Building Web Processing Services with Birdhouse
Bibliographic record
Abstract
The Web Processing Service (WPS) is an OGC interface standard to provide processing tools as Web Service. The WPS interface standardizes the way processes and their inputs/outputs are described, how a client can request the execution of a process, and how the output from a process is handled. Birdhouse tools enable you to build your own customised WPS compute service in support of remote climate data analysis. Birdhouse offers you: A Cookiecutter template to create your own WPS compute service. An Ansible script to deploy a full-stack WPS service. A Python library, Birdy, suitable for Jupyter notebooks to interact with WPS compute services. An OWS security proxy, Twitcher, to provide access control to WPS compute services. Birdhouse uses the PyWPS Python implementation of the Web Processing Service standard. PyWPS is part of the OSGeo project. The Birdhouse tools are used by several partners and projects. A Web Processing Service will be used in the Copernicus Climate Change Service (C3S) to provide subsetting operations on climate model data (CMIP5, CORDEX) as a service to the Climate Data Store (CDS). The Canadian non profit organization Ouranos is using a Web Processing Service to provide climate indices calculation to be used remotely from Jupyter notebooks. In this session we want to show how a Web Processing Service can be used with the Freva evaluation system. Freva plugins can be made available as processes in a Web Processing Service. These plugins can be run using a standard WPS client from a terminal and Jupyter notebooks with remote access to the Freva system. We want to emphasise the integrational aspects of the Birdhouse tools: supporting existing processing frameworks to add a standardized web service for remote computation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
