Classification: CPC G | IPC G

Claim 5:
6. A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to:
receive, at a normalization layer of a neural network used to classify a file, a set of values associated with the file;
calculate, at the normalization layer, a numerical mean of the set of values;
calculate, at the normalization layer, a numerical standard deviation of the set of values;
normalize, at the normalization layer, the set of values using the numerical mean and the numerical standard deviation to define a set of normalized values;
provide to an activation layer of the neural network the set of normalized values, and provide to the activation layer the numerical mean and the numerical standard deviation used during the normalization, the numerical mean and the numerical standard deviation each being provided as an additional input; and
calculate, at the activation layer and based on the set of normalized values, the numerical mean, and the numerical standard deviation, a set of results used to classify the file.
