# qiskit\_noise\_learning.protocols.process\_learning\_result

`qiskit_noise_learning.protocols.process_learning_result(result: QuantumProgramResult, raw_data_stage: AnalysisStage | None = None) → Fit`

[GitHub](https://github.com/Qiskit/qiskit-noise-learning/tree/stable/0.1/qiskit_noise_learning/protocols/process_learning_result.py)

Analyze the result of a program built by [`prepare_learning_program()`](/docs/api/qiskit-noise-learning/generated/protocols-prepare-learning-program "qiskit_noise_learning.protocols.prepare_learning_program").

Applies the standard “vanilla” learning program analysis using curve fitting and [`LegacySolve`](/docs/api/qiskit-noise-learning/generated/analysis-legacy-solve "qiskit_noise_learning.analysis.LegacySolve") fit the model.

Example:

```python
fit = process_learning_result(job.result())
noise_maps = split_pauli_lindblad_model(fit.model).model.to_pauli_lindblad_maps(
    fit.model_data
)
```

**Parameters**

- **result** – The result of a program built by [`prepare_learning_program()`](/docs/api/qiskit-noise-learning/generated/protocols-prepare-learning-program "qiskit_noise_learning.protocols.prepare_learning_program").
- **raw\_data\_stage** – An optional analysis stage to run on the raw data ahead of the standard analysis, typically to post-select on registers that a pass manager added during preparation. It must consume and produce [`RawData`](/docs/api/qiskit-noise-learning/generated/data-raw-data "qiskit_noise_learning.data.RawData").

**Returns**

The fit, holding the data at every analysis level.

**Raises**

- [**TypeError**](https://docs.python.org/3/builtins/exceptions.html#TypeError) – If *raw\_data\_stage* is not an analysis stage.
- [**ValueError**](https://docs.python.org/3/builtins/exceptions.html#ValueError) – If *raw\_data\_stage* does not consume and produce [`RawData`](/docs/api/qiskit-noise-learning/generated/data-raw-data "qiskit_noise_learning.data.RawData"), if *result* holds no program items, if the result’s passthrough data was written in an incompatible format version, or if the result violates the solver’s assumptions.
