1. Introduction to Machine Learning with Keras

Activity 1.01: Adding Regularization to the Model

In this activity, we will utilize the same logistic regression model from the scikit-learn package. This time, however, we will add regularization to the model and search for the optimum regularization parameter - a process often called hyperparameter tuning. After training the models, we will test the predictions and compare the model evaluation metrics to the ones that were produced by the baseline model and the model without regularization.

  1. Load the feature data from Exercise 1.03, Appropriate Representation of the Data, and the target data from Exercise 1.02, Cleaning the Data:
    import pandas as pd
    feats = pd.read_csv('../data/OSI_feats_e3.csv')
    target = pd.read_csv('../data/OSI_target_e2.csv')
  2. Create a test and train dataset. Train the data using the training dataset. This time, however, use part of the training dataset for validation in order to choose...
