Identification of Optimal Clustering Conditions
Optimal clustering conditions were determined using multiple validity indices across various time intervals, highlighting the effectiveness of monthly aggregated data and K=2 clusters for stable and accurate predictions.
Optimizing Cluster Parameters
Challenge: Identifying the most effective number of clusters (K) and data aggregation intervals for stable and accurate predictions in residential energy consumption, avoiding arbitrary selection.
Solution: Utilized Elbow-Method, Silhouette Score, Calinski-Harabasz Index, and Dunn Index across five data collection intervals (10 min, 1h, 1 day, 1 week, 1 month). Performed 10-run stability checks for cluster size variation.
Result: Optimal clustering achieved with K=2 (142 houses for C0, 206 houses for C1) using monthly resampled power data. This provided higher validity scores and stable partitions, crucial for downstream modeling. CatBoost and LightGBM consistently showed highest average prediction performance within these clusters.
