I had the exact same reaction: biology or computers?

The only hint I can see anywhere on the page is "Statistics > Machine Learning" above the abstract title.

I really want it to be about actual biological trees being studied on the scale of forests growing with smooth edges over long periods of time, but I suspect that's not what it is about.

There's also "Subjects: Machine Learning (stat.ML); Machine Learning (cs.LG)"

Also, the very first sentence of the actual paper (after the abstract) is

> Random forests (Breiman, 2001) have emerged as one of the most reliable off-the-shelf supervised learning algorithms [...]

arxiv.org is overwhelmingly used for math and computer science papers, though not exclusively.

The paper will also likely be submitted to a machine learning venue.

Biological trees don’t make predictions. Second or third sentence contains the phrase “randomized tree ensembles not only make predictions.”

Even single cells are able to sense and adapt to their environment. That is to recognize and react.
