An automatic behavior recognition system classifies animal behaviors using movements and their temporal context

Primoz Ravbar, Kristin Branson, Jie H. Simpson
2019 Journal of Neuroscience Methods  
We use these spatiotemporal features in two steps of supervised classification that reflect two time-scales at which the behavior is structured.  ...  We applied this intuition to design a new automatic behavior recognition system (ABRS) based on spatiotemporal features in the video data, heavily weighted for temporal dynamics and invariant to the animal's  ...  It is key to point out that these are heuristics are based on the behaviors we have observed in wild-type flies, and that these corrections are applied in the last, optional curation step.  ...

Adaptive Text Recognition through Visual Matching [article]

2020 arXiv   pre-print
We introduce a new model that exploits the repetitive nature of characters in languages, and decouples the visual representation learning and linguistic modelling stages.  ...  By doing this, we turn text recognition into a shape matching problem, and thereby achieve generalization in appearance and flexibility in classes.  ...  This research is funded by a Google-DeepMind Graduate Scholarship and the EP-SRC Programme Grant Seebibyte EP/M013774/1.  ...

Yet, the absence of a unified evaluation for general visual representations hinders progress.  ...  Popular protocols are often too constrained (linear classification), limited in diversity (ImageNet, CIFAR, Pascal-VOC), or only weakly related to representation quality (ELBO, reconstruction error).  ...  To account for the training/evaluation stochasticity in VTAB, we sample (independently for every pair of model and task) one out of the three test-set repetitions, and compute the rank correlation between  ...
