Questions:

  1. How are artificial neural networks similar to the brain?    [Answer]

  2. What part of the artificial neural network is adjusted during the training process?   [Answer]

  3. When are neural networks a good choice for problem solving?   [Answer]

Use the JRec applet to answer the following questions.

  1. Choose Edit > Display Captured Images from the applet menu. Now draw a character and associated it with one of the digit buttons at the bottom of the applet. What do you notice in the window labeled "Downsampled inputs to network"? How do you think this might affect the performance of the applet? Train the network with some examples to test your hypothesis.

  2. Choose Network > Configure Network from the applet menu. Set the number of examples to five. You will also need to close the previous display window and reopen it. How do you think this configuration change will affect the performance of the applet? Train the network with some examples to test your hypothesis.

  3. Choose Network > Configure Network from the applet menu. Set the XSIZE and YSIZE to 15. Close and reopen the image display window to update the changes. How do you think this configuration change will affect the performance of the applet? Train the network with some examples to test your hypothesis.
