Patent ID: 8407163

Claim:
A monitoring method comprising: recording a time sequence of information pertaining to a monitored device, network, or system comprising observations of and actions taken respective to the monitored device, network, or system; maintaining a hidden Markov model (HMM) operating on the time sequence of information and comprising a hidden state of the monitored device, network, or system; classifying a current state of the monitored device, network, or system using a classification value comprising an emission of the HMM that depends on the hidden state and on a selected portion of the time sequence of information, wherein the classifying includes aggregating the selected portion of the time sequence of information as an information representation of fixed dimensionality, the classification value comprising the emission of the HMM depending on the information representation of fixed dimensionality; generating an action recommendation for the current state of the monitored device, network, or system based on the classification value; wherein at least the maintaining, the aggregating, and the classifying are performed by a digital processor.
