3. You want to write a deep learning algorithm that correctly classifies the trees in Aldrich park. To test your algorithm you want to compute how accurate it is, that is, the proportion of the trees that it correctly identifies. You do this by randomly sampling the trees in Aldrich Park and then testing your algorithm, observing how many of the trees are correctly identified. Let Zi be equal to 1 if the ith tree is correctly classified and 0 otherwise, for i
