OPINION
We reverse.
On its face, the instant claimed invention is directed to
an operation of an algorithm for producing an updated, or
revised version of, a neuron parameter vector which is useful
for training a neural network. The instant claimed subject
matter therefore has practical utility. Even if the
mathematical algorithm by which the final result is reached
may be considered an abstract idea, that abstract idea is
clearly employed in a useful way. The transformation of data
through a series of mathematical calculations to produce the
updated version of the neuron parameter vector for training a
neural network constitutes a practical application of the
abstract idea or mathematical algorithm because it produces a
