Similarity Identification of Southern Resident Killer Whale (SRKW) Call Types Under Sparse Sampling Using Siamese Neural Networks
Southern Resident Killer Whales (SRKW) are highly intelligent marine mammals facing extinction in the North Pacific. These whales emit three types of sounds: clicks, whistles, and pulsed calls, with 43 distinct pulsed call types known as their "dialects". However, due to limited and poor-q...
