Classification: CPC G | IPC G

Claim 10:
11. A computer program product for context aware anomaly detection, the computer program product comprising:
one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising:
program instructions to receive a signal including real-time data;
program instructions to divide the received signal into a set of training wavelets bounded by a respective training context;
program instructions to generate a prediction model for the training context by processing the set of training wavelets through a recurrent neural network to identify patterns in a sequence of data of a respective training wavelet;
program instructions to, in response to execution of a current context that is different from the training context, extract current wavelets from a signal of the current context;
program instructions to identify a pairwise match between same dimensions of the current wavelets and a wavelet pattern of the prediction model by aligning sequences of the current wavelet and sequences of the wavelet pattern of the prediction model; and
program instructions to identify an anomaly in response to determining that a total cumulative distance between the two sequences exceeds a predetermined threshold.
