1. A method for managing a network, the method comprising:
determining an occurrence of an operational issue on a network device of the network;
based on the determining, executing an encoding phase and a causal feature identification phase on a feature database, wherein the feature database is associated with the operational issue, wherein the encoding phase comprises creating a corresponding standardized entry for an entry in the feature database corresponding to the occurrence of the operational issue by encoding a standard value for each feature of the entry in the corresponding standardized entry based on a comparison of a raw value for that feature in the entry to a condition corresponding to that feature and the standard value for the feature is based on a result of the comparison of the raw value to the condition;
identifying a plurality of potential root causes using the encoding phase and the causal feature identification phase; and
performing an action based on the plurality of potential root causes.
