Flow data prediction and abnormality detection

A system for detecting an abnormality in a flow system, the system comprising:

• a memory in which flow feature extraction instructions and neural network instructions are stored;
• and
• a processor coupled to the memory, the processor being configured to obtain input flow data for the flow system over a series of time intervals;
• wherein the processor is configured, via execution of the flow feature extraction instructions, to sequentially process the input flow data to generate, for each time interval in the series of time intervals, flow feature data, the flow feature data being representative of a plurality of flow parameters for the input flow data at the time interval in the series of time intervals;
• wherein the processor is configured, via execution of the neural network instructions, to apply the flow feature data to a recurrent neural network, the recurrent neural network being configured to provide an assessment, for each time interval in the series of time intervals, of whether the input flow data is indicative of the abnormality being present in a following time interval in the series of time intervals.
