Abstract
About a century ago, one memorable night in April 1912, a world-shattering event happened. The Titanic, the 2,240-passenger luxury cruise ship, sank forever off the coast of Newfoundland in the North Atlantic after extensive damage to its hull by an iceberg on its maiden voyage. Only 705 people survived this disaster. Although nearly a century has passed, the research on Titanic has never stopped, and there are still many studies on it. This study was supposed to predict the survival of passengers on Titanic using different methods based on data from the Kaggle competition "Titanic: Machine Learning from Disaster." It predicted each passenger in the test set who would survive the sinking. The result was the percentage of correct prediction. In the Machine Learning study, the task is to achieve 80% accuracy in predicting the survival distribution of the Titanic disaster based on the demographic data testing notebook by different algorithms models. Using classification is the main point to calculate the efficiency achieved by those models through the test environment. The f-measurement scores obtained from the machine learning technology were in comparison with the f-measurement scores obtained by Kaggle.

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.
