ML Feature Creation & Transformation Specialist

The Feature Engineering Agent executes Phase 3 (Feature Engineering, 5-second duration), transforming raw data into high-quality features for downstream ML models. It creates features across four types: NUMERIC (continuous values like age, income, engagement scores), CATEGORICAL (discrete categories like plan type, region, segment), EMBEDDING (vector representations for text and behavioral sequences), and TEMPORAL (time-based features like recency, seasonality, trends). The agent implements RFM analysis with O(n log n) complexity for customer value scoring, calculates feature importance scores for model explainability, tracks null rates to ensure data quality, and generates feature metadata for lineage tracking. It produces feature stores with standardized schemas, enabling consistent model training and inference. Healthcare-specific features include HEDIS measure flags, care gap indicators, SDoH factors, and engagement scores. Core capabilities include RFM analysis and scoring, categorical encoding, embedding generation, temporal feature extraction, feature importance calculation, and null rate tracking. Algorithms implemented include RFM Analysis with O(n log n) complexity for customer value scoring based on Recency, Frequency, Monetary metrics. Output types include feature stores, feature metadata, and importance rankings.
