I will need to analyze some soundscape data from Norway and it is likely that bats are present in the area. I was wondering if there was any available model trained for bat detection or ideally bat classification. I am aware of BatDetective but the github repository only provide the training / validation data. While it would be possible to retrain a model with the data provided on the BatDetective github, I would rather use a state-of-the-art bat detector / classifier.

To be clear I am not looking for a software such as mentioned in this post but I am rather interested in the raw model weights so I can have a greater coding flexibility.

    $\begingroup$ I edited and added that the soundscape data comes from Norway. However, any model would be helpful! $\endgroup$

Not sure if this fits your desire for a "state-of-the-art" detector, but it looks like BatDetective actually does have model weights available, just a bit hidden. If you download the "data" zip file from this website. There is a Pickle'd model "test_set_bulgaria.mod" within the models folder. There are also two sets of model weights saved here as .npy files.

If you have some of your own labeled training data then I would guess that one of those weights will probably be a decent starting place, or at least better than starting from scratch.
