为了深入理解Python机器学习中的随机森林，我们将使用UCI Heart Disease数据集作为入门案例。数据集包含1000行14列，前13列是特征，最后一列是目标变量，表示是否患有心脏病。首先，确保数据集已从Heart Disease UCI下载，并为CSV格式。我们使用Google Sheets预览数据内容。数据导入的准备工作需要进行，将数据...
Coronary heart disease (CHD) is a serious cardiovascular disease (CVD)1that not only has a high mortality rate but also patients are prone to the risk of recurrence even after they are cured and discharged from the hospital, both of which are prognosis-oriented factors for poor outcomes. The...
The heart, which is the first organ to develop, is highly dependent on its form to function1,2. However, how diverse cardiac cell types spatially coordinate to create the complex morphological structures that are crucial for heart function remains u
Resting heart rate is associated with cardiovascular diseases and mortality in observational and Mendelian randomization studies. The aims of this study are to extend the number of resting heart rate associated genetic variants and to obtain further insights in resting heart rate biology and its clinica...
Our goal was to validate HR-PPG, measured using a smartphone app, against HR-electrocardiogram (ECG) measurements and describe out-of-clinic, real-world, HR-PPG values according to age, demographics, body mass index, physical activity level, and disease. To validate the measurements, we ...
Congenital heart disease (CHD) affecting the conotruncal region of the heart, occurs in 40–50% of patients with 22q11.2 deletion syndrome (22q11.2DS). This syndrome is a rare disorder with relative genetic homogeneity that can facilitate identification

In the stages of predicting the heart disease, the classifier is the fourth stage which is significant stage for achieving accuracy, sensitivity, and specificity. When k-means neighbour classification is compared, the ideology titled heart diseases prediction very early using improved k-means neighbour...
