Match each description to either Machine learning or Deep learning.
Deep learning | Machine learning | |
|---|---|---|
needs only a small amount of training data | ||
problems are solved in an end to end manner | ||
enables machines to make decisions with the help of artificial neural networks | ||
has clear rules to explain how decisions were made | ||
makes use of modular approach at design and training stages | ||
needs vast amounts of data during training and development | ||
enables machines to make decisions on their own based on past data | ||
makes decisions based on its own logic so the reasoning may be difficult to interpret |
