Detection of Erythropoietin in Blood to Uncover Doping in Sports using Machine Learning
Bibliographic record
Abstract
Sports officials around the world are facing challenges due to the unfair nature of doping practices used by unscrupulous athletes to improve their performance. This prac-tice includes blood transfusion, intake of anabolic steroids or even hormone-based drugs like erythropoietin to increase their strength, endurance, and ultimately their performance. While direct detection and identification of erythropoietin in blood samples of athletes have proven an effective means to uncover doping, not all the cases are easily detectable, and some analyses are too costly to be carried out on every sample. This leads to a need to develop an indirect method for detecting erythropoietin in blood samples based on different blood biomarkers. In this paper, we presented a comparison of different machine learning algorithms combined with statistical analysis approaches to identify the presence of erythropoietin drug in blood samples collected at both sea level and moderate altitude. The results presented indicate that ensemble methods like random forest and X Gboost algorithms may provide an effective tool to aid anti-doping organisations in most effectively distributing scarce resources. Implementation of these methods on the samples from elite athletes may both enhance the deterrence effect of anti-doping as well as increases the likelihood of catching doped athletes.

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.
