Pattern recognition in Spiking Neural Nets using Brian2

Good evening, Dear Brian2 Users,

I wanted to know, has this problem solved?

Here(on implementation result) as you can see STDP weights don’t show as expected behaviour like the paper result.

Because that might be the reason for my current problems: firstly, even though I sent 150 circle images for the training phase, all are not firing. Secondly, I really struggled to find the Brian2 function to give input data(change input data) in a given time {15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19,5, 20, 21, 23, 24, 24.5}* seconds. But I used my own implementation. In addition to that, I run the simulation in ms not seconds, because of the previous post issue. However, when I change input data following time ranges, my testing data should be only 13, but in my case, I’m getting 23, what would be the reason?

  1. Does Brian2 have a function that can have the functionality to sent(change) data in a specific (given) time during the simulation?

Thank you!
