In the lava stdp implementation are A+ and A- flipped from what they should be?

[Michaeljurado42]

Specifically, I am looking at this declaration of the STDP learning rule inside the tutorial:

In the tutorial they link a wiki page resource showing classic STDP hebbian learning:
.
Using a negative A+ does lead to weight increases according to this equation.

I notice that in the stdp tutorial they also flip the order of A+ and A- so the graph looks correct:

. In this example on_post_stdp is A-

I am not sure if this is an issue or an intentional choice which is why I made it a discussion post.

Hi @Michaeljurado24,

thanks for bringing that to our attention. I double checked and you are right indeed, the usage of Aplus and Aminus is flipped and this is not intended. We will correct that (@gkarray). It would be great if you could add an issue about this anyway, just to make sure it's not forgotten.

I just made an issue. Thanks for the reply!
