Describe the differences between supervised and unsupervised learning in AI.

• Supervised learning uses labeled data, while unsupervised learning uses unlabeled data.

• Supervised learning is faster than unsupervised learning.

• Unsupervised learning requires labeled data, while supervised learning does not.

• There is no difference between supervised and unsupervised learning.

Artificial neural networks have helped with machine learning by:

• improving data processing capabilities

• reducing computational costs

• eliminating the need for data

• increasing hardware requirements

A search engine uses machine learning to improve its performance by:

• analyzing user behavior to refine search algorithms

• increasing the number of indexed pages

• reducing server load

• improving hardware infrastructure

In supervised learning, what is required for the system to be trained?

• Labeled data

• Unlabeled data

• Reinforcement signals

• No data

Unsupervised learning is a type of machine learning where:

• The model is trained on labeled data

• The model is trained on unlabeled data

• The model is trained with supervision

• The model is trained with reinforcement

The basis of learning in Reinforcement Learning is:

• Supervised learning

• Unsupervised learning

• Trial and error

• Genetic algorithms

Unlabelled data is used more in semi-supervised learning because:

• it is cheaper and easier to obtain than labeled data.

• it provides more accurate results than labeled data.

• it requires less computational power.

• it is more reliable than labeled data.

Which of the following is a feature used in face recognition?

• Distance between the eyes

• Color of the eyes

• Hair length

• Skin tone

Deep learning is used for ______ in the context of image recognition.

• enhancing image quality

• detecting objects

• improving color accuracy

• reducing noise

List the two tools used by Computer-Assisted Translation (CAT) as described in the passage.

• Translation Memory and Machine Translation

• Grammar Checker and Spell Checker

• Text Editor and Word Processor
