Hello,

Could anyone explain to me the role of the parameters of TEDPolicy number\_of\_transformer\_layers Parameter?

In fact, number\_of\_transformer\_layers has the following parameters: text, action\_text, label\_action\_text, dialogue.

What is the meaning of each param? what is the difference between action\_text and label\_action\_text?

Because from this video [Rasa Algorithm Whiteboard - TED Policy](https://www.youtube.com/watch?v=j90NvurJI4I&list=PL75e0qA87dlG-za8eLI6t0_Pbxafk-cxb&index=14), I understood that (intent, entity, slot, prev action) arrays are concatenated in a single array. Is this final array corresponding to the dialogue parameter?

I hope you might be able to give me some insights on this.

Thanks!
