# Do we have to use CNN for Deep Q Learning?

and then I noticed that they all use CNN as approximator. If deep learning has a broader definition than just CNN, can we use the term "Deep Q-Learning" on our model if we don't use CNN? or is there a more appropriate definition for that kind of Q-Learning model? for example, if my model only using deep fully-connected layer.

*it doesn't say explicitly Deep RL means CNN on RL, but it uses the DeepMind (that uses CNN) as an example on Deep Q-Learning
