Rado Rabemananjara contributed to the NNPDF/nnpdf repository by developing and refining data processing pipelines, hyperparameter optimization modules, and plotting utilities for physics data analysis. He implemented robust uncertainty data handling and standardized metadata across datasets, improving data fidelity and reducing misconfigurations. Using Python, YAML, and Pandas, Rado enhanced compatibility with evolving dependencies like Matplotlib and PineAPPL, ensuring reliable visualization and analysis workflows. His work on the HyperLoss module introduced new loss functions and improved reward calculations, supporting more precise model tuning. Throughout, he emphasized maintainable code, commit-level traceability, and workflow automation, demonstrating depth in scientific computing and DevOps.

For 2025-08, delivered the Chi2p Loss Function for Hyper-Optimization in NNPDF/nnpdf, expanding the loss options and integrating its calculation into the HyperLoss class to enable finer model tuning and metric-based optimization. There were no major bugs fixed this month; the focus was on feature delivery, integration, and code quality. Overall, this work strengthens the model selection pipeline by providing a richer optimization signal, enabling more reliable hyperparameter searches and potential gains in generalization. Technologies demonstrated include Python-based metric integration, modular hyper-optimization workflows, and version-control discipline (e.g., clear commit history).
