Furthering decolonization and reconciliation via a portable planetarium
Bibliographic record
Abstract
The William J. McCallion Planetarium at McMaster University, Hamilton, Canada (established 1949), is pleased to share details of the first year of outreach initiatives and statistics from its new small (6m diameter) portable planetarium. The portable planetarium, purchased with funding from the Faculty of Science, was launched in June 2022, and has the primary goal of extending astronomy-based education and outreach initiatives to underserved and underrepresented communities off campus (to supplement the fixed planetarium on campus). The portable planetarium has also allowed us to continue our reconciliation efforts and astronomy collaborations with local Indigenous communities, resulting in the co-creation of one show and further shows in development. This presentation will highlight the co-creation process, successes and challenges we have experienced during our first months of operation, and will welcome conversations from communities we may be able to visit and/or from other institutes who currently have or are seeking to set up similar programs.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
