Scoring Agent

Scoring Algorithm Overview

Component Architecture

The Scoring Agent represents the analytical core of Kaizen AI, responsible for transforming multi-dimensional project data into actionable risk assessments through the proprietary Kaizen Score (0-100). This agent employs a sophisticated hybrid approach that combines rule-based logic with advanced machine learning models to deliver accurate, real-time risk evaluations for cryptocurrency projects.

Core Responsibilities:

• Multi-factor risk assessment across technical, economic, social, and governance dimensions

• Real-time score calculation and updates based on changing project conditions

• Machine learning model ensemble management and optimization

• Historical pattern recognition and predictive analytics

• Confidence interval calculation and uncertainty quantification

• Dynamic threshold adjustment based on market conditions

Scoring Philosophy: The Kaizen Score reflects the principle of continuous improvement by adapting to evolving threat patterns and market dynamics. The scoring system prioritizes transparency, reproducibility, and actionable insights, ensuring users understand both the score rationale and the confidence level of each assessment.
