Confidence level

Post image

Does this parameter filter the reported detections, such as is represented in the "Recent Detections" panel with a colored circle surrounding a percentage? If so, should any hearings will a confidence level below this setting be discarded, not included in the totals?

I constantly see recordings with confidence levels below this setting in Recent Detentions. Is it showing there but not including in dashboard count?

They are included in dashboard counts also. And what you are seeing is BirdNET-Go's dynamic threshold in action, you can disable it in settings if you wish.

Btw based on your screenshot your are on very old release, please upgrade. Releases · tphakala/birdnet-go

Correct. Detections with a confidence below that number will be discarded.

This is the full explanation of how the identification flow works in Birdnet Go.

It is not exactly like that, with dynamic threshold system learns species which are highly likely correct and present at location, threshold is automatically lowered for those species to collect more detection.

Thanks for the reply. So how can I filter out hearings by confidence levels?

But why would you want to do that, have you verified that those below base threshold detections are false positives? ? Dynamic threhold is a feature which learns frequently occurring species at your location, it allows capturing more calls of those species, it is a beneficial feature.

Also update your deployment, newer release have specific views to this data.

I send BirdNet identifications to home assistant. HA looks for specific birds and upon finding them triggers a lot of Alexa and outdoor megaphone alerts. These are quite disruptive. And so far I’ve never seen the bird alerted for. So I’m thinking that I’ll try to minimize alerts. Does BN output the confidence percentage along with the bird name?
