor). The convergence rates
are dimension independent. This work shows the statistical optimality of
convolutional neural networks and may shed light on why convolutional neural
networks are able to behave well for high dimensional input.

We find that the variance of network weights and spatial concentration of large weights are the main factors that impact neural persistence.
We propose an extension of the filtration underlying neural persistence to the whole neural network instead of single layers.
This yields our deep graph persistence measure, which implicitly incorporates persistent paths through the network and alleviates variance-related issues.
