System, method and computer-readable medium for providing pattern matching

A tangible computer-readable medium storing instructions for controlling a computing device to generate a lower dimensional vector that represents a higher dimensional vector, the instructions comprising:

• choosing a dimension associated with the lower dimensional vector;
• generating a subvector from the higher dimensional vector;
• generating a random vector;
• and
• calculating the lower dimensional vector based on the subvector and the random vector to identify trends in data represented by the higher dimensional vector based on the lower dimensional vector.

A system for generating a lower dimensional vector that represents a higher dimensional vector, the system comprising:

• a processor of an electronic computing device;
• a module configured to control the processor to choose a dimension associated with the lower dimensional vector;
• a module configured to control the processor to generate a subvector from the higher dimensional vector;
• a module configured to control the processor to generate a random vector;
• and
• a module configured to control the processor to calculate the lower dimensional vector based on the subvector and the random vector and identify trends in the data represented by the higher dimensional vector based on the lower dimensional vector.
