Bonobos use a kind of syntax once thought to be unique to humans

> They recorded over 300 of these observations, including what the caller was doing at the time, what was happening in the environment and the behaviour of the caller and audience after the vocalisation.

This is lots of manual effort, could the recent advancement in language models help decode animal languages more easily? I guess it will need lots 24/7 capture of physical movement/action and sound data and train a model (that already understands vocal English too) perhaps.

I definitely think you’re touching on some exciting possibilities, but adding a language model at this early stage would endanger the goal of this particular research: proving that the compositionality exists in the first place. If there was a foundational language model we’re involved, it might be reading patterns into the calls regardless of whether they’re really there — that is what it’s designed to do, after all!

Re:”lots of work”, I think you’re misunderstanding the quotes a bit. They applied PCA to categorical data to generate semantic positions for each call type—or, in other words, ran a prewritten mathy algo on a big csv. Collecting the CSV data in the first place certainly sounds extremely hard, but that’s more of a practical issue than a scientific one! Bonobos aren’t known for living in easy-to-reach places ;)
