An example method may include a processing system including at least one processor determining a final weight set comprising weight factors to apply to each of a plurality of performance indicators for a predictive model associated with a target performance indicator using a genetic algorithm. The method may further include the processing system gathering a first plurality of measurements of the plurality of performance indicators for at least a portion of a cellular network, applying the predictive model to the first plurality of measurements of the plurality of performance indicators to generate a prediction for the target performance indicator, and adjusting at least one aspect of the cellular network in response to the prediction.
