In our paper we have used Logistic regression to the data set of size around 1200 patient data and achieved an accuracy of 89% to the problem of identifying whether the breast cancer tumor is cancerous or not. Keywords: breast cancer, mammograms, prediction, logistic regression, factors 1. The first example is related to a single-variate binary classification problem. However, this time we'll minimize the logistic loss and compare with scikit-learn's LogisticRegression (we've set C to a large value to disable regularization; more on this in Chapter 3!). Logistic LASSO regression based on BI-RADS descriptors and CDD showed better performance than SL in predicting the presence of breast cancer. This article is all about decoding the Logistic Regression algorithm using Gradient Descent. In this series we will learn about real world implementation of Artificial Intelligence.
