9 Commits • 3 Features
Nov 1, 2025November 2025 summary: Delivered unified data_source with value 'both' across EstimatorReports and displays to enable direct train-vs-test comparisons in ROC, precision-recall, prediction_error, and summary metrics. Extended data_source='both' support to RocCurveDisplay, EstimatorReport metrics, and ComparisonReport metrics, establishing consistent cross-dataset reporting and faster diagnostic insight. Fixed a confusion-matrix normalization issue by reverting an unintended metric accessor change, restoring correct display behavior. Improved test infrastructure and formatting, reducing test durations from ~45s to ~12s through simpler models and fixture reuse, and enhancing code readability across tests and fixtures. Demonstrated strong proficiency in Python data-modeling, visualization components, and test optimization, delivering tangible business value through reliable reporting and quicker feedback loops.

Oct 1, 2025October 2025 (2025-10) focused on user experience, data persistence, and data integrity in probabl-ai/skore. Delivered three key contributions: (1) improved Skore Hub login UX with clearer feedback and robust handling when auto-launch fails; (2) migrated the default local project workspace to the user data directory to ensure persistence across platforms, with accompanying docs/tests updates; (3) enhanced data integrity and efficiency by conditionally uploading permutation data only when computed and by updating the EstimatorReport protocol to include a _hash field. These changes reduce onboarding friction, improve cross-OS reliability, and strengthen reproducibility and traceability in model evaluation.

May 1, 2025May 2025: Enhanced cross-validation reporting and plotting in probabl-ai/skore. Implemented ROC and precision-recall curve plotting for cross-validation comparison reports with per-estimator curves, improved plotting API, and ensured chance level is displayed in legends. Refactored plotting internals to non-static methods and removed the ax parameter to simplify usage. Also delivered maintenance work: fixes to documentation links, prevented in-place mutations of cached DataFrames, and corrected a readability typo in the metrics error message. Extended Python compatibility to 3.13 by removing the upper bound in package configs, positioning the project for future Python versions and smoother onboarding.

Jan 1, 2025January 2025 monthly summary for probabl-ai/skore: Restored default non-HTML display behavior by reverting the HTML representation of Items across environments (Jupyter compatibility restored). Cleaned up and standardized the CrossValidation reporting API to reduce user confusion by promoting EstimatorReport/CrossValidationReport under a unified 'report' terminology and deprecating CrossValidationReporter. Improved documentation UX by reducing clutter (narrower left sidebar) and removing type hints from API docs for cleaner presentation. Implemented a storage optimization for NumpyArrayItem by switching from array.tolist() to numpy.save while preserving allow_pickle=False. These changes reduce maintenance burden, improve developer experience, and enhance performance and API clarity.
