I study machine listening methods for bioacoustics and automated sensing of natural environments. And I enjoy natural environments. https://johnmartinsson.org/ Core member of Climate AI Nordics | ML researcher at RISEhttps://bsky.app/profile/johnmartinsson.orghttps://bsky.app/profile/johnmartinsson.org/post/3lzxxti2mds2uOur paper, “The Accuracy Cost of Weakness: A Theoretical Analysis of Fixed-Segment Weak Labeling for Events in Time”, is now out in TMLR! It explores tradeoffs in weak labeling for sound events and gives a theoretical basis for adaptive approaches. 📄 Read: https://johnmartinsson.org/publications/2025/the-accuracy-cost-of-weakness29 Sep 2025 12:05 +0000at://did:plc:prf6otntmwibo54xfopmxfdc/app.bsky.feed.post/3lzxxti2mds2uhttps://bsky.app/profile/johnmartinsson.org/post/3lrbhcyt45k2tSmall webpage for an ongoing #bioacoustic monitoring project I am part of at Stora Karlsö: auklab-audio.github.io Adding #audio will hopefully let us learn more about the life of the Guillemots. What are they saying? Lesson learned: designing a recording setup is a challenge and lots of fun! 🔊 https://auklab-audio.github.io/10 Jun 2025 17:49 +0000at://did:plc:prf6otntmwibo54xfopmxfdc/app.bsky.feed.post/3lrbhcyt45k2thttps://bsky.app/profile/johnmartinsson.org/post/3lnk43wupws2pFor years I've had a long-term personal goal to have a project in my work that requires me to do fieldwork. Early this year I achieved that goal. And this weekend I will go to Stora Karlsö and install microphones in a Guillemot colony with my collegues @mogren.ml @delialia.bsky.social. 🐧24 Apr 2025 06:42 +0000at://did:plc:prf6otntmwibo54xfopmxfdc/app.bsky.feed.post/3lnk43wupws2phttps://bsky.app/profile/johnmartinsson.org/post/3li5v7kaess2cPart of micing up a Guillemot colony in the Baltic Sea (www.balticseabird.com/auklab/). Switches with ethernet and power within 5 meters of all mics. Dynamic range important. Any tips on hardware (e.g multi channel ADC rack and mics, IP audio) and things to consider are welcome! #bioacoustics http://www.balticseabird.com/auklab/14 Feb 2025 19:00 +0000at://did:plc:prf6otntmwibo54xfopmxfdc/app.bsky.feed.post/3li5v7kaess2chttps://bsky.app/profile/johnmartinsson.org/post/3lhhe6kxcqc22Happy to be part of the core team for Climate AI Nordics!

Especially happy about the little clickable animal icons in the top. Click on a few to make a soundscape! #Bioacoustics #MachineLearning #MachineListening10 Dec 2024 15:36 +0000at://did:plc:prf6otntmwibo54xfopmxfdc/app.bsky.feed.post/3lcxl23dx722qhttps://bsky.app/profile/johnmartinsson.org/post/3lcfpjpyuhk2gFor anyone fascinated by technology, sound, and life itself, I highly recommend The Sounds of Life by the late Karen Bakker. This book explores how technology is unveiling the hidden sonic worlds of animals, transforming our understanding of nature’s communication.03 Dec 2024 13:09 +0000at://did:plc:prf6otntmwibo54xfopmxfdc/app.bsky.feed.post/3lcfpjpyuhk2g
