3. In this question, you will implement logistic regression and one of the machine learning algorithm like KNN, DF or SVM algorithms from scratch, train and test with Breast Cancer Wisconsin Data in python. (40 point) Write logistic regression algorithm from scratch with python. Split data into train and test data set. Train data with training data set Test data with test data set and show accuracy. Explain each step, for example "I initialize weight as 0.01 because ..." or "I use sigmoid function because ..." you can write these as a "comment" in python. Do not use any logistic regression method from libraries. You can use numpy and pandas libraries or train test split method. Repeat these steps for the other machine learning algorithm you choose.
