Description: This heatmap encodes the frequency of AI method mentions per institute. Methods were extracted from aiEnhancements and mapped to a standardized taxonomy (NLP, predictive modeling, geospatial AI, computer vision, network analysis, generative design, causal/econometric ML, simulation, anomaly detection). Missing combinations are represented as 0. Key insights: Governance-oriented units (CPR, CRIS, EGOV) emphasize NLP, simulation, and network analysis; environment-focused units (EHS, INRA, INWEH, FLORES) show strong geospatial and predictive modeling; economics units (MERIT, WIDER) use causal/econometric ML. Recommendations: Build shared tooling in geospatial ML and NLP; cross-train institutes with low method diversity; establish repositories of reusable models.
