Using X-ray Image Processing Techniques to Improve Pneumonia Diagnosis based on Machine Learning Algorithms
Bibliographic record
Abstract
the diagnosis of chest disease depends in most cases on the complex grouping of clinical data and images. According to this complexity, the debate is increased between researchers and doctors about the efficient and accurate method for chest disease prediction. The purpose of this research is to enhance the first handling of the patient data to get a prior diagnosis of the disease. The main problem in such diagnosis is the quality and quantity of the images.In this paper such problem is solved by utilizing some methods of preprocessing such as augmentation and segmentation. In addition are experimenting different machine learning techniques for feature selection and classification.The experiments have been conducted on three different data sets. As the results showed, the recognition accuracy using SVM algorithm in the classification stage, the VGG16 model for feature extraction, and LDA for dimension reduction is 67% without using image pre-processing techniques, by applying pre-processing the accuracy increased to 89%. Using a two-layer NN the recognition accuracy is 69.3%. For the same model, the accuracy has increased with the addition of image pre-processing techniques to reach 96%.

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.
