1. You have trained and tested a regression model, and plotted the predicted labels against the actual label values in the training and test data. The resulting chart shows strong correlation between the predicted labels and the training data, but the actual label values from the test data vary significantly from the predicted values. What can you conclude about your model? a. The model will generalize well. b. The model is under-fitted. c. The model is over-fitted. d. The model will work better as an unsupervised learning model
