In Search of Missing Collection: The Case of Artist Albert Rappaport
Bibliographic record
Abstract
Summary The artist Albert Rappaport was born in Anykščiai in 1898. In 1911, the family emigrated to New York. Rappaport became an American citizen in 1925 and began to travel widely. He studied fine art in New York, Paris, Dresden and Munich. He visited South America, Africa and traveled extensively through Europe (1925–1927, 1933, 1937–1939), returning to the United States now and again. The artist participated in several dozen exhibitions. He showed his work in Paris, Rome, Florence, Barcelona, Palma de Mallorca, Copenhagen, Mexico City, Havana, New York, Calgary and Montreal, in addition to his solo exhibitions in 1937 in Warsaw and Vilnius, and in Kaunas, Riga and Tallinn in 1938. After Rappaport’s death, in March 17, 1969 in Montreal, his collection of artworks disappeared and has thus far not been found. To date, two of his painted portraits are known to exist – one belongs to the private collection of Jonathan C. Rappaport, another is on display at the Jewish Public Library in Montreal.

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.
