Besides providing a new predicted value, which additional task would some modeling nuggets perform?

The correct answer is C. Use the scored data to update itself to increase its accuracy. Some modeling nuggets - particularly those supporting online or adaptive learning (such as SPSS Modeler's Self-Learning Response Model) - can feed scored data back into themselves to incrementally retrain and improve over time. This self-updating behavior is what makes C…

Question

Besides providing a new predicted value, which additional task would some modeling nuggets perform?

Options

  • AProvide additional information regarding the quality of the prediction.
  • BFilter non-target fields from being passed downstream.
  • CUse the scored data to update itself to increase its accuracy.
  • DExport the predictions to external storage or processes for further use.

Explanation

Some modeling nuggets - particularly those supporting online or adaptive learning (such as SPSS Modeler's Self-Learning Response Model) - can feed scored data back into themselves to incrementally retrain and improve over time. This self-updating behavior is what makes C correct: beyond generating a prediction, these nuggets treat each scored record as new training input, closing the feedback loop automatically.

Why the distractors are wrong:

  • A is tempting but describes something nearly all modeling nuggets do (e.g., confidence scores) - not a capability unique to "some."
  • B describes field filtering, which is handled by other node types (like a Filter node), not a modeling nugget's scoring function.
  • D describes output/export behavior, which is the job of Export nodes downstream, not the modeling nugget itself.

Memory tip: Think of the word "some" in the question as your signal. Most nuggets score; only some also learn. If a nugget can update itself, it's doing more than predicting - it's adapting. Associate "self-updating model = online learning nugget" and you'll lock in C every time.
