It have some next steps into main project file Classification.Choose tutors.ipynb:
Make functions for calculate standard scale, sigmoid and log loss function:
Make evaluate and metric functions:
Then fit and evaluate result:
At the end it is need to predict on test data, save submission.csv and send to Kaggle.
