# How should continuous outputs be in convolutional neural network?

I have labeled faces images (label is the age -continuous value-) dataset and I want to construct a Convolutional Neural Network model to predict the age of a person.

I have the following questions.

• How the label i.e. the age must be encoded ?
• Which activation function to use ?
• yes, in fact i have another outputs (ethnicity and gender) and its okay for them, but i still have a problem with age, i don't know if i have to do some modifications in age encoding or in the neural net layers! Feb 27 '19 at 9:47
