Sniffer dogs may have rediscovered a lost population of Sumatran rhinos
Sumatran rhinos — hairy and noisy — were thought to have gone extinct from southern Sumatra for years. Then came the dogs. Recently, dogs with Working Dogs for Conservation have discovered what are believed to be several heaps of Sumatran rhino dung in Way Kambas National Park, located in the southern part of the Indonesian […]

plant_pol_vazquez: Vazquez & Simberloff plant-pollinator webs
Eight bipartite networks of plants and pollinators, from the Nahuel Huapi National Park and surrounding areas in Rio Negro, Argentina, from September 1999 to Feburary 2000. Edge weights represent the frequency of species interaction, and there is a common set of vertices across all eight webs.
This network has 144 nodes and 36 edges.

Semiparametric Learning from Open-Set Label Shift Data
We study the open-set label shift problem, where the test data may include a novel class absent from training. This setting is challenging because both the class proportions and the distribution of the novel class are not identifiable without extra assumptions. Existing approaches often rely on restrictive separability conditions, prior knowledge, or computationally infeasible procedures, and some may lack theoretical guarantees. We propose a semiparametric density ratio model framework that en…
