What's the difference between the two terms? Don't they mean the same thing? They mean different things, and can occur in any combination. A known, deterministic environment This is an environment where the researcher knows how to calculate all the transitions in advance of observing them, and the transition from state $s$ given action $a$ is always to ...

Sorry for the delay. The term "vector-valued feedback" is compared to scalar-valued feedback. The implication (which I should have made explicit) is that, because vector-valued feedback tells the network the correct answer, the changes in weights required to improve performance are reasonably easy to calculate (e.g. using backprop). In contrast, if a ...

Yes. A computational linguist is someone who (among other things) uses computers to process/model/analyse/... natural language. Coding might be one aspect of it, but is about the least important: you can always get a non-linguist programmer to do coding for you. I studied "Computational Linguistics" at university, and while programming was taught as part of ...

A trajectory ist just a sequence of states and actions. In RL, the goal is to maximize the reward, by finding the right trajectories. $$ \operatorname{max}_\tau R(\tau) $$ This means maximizing not immediate reward (caused by one action from a state), but cumulative reward (all states and actions: trajectory)

CNNs, LSTMs, GRUs and transformers are or use artificial neural networks. The expression computational intelligence (CI) is often used interchangeably with artificial intelligence (AI). CI can also refer to a subfield or superfield of AI where biology is often an inspiration. See What is Computational Intelligence and what could it become? by Włodzisław Duch....
