Enum PNAScaler

Namespace

AiDotNet.Enums

Assembly

AiDotNet.dll

Scaler function types for Principal Neighbourhood Aggregation (PNA).

public enum PNAScaler

Fields

Amplification = 1

Amplification scaler - amplifies signal from high-degree nodes.

Attenuation = 2

Attenuation scaler - attenuates signal from high-degree nodes.

Identity = 0

Identity scaler - no scaling applied.

Remarks

For Beginners: Scalers normalize aggregated features by node degree:

• Identity: No scaling (use raw aggregated values)
• Amplification: Scale up by degree/avgDegree (high-degree nodes get amplified)
• Attenuation: Scale down by avgDegree/degree (high-degree nodes get attenuated)
