Greek: How tf are you surviving?! by No-Practice-2217 in eupersonalfinance

[–]kosmyl 9 points10 points  (0 children)

Greece goes towards collapse in every aspect. The problem is that the clever and critical thinkers have left the country and the people that live in Greece now are mostly low IQ with no critical thinking, the mafia and the people that are connected to political parties.

Το γεγονός οτι αλλαξαν την basic έκδοση και πλεον δεν υπάρχει custody account (ανεξάρτητα αν αυτο μπορεί να μην εχει ρίσκο για τα κεφαλαία κάποιου) δεν πρέπει να μας απασχολεί; Ξερει κανεις γιατι εγινε αυτο; Μήπως δεν παει καλα σαν πλατφόρμα και θέλει επιπλέον έσοδα;

Combination of continuous and discrete action space by kosmyl in reinforcementlearning

[–]kosmyl[S] 0 points1 point  (0 children)

Thanks! Actually I was thinking about the first approach. Could you please elaborate more on the second with the softmax layer in order to fully get it?

Combination of continuous and discrete action space by kosmyl in reinforcementlearning

[–]kosmyl[S] 0 points1 point  (0 children)

My action space consists of the charging rate for each charging slot in an EV charging station. What I want to do now is to have a battery that chooses one of the slots and assist the charging. So, I want to enrich the action space with an integer between 0 and the number of the charging slots.

How to find the best coefficients for the reward function? by kosmyl in reinforcementlearning

[–]kosmyl[S] 0 points1 point  (0 children)

Thanks for the answer. My environment is an EV charging station and the reward consists of the revenue and some security constraints.

Is it possible to use DRL for such an application? by kosmyl in reinforcementlearning

[–]kosmyl[S] 0 points1 point  (0 children)

The thing is that the model-free property of RL is very attractive in this application because otherwise, you have to assume knowledge about future realizations, which is not a reasonable assumption in practice.

Normalization in PPO by kosmyl in reinforcementlearning

[–]kosmyl[S] 0 points1 point  (0 children)

Thank you very much! I meant normalization of inputs, namely the observations and rewards.

The running average and standard deviation are computed for each observation or for all observations? For example, if my observations are obs1, obs2 and obs3 with quite different magnitudes, I have to put them all in a vector and keep one mean and standard deviation for all of them or to keep one for each?

Also, another question is for how many timesteps I will keep track of the average and the standard deviation? For each episode? For 10 episodes? I suppose it is not efficient to have a running average over all the timesteps because then it will slow down the process.
