Abstract
Abstract Cervical cancer is a kind of common female malignancy ranking fourth for mortality worldwide. Traditional histopathological examination, an important diagnosis method of cervical cancer, is still manually performed by pathologists under the microscope, which is labor intensive and error‐prone. In this article, deep learning is used for whole slide cervical image (WSCI) analysis to explore an automatic and effective method for the diagnosis of cervical cancer. We combine convolutional neural network (CNN) and random forest (RF) classifier for whole slide cervical image classification. A new multilevel feature fusion strategy named Ensemble is used for features extraction from the features extracted by CNN. Ensemble that fuses features extracted by convolution layers with different depths in CNN together is capable of capturing fusional features which can describe patches at different levels from different convolutional layers. Principal component analysis (PCA) algorithm is introduced for feature reduction of the multilevel features. Our experiments are carried out on WSCI dataset which consists of a total of 163 WSCIs from 27 patients. We combine CNN + PCA + RF model and CNN + RF model, respectively, with four feature extraction strategies to conduct eight comparative experiments on the 163 WSCIs. Experimental results demonstrate that when using multilevel feature fusion strategy, the classification accuracy of the CNN + PCA + RF model reaches the highest to 99.39%. In addition, the CNN + PCA + RF model conducting the multilevel feature fusion strategy performs better than that conducting single‐level feature extraction strategies.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
