Abstract

fetched live from OpenAlex

Machine learning is a multidisciplinary field combining statistics, computer science and artificial intelligence. This research finds a way to use machine learning to predict the chance of heart attack based on information about the patient. There are 13 features collected about each patient which are age, sex, cholesterol, chest pain type, maximum heart rate achieved, resting blood pressure, resting electrocardiographic results, fasting blood sugar, exercise-induced angina, previous peak, slope, number of major blood vessels, and thalassemia. The information of all the patients is put into a dataset. The dataset is split into two sets, one for training and another for validation. A computer model using a supervised learning algorithm is developed and trained to predict the chance of heart attack. During training, the training set is used for training the model, while the validation set is used for evaluating the accuracy of the model.

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 distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
