dataeval.shift.ChunkResult¶ class dataeval.shift.ChunkResult¶ Result for a single chunk in chunked drift detection. key¶ Human-readable identifier for this chunk. Type:¶ str index¶ Sequential chunk index. Type:¶ int start_index¶ Start index in the original array (-1 for non-contiguous chunks). Type:¶ int end_index¶ End index (inclusive) in the original array (-1 for non-contiguous chunks). Type:¶ int value¶ Raw metric value for this chunk (e.g., mean distance, MMD^2, AUROC). Type:¶ float upper_threshold¶ Upper threshold bound. Exceeding this indicates drift. Type:¶ float or None lower_threshold¶ Lower threshold bound. Falling below this indicates anomaly. Type:¶ float or None drifted¶ Whether this chunk’s metric exceeds the threshold bounds. Type:¶ bool data()¶ Return the output data as a dictionary. Return type:¶ dict[str, Any] meta()¶ Metadata about the execution of the function or method for the Output class. Return type:¶ ExecutionMetadata
