**Cleanlab Issue Handler**

This Galaxy tool identifies and optionally removes or corrects data issues in supervised learning datasets using the [Cleanlab](https://cleanlab.io/) Python library. It supports **classification** and **regression** tasks and helps improve dataset quality by detecting label errors, outliers, near-duplicate entries, and non-IID samples.

The tool internally fits a cross-validated model (e.g., via XGBoost) to estimate label quality and identify problematic samples. These issues can be summarized in a report, and optionally addressed via removal or correction (depending on task and selected method).

--------------------

**Detected Issue Types (with technical examples)**

- **Label Issues**  
  These are samples whose label in the dataset is likely incorrect.
  **Example:** In a medical classification dataset, a patient's record is labeled as "benign," but its feature pattern is highly similar to correctly labeled "malignant" cases.


- **Outliers**  
  Points that are statistically distant from the rest of the dataset.  
  **Example**: An entry with unusually high or low feature values (e.g., several standard deviations away from the mean).

- **Near-Duplicates**  
  Highly similar or repeated samples.  
  **Example**: Two rows with nearly identical features and labels — possibly a duplication or copy artifact.

- **Non-IID Samples** *(classification only)*  
  Samples that violate the assumption of independent and identically distributed data.
  **Example**: A subset from a different population source (e.g., a different hospital or device) introducing distributional shift.

--------------------

**Parameters**

- **Input file**: Tabular file (CSV/TSV) with a `target` column.
- **Task type**: `classification` or `regression`.
- **Method**: `remove` (delete problematic rows) or `replace` (correct labels — classification only).
- **Only report issues**: If checked, input data is unchanged; only a summary report is produced.
- **Issue types**: Choose which issues to detect and handle.
- **Quality threshold** *(regression only)*: A float between 0.0 and 1.0 that determines how aggressively the tool flags low-quality labels in regression. Labels with quality scores below this threshold will be removed.

--------------------

**Outputs**

- **summary.txt**: Report listing each issue type, confidence score, and number of affected rows.
- **cleaned_data**: Cleaned dataset (CSV/TSV), only produced if "Only report issues" is unchecked.
