abstract = "The asteroidal main belt is crossed by a web of mean-motion and
secular resonances, that occur when there is a commensurability
between fundamental frequencies of the asteroids and planets.
Traditionally, these objects were identified by visual inspection
of the time evolution of their resonant argument, which is a
combination of orbital elements of the asteroid and the perturbing
planet(s). Since the population of asteroids affected by these
resonances is, in some cases, of the order of several thousand,
this has become a taxing task for a human observer. Recent works
used Convolutional Neural Networks (CNN) models to perform these
tasks automatically. Here, we compare the outcome of such models
with those of some of the most advanced and publicly available CNN
architectures, like the VGG, Inception and ResNet. The performance
of these models is first tested and optimized for overfitting
issues, using validation sets and a series of regularization
techniques like data augmentation, dropout, and batch
normalization. The three best-performing models were then used to
predict the labels of larger testing databases containing
thousands of images. The VGG model, with and without
regularizations, proved to be the most efficient method to predict
labels of large datasets. Applications of such methods to
asteroids interacting with secular and mean-motion resonances,
like the \ν6 and M1:2 exterior resonance with Mars, already
produced significant discoveries, like the identification of the
(12988) Tiffanykapler asteroid family. This is the first young
asteroid family ever found in a linear secular resonance, for
which precise estimates of both the age and the ejection velocity
field can be obtained. Since the Vera C. Rubin observatory is
likely to discover up to four million new asteroids in the next
few years, the use of CNN models might become quite valuable to
identify populations of resonant minor bodies.",
