Abstract:
1. A method comprising, by one or more processors associated with one or more computing devices: accessing, by one or more of the processors, a set of samples of sensor data recording a plurality of environmental measurements taken by one or more environmental sensors; representing, by the at least one computer processor, each data value of the set of samples of the sensor data as a minterm to yield a set of minterms, each minterm within the set of minterms comprising a logical expression of one or more variables allocated to the data value of the sample of the sensor data, wherein a minterm is a logical expression of n variables that employs only a complement operator and a conjunction operator; generating, by one or more of the processors, a first binary decision diagram from the set of samples by applying a logical OR operation to the minterms of the set of minterms to generate the first binary decision diagram by generating a characteristic function ƒ identifying, by one or more of the processors, one or more samples of the set of samples that are associated with a given environmental annotation according to the first binary decision diagram; and determining whether the environmental measurements associated with the set of samples are valid by:
