is a normality test based on the Kolmogorov–Smirnov test. It is used to test the null hypothesis that data come from a normally distributed population, when the null hypothesis does not specify which normal distribution; i.e., it does not specify the expected...
这是我学机器学习的一个项目,基于逻辑回归(Logistic Regression)的糖尿病视网膜病变(Diabetic Retinopathy)检测,该模型采用机器学习中逻辑回归的方式,训练Diabetic Retinopathy Debrecen Data Set的数据集,获得模型参数,建立预测模型,可以有效针对DR疾病做出预测和分类。仅供参考,莫要抄袭!!! 数据集 该数据集是从UCI机器学...
X -- data of size (num_px * num_px * 3, number of examples) Y -- true "label" vector (containing 0 if non-cat, 1 if cat) of size (1, number of examples) Return: cost -- negative log-likelihood cost for logistic regression dw -- gradient of the loss with respect to w, th...
Logistic regressionis a method forclassifying dataintodiscreteoutcomes. For example, we might use logistic regression to classify an email as spam or not spam. In this module, we introduce the notion ofclassification, thecost functionfor logistic regression, and theapplicationof logistic regression to...

Logistic regression (LR) is a machine-learning technique that can be used to make predictions on data where the dependent variable to be predicted takes a value of 0 or 1. Examples include predicting whether or not a patient will die due to heart disease within a certain number of years (...
Softmax Regression (synonyms: Multinomial Logistic, Maximum Entropy Classifier, or just Multi-class Logistic Regression) is a generalization of logistic regression that we can use for multi-class classification (under the assumption that the classes are mutually exclusive). In contrast, we use the (...
