Plot losses
Once we've fit a model, we usually check the training loss curve to make sure it's flattened out. The history
returned from model.fit()
is a dictionary that has an entry, 'loss'
, which is the training loss. We want to ensure this has more or less flattened out at the end of our training.
This exercise is part of the course
Machine Learning for Finance in Python
Exercise instructions
- Plot the losses (
'loss'
) fromhistory.history
. - Set the title of the plot as the last loss from
history.history
, and round it to 6 digits.
