Expert writing Tips

Best practice

When describing the process of evaluating a machine learning model, use "testing instance" to refer to a specific data point used for assessment. Ensure the context clearly indicates the stage of testing within the model development lifecycle.

Common error

Avoid using "testing instance" when a more general term like "example" or "case" would suffice. Overusing technical jargon can make your writing less accessible. Use it when referring to a specific data element in the testing or validation phase.

Linguistic Context

The phrase "testing instance" functions as a noun phrase, typically acting as the subject or object within a sentence. According to Ludwig, this term appears in contexts where specific examples are being assessed or evaluated.

FAQs

How can I use "testing instance" in a sentence?

Use "testing instance" to refer to a specific example or data point used for testing a model or system. For example, "Each "testing instance" is evaluated to determine the overall accuracy of the algorithm."

What is a good alternative to "testing instance"?

Depending on the context, you could use "test case", "sample data point", or "evaluation example". Each emphasizes a slightly different aspect of the testing process.

What does "testing instance" refer to in machine learning?

In machine learning, a "testing instance" typically refers to a single data point from a "test dataset" used to evaluate the performance of a trained model.

How does a "testing instance" differ from a "training instance"?

A "training instance" is used to train a model, while a "testing instance" is used to evaluate its performance on unseen data. The key difference is that "testing instance" helps to assess how well the model generalizes.
