Here, we use flip points to accomplish these goals for deep learning models with continuous output scores (e. g., computed by softmax), used in social applications.

Through numerical results, we confirm that some of the speculations about the decision boundaries are accurate, some of the computational methods can be improved, and some of the simplifying assumptions may be unreliable, for models with nonlinear activation functions.

Here, we propose a practical method that employs matrix conditioning to automatically design the structure of layers of a feed-forward network, by first adjusting the proportion of neurons among the layers of a network and then scaling the size of network up or down.

We show that distance between an input and the closest flip point identifies the most influential points in the training data.
