5. Score Aggregation Framework

Metrics Computation Systems

The Score Aggregation Framework implements sophisticated algorithms for combining multiple analysis vectors into comprehensive risk metrics. The system utilizes weighted probabilistic models for score aggregation and risk assessment.

Scoring Configuration

WEIGHT_CONFIG = {
    'chain_analysis': 0.30,
    'sentiment': 0.25,
    'temporal': 0.25,
    'whale': 0.20
}

RISK_THRESHOLDS = {
    'low': 0.25,
    'medium': 0.50,
    'high': 0.75,
    'critical': 0.90
}

Implementation Details

class MetricCalculator:
    def __init__(
        self,
        update_interval: int = 60,
        metric_weights: Optional[Dict[str, float]] = None
    ):
        self.update_interval = update_interval
        self.metric_weights = metric_weights or {
            'chain': 0.4,
            'sentiment': 0.3,
            'market': 0.3
        }
        
        self.metric_history = defaultdict(list)

    async def calculate_metrics(
        self,
        token_address: str,
        chain_data: Dict,
        sentiment_data: Dict,
        market_data: Dict
    ) -> AggregatedMetrics:
        """Calculate aggregated metrics from multiple sources."""

Risk Assessment Mechanisms

The system implements sophisticated risk scoring algorithms:

RISK_SCORING = {
    'confidence_threshold': 0.7,
    'min_data_points': 30,
    'time_decay_factor': 0.95,
    'volatility_impact': 0.3
}

Score Calculation

async def _calculate_composite_score(
    self,
    chain_metrics: Dict[str, float],
    sentiment_metrics: Dict[str, float],
    market_metrics: Dict[str, float]
) -> float:
    """Calculate composite score from all metrics."""
    scores = {
        'chain': np.mean(list(chain_metrics.values())),
        'sentiment': np.mean(list(sentiment_metrics.values())),
        'market': np.mean(list(market_metrics.values()))
    }
    
    composite = sum(
        scores[key] * self.metric_weights[key]
        for key in scores
    )
    
    return float(composite)

Index Generation Pipeline

Configuration Parameters

INDEX_CONFIG = {
    'update_interval': 300,  # 5 minutes
    'smoothing_factor': 0.1,
    'history_length': 1440  # 24 hours
}

Implementation Example

class IndexGenerator:
    def __init__(
        self,
        smoothing_window: str = '6h',
        update_frequency: str = '5min'
    ):
        self.historical_data = pd.DataFrame({
            'timestamp': pd.date_range(
                start='2024-01-01',
                periods=1000,
                freq='5min'
            ),
            'composite_risk': np.random.random(1000),
            'trading_volume': np.random.random(1000) * 1000000,
            'price_changes': np.random.random(1000) * 0.1 - 0.05
        })
