I'm not too familiar with ML, do you have to "train" tensorflow as to what audio in the data is "definitely a chainsaw" and which is "definitely a logging truck", etc etc? As in, you should keep doing this every now and then as you get more and more data, at least in the sense of flagging false positives (so as to unlearn that particular sound).

Yes. In the video there is a short snippet where the audio is shown as a Fourier transformed image on the screen and a user is annotating the image of the sound using red boxes. This is a part of the process to train the ML model to recognize chainsaw sounds vs. other sounds.

But can it identify lyrebird's?

If a lyrebird is mimicking a chainsaw or truck, wouldn't that indicate the presence of those chainsaws and trucks?

lyrebirds are native to Australia

Or they could legitimately be trying to make the world a better place along with making money. I know, naive right?

Yeah it's pretty naive. Google trying to make the world a better place would actually be illegal and would place the managers in jail for defrauding investors. Google's mission is to make as much money as possible, typical tactics include creating a good corporate image.

No google mission is to maximize shareholder value.

Making the world a better place increases shareholder value and is therefore compatible with their mission ;-)

Thanks for checking out Rainforest Connection! Seems that there are lots of [appropriate] questions about how well this works in the forest, and how our partners on the ground follow up on alerts. Here’s a recent intervention in Peru that sums up the process: https://twitter.com/lilitjejauregui/status/97585519352188518...

This technology is really cool. My question would be, "What happens when your AI detects chainsaws or logging trucks?". Do you contact some policy authority, some international authority? Also, why are their cell phone towers in the middle of the jungle? What about areas deep in the wilderness where no cell towers exist?

Anyone else wonder if google's on a massive PR drive given all the privacy-related bad press that tech has been getting recently?

I don’t think so. Google is massive and people that work there have been doing lots of different research for a very long time. OP has nothing to do with the past days of Facebook stuff IMO.

I had to look this up because I though you were jesting. Turns out Lyrebirds can mimic nearly any complex sound: https://youtu.be/VjE0Kdfos4Y

I imagine it would depend on the lifespan, and travel patterns of a lyrebird, no? Eg, bird is making the chainsaw noise weeks or years after the loggers have gone, possibly in an entirely different area.
