October 2025 monthly performance summary for IBM/terratorch. Delivered targeted improvements to data visualization reliability and maintained stability by rolling back experimental data handling changes, while enhancing code quality and maintainability.

In September 2025, the Terratorch effort focused on delivering a more robust, scalable GeoBench data pipeline and improving installation ergonomics, culminating in substantial architectural upgrades and reliability gains for downstream ML workflows.

July 2025: Focused on restoring essential visualization capabilities to improve model interpretability and stakeholder communication for segmentation tasks. Re-enabled plotting for segmentation results in IBM/terratorch, addressing a regression and stabilizing the visualization flow. This contributed to faster analysis, better QA feedback, and clearer reporting of model behavior.

June 2025 — IBM/terratorch delivered a set of performance-focused features that improve training efficiency, data processing, and memory-footprint during inference. Key work includes sequential learning-rate scheduling with warmup/decay and a refactored optimizer factory, video data augmentation with multi-temporal support, GeoBench v2 wrappers with config-driven transforms and augmentation validation, and tiled inference for memory-efficient validation with robust device handling. The work also strengthened the data pipeline through input validation and added test coverage to validate scheduler and wrappers, reducing production risk and enabling scalable experiments.

May 2025 focused on enhancing benchmarking usability, expanding data integration, and modernizing ML pipelines across IBM/terratorch-iterate and IBM/terratorch. Delivered CLI-driven experiment summarization with configurable metrics and dynamic output naming, improved output organization, and updated storage/benchmark naming for better reproducibility. Addressed critical storage URI handling for the Multiclass Jaccard Index to ensure correct experiment references, and updated documentation to clarify hyperparameter optimization results and naming conventions. These changes improve reliability, traceability, and ease of use for end-to-end benchmarking and model evaluation across multimodal workflows.

April 2025 Monthly Summary for IBM/terratorch-iterate and IBM/terratorch. Focused on reducing external dependencies, expanding benchmarking flexibility, and enhancing the model training workflow. Key outcomes include self-contained benchmarking and plotting, dynamic module imports for the benchmarking CLI, and improved model training with better resource management. Additionally, Terratorch gained a flexible learning rate scheduling system with support for nested schedulers. These changes deliver faster experimentation cycles, lower operational risk, and better reproducibility across experiments.
