Why did machine learning only become practical in the last few decades, even though the core ideas existed earlier?
Lack of data and computational resources
Lack of programming languages
ML wasn’t mathematically possible until the 2000s
Humans weren’t interested in automation
Why is it important to visualize data before fitting a regression model?
To check the beauty of the dataset
To detect relationships, outliers, and non-linear trends
To reduce training time
To automatically select features
Which of the following is a risk when increasing the polynomial degree in regression?
Underfitting
Perfect generalization
Overfitting
Improved interpretability
In what scenario would you prefer a high recall model over a high precision one?
Spam email filtering
Medical diagnosis of a rare but serious disease
Movie recommendation systems
Predicting daily weather temperature
What describe best gradient descent?
The weights move randomly with high temperature and slowly stop moving as temperature decreases
The slope starts vertically and then slowly goes down until a lowest loss is found
Weights are moving in the direction of the partial derivative of the loss toward a local minimum
This is an exact solver to find the global minimum of the loss
