Deep Research Engine: Multi-LLM Talent Discovery from Facial Personality Analysis

Puntos clave

The aim is to develop an AI-driven system that accurately assesses children's personality traits through facial analysis.
Utilized a two-stage AI system for talent discovery from facial photographs.
Stage 1 involved extracting 137 personality traits using gradient boosting ensemble techniques.
Stage 2 utilized 5-25 parallel LLM agents for comprehensive talent profiling across 306 categories.
Achieved internal validation AUC of 0.81, indicating high accuracy.
Competed against human experts with AI correlation of 0.351 compared to experts' 0.291.
Facial analysis showed AUC of 0.82, outperforming traditional questionnaire AUC of 0.54.
Cost efficiency demonstrated at $0.041 per analysis, representing a significant reduction in costs.
External validation in banking demonstrated an AUC of 0.94 with over 5,000 evaluations.

Resumen

DEEP RESEARCH ENGINE: MULTI-LLM TALENT DISCOVERY FROM FACIAL PERSONALITY ANALYSIS PROBLEM & SIGNIFICANCE Traditional talent assessment in children costs 500-2, 000 per child and requires 2-3 hours of expert time, limiting access to privileged populations. This preprint presents a two-stage AI system achieving expert-level accuracy at 0. 041 per analysis. INNOVATION Stage 1: Deep Research Engine extracts 137 personality traits from facial photographs using gradient boosting ensemble (CatBoost 40%, XGBoost 35%, LightGBM 25%). Stage 2: Multi-LLM Talent Analyzer processes traits through 5-25 parallel LLM agents from diverse providers (OpenAI, Anthropic, Gemini, XAI) for comprehensive talent profiling across 306 categories. KEY RESULTS - Internal Validation: AUC 0. 81 95% CI: 0. 78-0. 84 - Human Expert Comparison: AI r=0. 351 vs. Experts r=0. 291 (+6. 0%, p=0. 46) - Equal-Feature Baseline: Facial AUC=0. 82 vs. Questionnaire AUC=0. 54 - Cost Efficiency: 0. 041 per analysis (10, 000× reduction) - External Validation: Banking AUC 0. 94 (N>5, 000)
