R-squared is a statistical measure that:

ACombines precision and recall of a classifier into a single metric by taking their harmonic mean.

BExpresses the extent to which two variables are linearly related.

CIs the proportion of the variance for a dependent variable thaf' s explained by independent variables.

DRepresents the extent to which two random variables vary together.

Show Suggested Answer

Suggested Answer: B

Workflow design patterns for machine learning pipelines are common solutions to recurring problems in building and managing machine learning workflows. One of these patterns is to represent a pipeline with a directed acyclic graph (DAG), which is a graph that consists of nodes and edges, where each node represents a step or task in the pipeline, and each edge represents a dependency or order between the tasks. A DAG has no cycles, meaning there is no way to start at one node and return to it by following the edges. A DAG can help visualize and organize the pipeline, as well as facilitate parallel execution, fault tolerance, and reproducibility.

This one seems straightforward - I think the answer is C, the proportion of variance explained by the independent variables.

Hmm, I'm a bit confused on the best way to link these data extensions. I'll have to review the Contact Builder documentation again.

I'm a little confused by the wording of this question. The "within limitations" part is throwing me off. I'm going to have to re-read the descriptions of each access control model to make sure I understand the differences.

Okay, let's see. I think Lead Routing, Lead Assignment Rules, and Einstein Lead Scoring are the three features that could be used here. I'll double-check my understanding before submitting my answer.

Hmm, D kind of sounds like it could be right, but C is more specific and detailed. I'll go with C.

I agree, C is the correct answer because it explains the proportion of variance in the dependent variable. Good choice.

I think D is more about the relationship between two variables, while C is about explaining variance. I'll choose C.

Option B seems to best capture the essence of R-squared. I'm leaning that way.
