Ants Learn Geometry and Features
Rats trained to relocate a particular corner in a rectangular arena systematically confound the correct corner and the diametrically opposite one--this rotational error demonstrates the use of the geometry of space (i.e., the spatial arrangement of the different components of a visual scene). In many cases, geometric information is preferentially used over other spatial cues, suggesting the pre...
متن کاملDesert Ants Learn Vibration and Magnetic Landmarks
The desert ants Cataglyphis navigate not only by path integration but also by using visual and olfactory landmarks to pinpoint the nest entrance. Here we show that Cataglyphis noda can additionally use magnetic and vibrational landmarks as nest-defining cues. The magnetic field may typically provide directional rather than positional information, and vibrational signals so far have been shown t...
متن کاملAnchorNet: A Weakly Supervised Network to Learn Geometry-sensitive Features For Semantic Matching Supplementary material
In this section we provide additional details about the learning protocol of AnchorNet. Training converges after visiting 4× 10 training samples (for each class) in stage 1 and 1.2×10 samples in stage 2 (two days on a single GPU NVIDIA Tesla M40). The learning rate was fixed to a value of 10 with the minibatch size of 16 and the momentum set to the standard value of 0.0005. The training data we...
متن کاملAnts Can Learn to Forage on One-Way Trails
The trails formed by many ant species between nest and food source are two-way roads on which outgoing and returning workers meet and touch each other all along. The way to get back home, after grasping a food load, is to take the same route on which they have arrived from the nest. In many species such trails are chemically marked by pheromones providing orientation cues for the ants to find t...
متن کاملDo wood ants learn sequences of visual stimuli?
The visually guided foraging routes of some formicine ants are individually stereotyped, suggesting the importance of visual learning in maintaining these routes. We ask here whether the wood ant Formica rufa learns a sequence of visual features encountered at different stages along a route, as reported for honeybees. We trained ants in several simple mazes to follow two alternative routes. Alo...
