Dear MARMAM community, My co-authors and I are pleased to share with you our new paper entitled ‘’Auto machine learning tools to distinguish between two killer whale ecotypes’’, published in Marine Mammal Science.
The paper is open access and available online at https://doi.org/10.1111/mms.13177 Research-gate: https://www.researchgate.net/publication/383555876_Auto_machine_learning_tools_to_distinguish_between_two_killer_whale_ecotypes Abstract: In the northwestern Pacific Ocean, there are two ecotypes of killer whales: residents or R-type (fish-eaters) and transients or T-type (mammal-eaters). Most attempts to determine the morphological distinctions between these ecotypes were either based on descriptive variations or utilized approaches that were impractical due to their time-consuming nature or low accuracy. Machine learning algorithms, a subfield of artificial intelligence, show significant potential for image classification. The present study used auto machine learning to differentiate between the dorsal fins of these two killer whale ecotypes using raster images obtained through field surveys. Two auto machine learning platforms were employed: Edge Impulse and Google Cloud AutoML. Both platforms demonstrated high performance. The Edge Impulse platform achieved an accuracy of 93.06%, while the Google Cloud platform achieved an average accuracy of 98.17%. Results show that machine learning stands out as a vital tool for image classification, effectively differentiating ecotypes and confirming that the morphological distinctions between these two ecotypes are not subjective interpretations. Machine learning promises to expand in its uses as an innovative and affordable method for studying the characteristics of cetaceans. How to cite this paper: Ismail, M. E., Fedutin, I.
