Question: In a few sentences, explain why the structure of a neural network can affect results and describe what is true about recent progress in this area.

Sample answer: The structure of a neural network matters because design choices such as depth, width, and connections can change how well the model learns and generalizes. This area has also seen rapid experimentation and improvement, so it continues to evolve quickly as researchers try new designs for better performance.

Key points:

• Architecture choices can strongly affect model results.
• Different structures influence learning capacity and generalization.
• Neural network design has been changing quickly through ongoing innovation.

Rubric: The essay should explain that architecture influences performance and note that the field has experienced substantial recent innovation.
