Claim 0:
1. A computer-implemented method for context aware anomaly detection, the method comprising:
receiving a signal including real-time data;
dividing the received signal into a set of training wavelets bounded by a respective training context;
generating 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;
in response to execution of a current context that is different from the training context, extracting current wavelets from a signal of the current context;
identifying 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
in response to determining that a total cumulative distance between the two sequences exceeds a predetermined threshold, identifying an anomaly.
