Seek and learn: Automated identification of microevents in animal behaviour using envelopes of acceleration data and machine learning

open access: yesMethods in Ecology and Evolution, Volume 11, Issue 12, Page 1639-1651, December 2020., 2020
Abstract Animal‐borne accelerometers have been used across more than 120 species to infer biologically significant information such as energy expenditure and broad behavioural categories. While the accelerometer's high sensitivity to movement and fast response times present the unprecedented opportunity to resolve fine‐scale behaviour, leveraging this ...
