IBM Data Science Practice Test

Which of the following is a benefit of supervised learning?

1. It works well with every type of data.

2. It allows for accurate predictions based on labeled data.

3. It requires little to no data preparation.

4. It reduces the need for consistency in data labeling.

The correct answer is: It allows for accurate predictions based on labeled data.

Supervised learning is a type of machine learning that utilizes labeled data to train algorithms, allowing them to make predictions or classifications based on that data. The primary benefit of supervised learning is its ability to create robust models that make accurate predictions when provided with unseen input data. The use of labeled data is essential in supervised learning; it provides the algorithm with a reference for the relationships and patterns that it needs to learn. By having clear input-output pairs during training, the algorithm learns to map specific features of the data to the correct output. This structured approach allows for better generalization to new, unseen examples, ultimately leading to higher accuracy when making predictions. While other options may suggest advantages or characteristics related to machine learning in general, they do not accurately represent the core benefits of supervised learning. The reliance on labeled data plays a crucial role in training the model effectively, which is why this answer stands out as the best response to the question regarding the benefits of supervised learning.
