I have two suggestions that you can look into. Based on my own work in RL, I believe the first one will require less work to implement. If the observability of the environment is not an issue, then you could give the agent a relative measure (distance to the goal) as part of the observation to provide it with knowledge of how far away it is. You can also ...

Predicting the correct amount of repetitions for an action sounds like a regression task. Turning it into a classification task using a model with n output nodes will lead to several drawbacks, the biggest ones being: Having to choose a priori a finite max amount of actions n Turning the data into really sparse vectors, especially for large n. So a better ...

The expression "number of actions" is being used in the same way in both cases. In fact, the letter $m$ is used in both cases. The number of actions (in the state $s$) is the number of possible actions that you can take in the state $s$. So, here, $m$ does not refer to the dimensionality of an action, but to the size of the action set for a state. ...

As I understand it, the Bellman equation assumes the setting to be deterministic, meaning that, if you're in state $s_t$ as you take action $a_1$, you should always reach the same $s_{t+1}$. This is not correct, which is a good thing for you. The Bellman equation for action values for an arbitrary policy $\pi(a|s): \mathcal{S} \times \mathcal{A} \rightarrow ...
