## Python implements logical regression and gradient descent strategy

We will build a logistic regression model to predict whether a student is admitted to the University. Suppose you are an administrator of a university department. You want to decide the admission opportunity of each applicant according to the results of two exams. You have the historical data of previous applicants, and you can use it as th ...
