Question
You have an input volume that is 63x63x16, and convolve it with 32 filters that are each 7x7, using a stride of 2 and no padding. What is the output volume?Question 9Answera.29x29x32b.16x16x16c.16x16x32d.29x29x16
Solution
The output volume of a convolutional layer can be calculated using the formula:
(W−F+2P)/S+1
where:
- W is the input volume size (in this case, 63)
- F is the size of the filters used (in this case, 7)
- P is the padding applied (in this case, 0)
- S is the stride used (in this case, 2)
Substituting the given values into the formula, we get:
(63 - 7 + 2*0)/2 + 1 = 29
So, the spatial dimensions of the output volume would be 29x29.
Since we are using 32 filters, the depth of the output volume would be 32.
Therefore, the output volume would be 29x29x32. So, the correct answer is a.29x29x32.
