c. Identifying a network data packet as dangerous (virus, hacker attack) based on comparison to other packets whose threat status is known.
d .Identifying segments of similar customer

Answer 1

Answer:

Supervised and Unsupervised Learning:

a. Unsupervised learning

b. Supervised learning

3. Supervised learning

4. Unsupervised learning

Explanation:

The key difference between supervised machine learning and unsupervised machine learning is that with supervised machine learning there is a training dataset (labeled data) on which the algorithm is trained to predict patterns.  With unsupervised machine learning on the other hand, there is no training data.  So, the algorithm discovers patterns on itself without reference to another labeled data or training dataset.
