1x1 Convolution: Demystified - Towards Data Science

https://towardsdatascience.com/1x1-convolution-5219bbc09027

1x1 convolution can be seen as an operation where a 1 x 1 x K sized filter is applied over the input and then weighted to generate F activation maps. F > K results in an increase in the filter dimension whereas F < K would cause an output with reduced filter dimensions. The value of F is quite dependent on the project requirement.
