1. A method for identifying operating conditions of a system comprising a telecommunications system, the method comprising:
applying input data, relating to operation of the telecommunications system, to a multi-class model to classify the input data into one of a plurality of predefined classes each corresponding to a faulty or non-faulty operating condition of the telecommunications system;
determining a confidence level of the classification by the multi-class model;
if the confidence level is below a threshold confidence level, applying the input data to a plurality of binary models, each binary model being configured for determining whether the input data is or is not in a respective one of the predefined classes; and
if the plurality of binary models determine that the input data is not in any of said respective predefined classes, taking said input data into consideration when updating the multi-class model.
