- TargetIDColumn
- Specify the target table column name that contains identifiers of the target table vectors.
- TargetFeatureColumns
- Specify the target table column names that contain features of the target table vectors.You can specify up to 2018 feature columns.
- RefIDColumn
- [Optional] Specify the reference table column name that contains identifiers of the reference table vectors.
- RefFeatureColumns
- [Optional] Specify the reference table column names that contain features of the reference table vectors.You can specify up to 2018 feature columns.
- DistanceMeasure
- [Optional] Specify the distance type to compute between the target and the reference vector:
- Cosine: Cosine distance between the target vector and the reference vector.
- Euclidean: Euclidean distance between the target vector and the reference vector.
- Manhattan: Manhattan distance between the target vector and the reference vector.
- TopK
- [Optional] Specify the maximum number of closest reference vectors to include in the output table for each target vector. The value k is an integer between 1 and 100. The default value is 10.
