How weights are shared in CNN?
Table of Contents
Shared weights: In CNNs, each filter is replicated across the entire visual field. These replicated units share the same parameterization (weight vector and bias) and form a feature map. This means that all the neurons in a given convolutional layer respond to the same feature within their specific response field.
There are pure theoretical reasons for parameter sharing: It helps in applying the model to examples of different lengths. While reading a sequence, if RNN model uses different parameters for each step during training, it won’t generalize to unseen sequences of different lengths.
What does shared weights mean CNN?
Sharing weights among the features, make it easier and faster to CNN predict the correct image. It means that CNN use the weights of each feature in order to find the best model to make prediction, sharing the results and returning the average.
Why parameter sharing is a good idea for a convolutional layer?
Parameter sharing is used in all conv layer within the network. Parameter sharing reduces the training time; this is a direct advantage of the reduction of the number of weight updates that have to take place during backpropagation.
