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.

Abstract
In particular embodiments, a method includes accessing a first binary decision diagram (BDD) representing a data stream from a first sensor and a second BDD representing a data stream from a second sensor, 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 and second BDDs, determining sizes of the first, second, and third BDDs, and comparing the third size to the sum of the first size and the second size; where the degree that the first sensor data and the second sensor data correlate is indicated by the amount that the third size is less than the sum of the first size and the second size.
