# What is deep-rl?

We have a tag for but it has no wiki and I'm not really sure what it is. Can anyone shed light on this?

• Deep reinforcement learning, I assume? The approach that beats people in Go, etc. – amoeba Feb 7 '18 at 7:53
• The tag was created here: Why does Q-Learning use epsilon-greedy during testing? That supports @amoeba's guess. Another issue is what to do about the tag. – gung - Reinstate Monica Feb 7 '18 at 12:17
• "Deep RL" is a standard term in the deep RL community, so I'm pretty sure that's what it is. I can write an excerpt, but we can also replace all 9 instances with [deep-learning] + [reinforcement-learning]. @gung – amoeba Feb 7 '18 at 12:28
• @amoeba Thanks for doing the legwork! But there is a touch of tautology to the statement "'Deep RL' is a standard term in the deep RL community." ;-) – Sycorax Feb 7 '18 at 16:08
• Tautology of touch! – amoeba Feb 8 '18 at 13:41
• (Zero hits on google? Seriously? It should be a book title or something.) – amoeba Feb 8 '18 at 13:42
• This includes stuff like deep Q networks, actor critic models, hybrid CNN-RL methods, but maybe not things like multi-armed bandits or monte carlo methods. – MachineEpsilon Feb 9 '18 at 3:29

• Do you want it made a synonym of [deep-learning] as well? – gung - Reinstate Monica Feb 8 '18 at 11:59
• @Sycorax we don't need [deep-learning]; it's a shame that even researchers use marketing terms (and, to make it worse, often introduce them). – Franck Dernoncourt Feb 11 '18 at 19:45
