An apparatus comprising: means for receiving , from one or more sensors associated with a physical environment, sensor data samples indicating a state of the physical environment or a change of the physical environment; means for receiving radio network information data samples associated with a radio network , including at least one radio network performance indicator; means for determining , based on a time relationship of one or more received sensor data samples with one or more of the received radio network information data samples such that both the one or more received sensor data samples and the one or more received radio network information data samples arrived or have a time stamp within a time window, a first set of one or more associated sensor and radio network information data samples; means for selecting a portion of the first set of one or more associated sensor and radio network information data samples that are relevant to performance of the radio network, including selecting one or more associated sensor and radio network information data samples that are associated with a change in radio network performance; means for labeling a reason for selection of the selected associated sensor and radio network information data samples that are relevant to performance of the radio network; means for developing a model that is trained based on at least the portion of the first set of one or more associated sensor and radio network information data samples that are relevant to performance of the radio network; and means for improving performance of the radio network based on at least the model. means for receiving , from one or more sensors associated with a physical environment, sensor data samples indicating a state of the physical environment or a change of the physical environment; means for receiving radio network information data samples associated with a radio network , including at least one radio network performance indicator; means for determining , based on a time relationship of one or more received sensor data samples with one or more of the received radio network information data samples such that both the one or more received sensor data samples and the one or more received radio network information data samples arrived or have a time stamp within a time window, a first set of one or more associated sensor and radio network information data samples; means for selecting a portion of the first set of one or more associated sensor and radio network information data samples that are relevant to performance of the radio network, including selecting one or more associated sensor and radio network information data samples that are associated with a change in radio network performance; means for labeling a reason for selection of the selected associated sensor and radio network information data samples that are relevant to performance of the radio network; means for developing a model that is trained based on at least the portion of the first set of one or more associated sensor and radio network information data samples that are relevant to performance of the radio network; and means for improving performance of the radio network based on at least the model. <EOS>
