1. A method comprising:

  • by one or more computing devices, accessing a first binary decision diagram (BDD) representing a first sensor data from a first sensor and a second BDD representing a second sensor data from a second sensor; and

    determining whether the first sensor data and the second sensor data correlate by;

    constructing a third BDD by performing an OR operation between the first BDD and the second BDD;

    determining a first size of the first BDD, a second size of the second BDD, and a third size of the third BDD; and

    comparing the third size to a sum of the first size and the second size;

    wherein a degree that the first sensor data and the second sensor data correlate is indicated by an amount that the third size is less than the sum of the first size and the second size.
