Application ID: 12767354

Base Claim:
1. A method comprising: retrieving data from an electricity smart grid; encoding said data into a data modeling technique; performing a data quality rules discovery process using a data set of said electricity smart grid and said data modeling technique encoded with said data to said data set to produce a plurality of data quality rules associated with said electricity smart grid, said data quality rules discovery process comprising: applying each of a set of candidate conditional functional dependencies to a data segment having a predetermined length of data points of said data set; and after said applying, if a candidate conditional functional dependency has a result signature that does not meet a predetermined expectation, refining that candidate conditional functional dependency by eliminating an attribute in that candidate conditional functional dependency that took on the most values throughout the data set.

Claim 7:
7. The method of claim 1 , wherein said predetermined expectation comprises an error estimate of how man different data points would fail a candidate conditional functional dependency.
