Can we ask for an intuitive explanation of models, algorithms, and topics related to Artificial Intelligence and Deep Learning?
Yes, you can ask for an intuitive explanation of a model, algorithm or, in general, topic. Just make sure that you clarify in your post what exactly you are looking for.
For example, if you're looking for an intuitive explanation of how a u-net works, you should ask
Intuitively, how does u-net work? What are the main ideas behind this model?
If you just ask
How does u-net work?
a person could think that you are looking for a detailed explanation (and that could even considered a too broad post). Alternatively, if you are (also) looking for a detailed explanation, you may (also) ask for a reference that explains the topic in detail.
Moreover, before asking a question, you should probably do a little bit of research on your own, then explain WHAT you haven't understood in the sources that you have researched/read so far (maybe you should also cite the sources that you have read).
