Colorectal cancer pathogenesis investigation method based on artificial intelligence

Abstract

The invention discloses a colorectal cancer pathogenesis investigation method based on artificial intelligence. According to the method, patient data are collected through questionnaires and diagnosis and treatment records, the obtained data are preprocessed, noisy point data are removed, unoccupied data are supplemented, and multi-valued data are processed through a sparse matrix projection method. Through a feature selection and feature dimension reduction method, in combination with the influence degree of the features on the illness probability, features with low influence degree are removed, and then in combination with medical feature features, features with high importance are selected. And finally, inputting the data into an artificial intelligence algorithm, and compared with the accuracy of traditional algorithms such as linear regression, a support vector machine, a BP neural network, naive Bayes and random forest, selecting the algorithm with the highest accuracy, and then performing parameter adjustment to improve the accuracy so as to obtain the relationship between the specific characteristic index and the cancer risk.

Description

technical field [0001] The invention relates to the field of medical data analysis, in particular to an artificial intelligence-based method for investigating the cause of colorectal cancer. Background technique [0002] Malignant tumor (cancer) is one of the main threats to human life and health. While cancer is harmful to the life safety of patients, it also brings a heavy psychological burden to patients and their relatives. The high cost of cancer treatment brings huge burdens to patients. Economic pressure, so that there is a saying in Chinese society that "talking about cancer turns pale". The National Cancer Center pointed out in the 2019 National Cancer Report that in 2015, about 3.929 million people in China were diagnosed with malignant tumors, and 2.338 million people died of cancer, and the incidence of cancer has maintained an increase of about 3.9% in the past ten years. . Colorectal cancer is the third most common cancer in China, and its incidence rate is s...

Problems solved by technology

[0003] At present, the screening methods for colorectal cancer are mainly digital rectal examination and colonoscopy, but due to the importance of related examinations has not attracted people's attention, or economic conditions do not allow, the early screening of colorectal cancer is currently The ideal effect of preventing the disease has not yet been achieved
