# What is the standard terminology for the output matrix of a hidden layer in a CNN?

The output of a hidden layer $$h_i$$ in a convolutional neural network is (generally) a 3D grid of values. These values are the outputs of the neurons of layer $$h_i$$. Is there a standard way to refer to this matrix of values?

• Is there some standard terminology for the matrix of values, something like 'activation matrix'. – sanso Jun 8 '19 at 11:33
