Suppose you are using YOLO on a 19×19 grid, on a detection problem with 20 classes, and with 5 anchor boxes. During training, for each image you will need to construct an output volume y as the target value for the neural network; this corresponds to the last layer of the neural network. What is the dimension of this output volume?            a.19x19x(5×20)b.19x19x(5×25)c.19x19x(25×20)d.19x19x(20×25)

Solution

The dimension of the output volume in this case would be 19x19x(5x25). This is because for each grid cell, we have 5 anchor boxes and for each anchor box, we have 5 predictions (x, y, w, h, and objectness) plus 20 class probabilities. So, for each anchor box, we have 25 outputs. Therefore, the answer is b.19x19x(5x25).
