Embodiments of this disclosure filter a set of key performance indicators (KPIs) based on various criteria to reduce the number of root causes that are considered when adjusting the wireless configuration parameters. In particular, the set of KPIs may be filtered based on various criteria. In one example, KPIs having a hit-ratio below a hit-ratio threshold are removed from the set of KPIs. In another example, KPIs having a slope of linear regression below a threshold slope are removed from the set of KPIs. In yet another example, a KPI is removed from the set of KPIs when a causal relationship between the KPI and another KPI in the set of KPIs exceeds a threshold. In yet another example, a KPI is removed from the set of KPIs when the KPI has a prediction impact score that fails to exceed a prediction impact threshold.
