- B . Market competition only
- C . Technical feasibility, cost, and time constraints
- D . Preferred communication channels of the project manager
Which statement best differentiates machine learning from deep learning?

- B . Deep learning algorithms require less data to learn.
- C . Machine learning models are always transparent, whereas deep learning models cannot be interpreted.
- D . Deep learning algorithms are a subset of machine learning algorithms that do not require feature engineering.
Given the Confusion matrix below, which is the formula for specificity?
- A . TN/(TN + FP)
- B . TP/(FP + TP)

- B . The dataset size is extremely large.
- C . Only the model’s accuracy matters.
- D . The data is completely balanced.
Cloud Pak for Data’s integration with Spark allows users to:
- A . Perform complex computations on small datasets only
- B . Leverage distributed computing for processing large datasets efficiently
- C . Avoid using any form of data processing or analysis

What is data leakage in the context of model training?
- A . When data from outside the training dataset is accidentally included in the training process
- B . A situation where the test data is not available
- C . Leakage of sensitive information due to poor data handling practices
- D . Loss of data during the splitting process
Which statistical method reduces the number of attributes by lumping highly correlated attributes together?
