NEW QUESTION # 31
A data scientist is working with a data set that has ten predictors and wants to use only the predictors that most influence the results. Which of the following models would be the best for the data scientist to use?
Answer: C
Explanation:
LASSO regression uses an L1 penalty that drives less‐important feature coefficients to exactly zero, effectively selecting only the predictors that most influence the outcome.
NEW QUESTION # 32
Which of the following JOINS would generate the largest amount of data?
Answer: C
Explanation:
A CROSS JOIN produces the Cartesian product of the two tables (every row from the first paired with every row from the second), yielding far more rows than any of the other join types.
NEW QUESTION # 33
Which of the following explains back propagation?
Answer: A
Explanation:
Back propagation computes the gradient of the loss (error) with respect to each weight by propagating the error signal backward through the network, then uses those gradients to adjust weights and biases.
NEW QUESTION # 34
A data scientist has constructed a model that meets the minimum performance requirements specified in the proposal for a prediction project. The data scientist thinks the model's accuracy should be improved, but the proposed deadline is approaching. Which of the following actions should the data scientist take first?
Answer: C
Explanation:
Since the model already meets the agreed-upon requirements and the deadline is near, the first step is to confirm with the stakeholder whether pursuing further accuracy gains is worth the additional time and resources. This ensures you align with business priorities before collecting more data, requesting funding, or tweaking the model further.
NEW QUESTION # 35
Which of the following modeling tools is appropriate for solving a scheduling problem?
Answer: D
Explanation:
Scheduling problems require finding the best allocation of resources subject to constraints (e.g., time slots, resource availability), which is precisely what constrained optimization algorithms are designed to handle.
