Resumen
IN LINE WITH UNESCO HISTORIC URBAN LANDSCAPE APPROACH, THIS STUDY HIGHLIGHTS THE NEED FOR INTEGRATIVE TOOLS THAT CONNECT HERITAGE CONSERVATION WITH BROADER URBAN DEVELOPMENT DYNAMICS, BALANCING PRESERVATION AND GROWTH. WHILE SEVERAL MACHINE-LEARNING MODELS HAVE BEEN APPLIED TO ANALYSE THE DRIVERS OF URBAN CHANGE, THERE REMAINS A NEED FOR COMPARATIVE ANALYSES THAT ASSESS THEIR STRENGTHS, LIMITATIONS, AND POTENTIAL FOR COMBINED APPLICATIONS TAILORED TO SPECIFIC CONTEXTS. THIS STUDY AIMS TO COMPARE THE PREDICTIVE ACCURACY OF THREE LAND-USE CHANGE MODELS (RANDOM FOREST, LOGISTIC REGRESSION, AND RECURSIVE PARTITIONING REGRESSION TREES) IN ESTIMATING THE PROBABILITY OF LAND-USE TRANSITIONS, AS WELL AS THEIR INTERPRETATIVE CAPACITY TO IDENTIFY THE MAIN FACTORS DRIVING THESE CHANGES. USING DATA FROM THE BELLAVISTA NEIGHBORHOOD IN TOMÉ, CHILE, THE MODELS WERE ASSESSED THROUGH PREDICTION AND PERFORMANCE METRICS, PROBABILITY MAPS, AND AN ANALYSIS OF KEY DRIVING FACTORS. THE RESULTS UNDERSCORE THE POTENTIAL OF INTEGRATING PREDICTIVE (RANDOM FOREST) AND INTERPRETATIVE (LOGISTIC REGRESSION AND RECURSIVE PARTITIONING REGRESSION TREES) APPROACHES TO SUPPORT HERITAGE PLANNING. SPECIFICALLY, THE RESEARCH DEMONSTRATES HOW THESE MODELS CAN BE EFFECTIVELY COMBINED BY LEVERAGING THEIR RESPECTIVE STRENGTHS: EMPLOYING RANDOM FOREST FOR SPATIAL SIMULATIONS, LOGISTIC REGRESSION FOR IDENTIFYING ASSOCIATIVE FACTORS, AND RECURSIVE PARTITIONING REGRESSION TREES FOR GENERATING INTUITIVE DECISION RULES. OVERALL, THE STUDY SHOWS THAT LAND-USE CHANGE MODELS CONSTITUTE VALUABLE TOOLS FOR MANAGING URBAN TRANSFORMATION IN HERITAGE URBAN AREAS OF INTERMEDIATE CITIES.
