1. A method for determining a health of a system comprising: identifying groups of vibration data for the system, wherein a group of vibration data in the groups of vibration data comprises data for vibrations of the system at different frequencies over time, and wherein the groups of vibration data comprise images of the vibrations of the system; storing the groups of vibration data for the system in a number of associative memories in a computer system, wherein the number of associative memories each comprise a type of memory having an organization in which data stored in a corresponding associative memory may be accessed based on both direct and indirect relationships among different data stored in the corresponding associative memory, wherein each of the number of associative memories comprise both the data and associations between the data, and wherein each of the number of associative memories also comprise a corresponding content-addressable structure that is configured to map a set of input patterns to a set of output patterns; and identifying the health of the system based on the groups of vibration data in the number of associative memories.
