Short Answer

Relating Task Complexity to Data Volume

Question: Why would a neural network trained to classify if an image is taken indoors or outdoors likely require a different number of training examples than one trained to classify if an image contains a cat with black and white fur?

Sample answer: Classifying whether an image was taken indoors or outdoors is inherently easier for a neural network than identifying a cat with specific fur colors. According to machine learning principles, easier tasks can be learned with fewer training examples, so the indoor/outdoor task would require less data.

Key points:

  • The two tasks have different levels of difficulty.
  • Easier tasks require fewer training examples to learn.

Rubric: The answer must mention that the tasks have different inherent difficulty levels and state the rule that easier tasks can be learned with fewer training examples.
