"Parameter sharing" $-$ A benefit of using convolutional networks. Which of the following statements about parameter sharing in CNN are true? a$.$ It allows a feature detector to be used in multiple locations throughout the whole input image$/$input volume. b$.$ More than one option is correct c$.$ It allows parameters learned for one task to be shared even for a different task $($transfer learning$).$ d$.$ It reduces the total number of parameters, thus reducing overfitting.
