<p>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 <a href="https://github.com/macaodha/batdetect" rel="noreferrer">BatDetective</a> 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.</p>
<p>To be clear I am not looking for a software such as mentioned in <a href="https://bioacoustics.stackexchange.com/questions/469/what-are-the-automated-bat-identification-acoustics-tools-available">this post</a> but I am rather interested in the raw model weights so I can have a greater coding flexibility.</p>

Could you update with what geographic region you're looking at?

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

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](https://github.com/macaodha/batdetect) 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](https://bioacoustics.stackexchange.com/questions/469/what-are-the-automated-bat-identification-acoustics-tools-available) but I am rather interested in the raw model weights so I can have a greater coding flexibility.

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](http://visual.cs.ucl.ac.uk/pubs/batDetective/). There is a Pickle'd model "test\_set\_bulgaria.mod" within the models folder. There are also two sets of model weights saved [here](https://github.com/macaodha/batdetect/tree/master/bat_eval/models) 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.
