+Completely randomly.
+

+
+When are Convolutional Neural Networks not useful?
+
+## --answers--
+
+If your data can't be made to look like an image, or if you can rearrange elements of your data and it's still just as useful.
+
+---
+
+If your data is made up of different 2D or 3D images.
+
+---
+
+If your data is text or sound based.

+## --text--
+
+Why is it better to calculate the gradient (slope) directly rather than numerically?
+
+## --answers--
+
+It is computationally expensive to go back through the entire neural network and adjust the weights for each layer of the neural network.
+
+---
+
+It is more accurate.
+
+---
+
+There is no difference between the two methods.
