In this question, we will try and understand 1 1 convolutional kernels and their functions: Given that the training mini - batch size is 3

In this question, we will try and understand 11 convolutional kernels and their functions:
Given that the training mini-batch size is 32 images, each of dimension 128128 pixels and 3
channels (Red, Blue, Green). Assume that we apply a single 11 convolutional filter with stride 1.
What will be the ratio between the size of the tensor before applying the filter and its size
after the application of the filter?
What is the interpretation of such a filter? Let us say we are designing a CNN to detect a
blue-colour Pepsi can. What would you expect the weights of the trained 11
convolutional filter to be like, when each of the weights are mapped to the 0-to-256
range? (Assume the convention of Red - Blue - Green for writing the weights). Marks: 7
Let us say the prior layer of your network has size 3232256(i.e. Height x Width x
Depth, where depth denotes the number of convolutional filters used). Compare the
following two scenarios in terms of the parameters that need to be trained.
Scenario A: Kernel of size 33, with stride of 1 and 256 such filters (i.e.256 activation
maps).
Scenario B:
Previous Layer - Size 32*32*256
Conv (11 kernel), stride 1,64 such filters
Conv (33 kernel), stride 1,64 such filters
Conv (1 x 1 kernel), stride 1,256 such filters
What will be the total number of parameters and the final size of the tensor after the
application of convolutional filters in the two scenarios?
How are these two scenarios comparable?
