Which code indicates to the computation of normal vector of the hyperplane? #5
The core idea of this paper is to calculate a normal vector of classification hyperplane by using N queries.
However, after reading the source code, I cannot find which code related to the computation of normal vector of the hyperplane.

Is the
def black_grad_batchcorresponds to the normal vector? This function returnsgrad_f(It is located in https://github.com/thisisalirah/GeoDA/blob/master/GeoDA.py#L180), isgrad_fthe normal vector??
