Ants Learn Geometry and Features [PDF]

open access: yesCurrent Biology, 2009
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).

Multiview Deep Feature Learning Network for SAR Automatic Target Recognition

open access: yesRemote Sensing, 2021
Multiview synthetic aperture radar (SAR) images contain much richer information for automatic target recognition (ATR) than a single-view one. It is desirable to establish a reasonable multiview ATR scheme and design effective ATR algorithm to thoroughly

Feature Discovery by Competitive Learning* [PDF]

open access: yesCognitive Science, 1985
This paper reports the results of our studies with an unsupervised learning paradigm which we have called “Competitive Learning.” We have examined competitive learning using both computer simulation and formal analysis and have found that when it is applied to parallel networks of neuron‐like elements, many potentially useful learning tasks can be ...
