PuTR-CouT: Counting-by-Tracking in Camera-Trap Image Sequences
Fagner Cunha, Juan G. Colonna, Eulanda M. dos Santos
Species identification in camera trap images has been widely studied, but key ecological modeling tasks such as species abundance or density estimation also require counting indivi…
Counting Animals in Camera-Traps Image Sequences without Count Labels: Winning Solution to the iWildCam 2021 Challenge
Fagner Cunha, Juan G. Colonna, Eulanda M. dos Santos
Camera traps have become an essential tool for wildlife monitoring, motivating the development of computer vision methods for the automated extraction of information from these dat…
Process Mining Embeddings: Learning Vector Representations for Petri Nets
Juan G. Colonna, Ahmed A. Fares, Márcio Duarte +1
Process Mining offers a powerful framework for uncovering, analyzing, and optimizing real-world business processes. Petri nets provide a versatile means of modeling process behavio…
Generative transformations and patterns in LLM-native approaches for software verification and falsification
Víctor A. Braberman, Flavia Bonomo-Braberman, Yiannis Charalambous +3
The emergence of prompting as the dominant paradigm for leveraging Large Language Models (LLMs) has led to a proliferation of LLM-native software, where application behavior arises…
Catastrophic Forgetting in Deep Learning: A Comprehensive Taxonomy
Everton L. Aleixo, Juan G. Colonna, Marco Cristo +1
Deep Learning models have achieved remarkable performance in tasks such as image classification or generation, often surpassing human accuracy. However, they can struggle to learn…
A note on improving the search of optimal prices in envy-free perfect matchings
Marcos Salvatierra, Juan G. Colonna, Mario Salvatierra +1
We present a method for finding envy-free prices in a combinatorial auction where the consumers' number coincides with that of distinct items for sale, each consumer can buy on…
Bag of Tricks for Long-Tail Visual Recognition of Animal Species in Camera-Trap Images
Fagner Cunha, Eulanda M. dos Santos, Juan G. Colonna
Camera traps are a method for monitoring wildlife and they collect a large number of pictures. The number of images collected of each species usually follows a long-tail distributi…
Filtering Empty Camera Trap Images in Embedded Systems
Fagner Cunha, Eulanda M. dos Santos, Raimundo Barreto +1
Monitoring wildlife through camera traps produces a massive amount of images, whose a significant portion does not contain animals, being later discarded. Embedding deep learning m…
Discriminative Singular Spectrum Classifier with Applications on Bioacoustic Signal Recognition
Bernardo B. Gatto, Juan G. Colonna, Eulanda M. dos Santos +2
Automatic analysis of bioacoustic signals is a fundamental tool to evaluate the vitality of our planet. Frogs and bees, for instance, may act like biological sensors providing info…
New Metrics for Learning Evaluation in Digital Education Platforms
Gabriel Leitão, Juan Colonna, Edwin Monteiro +2
Technology applied in education can provide great benefits and overcome challenges by facilitating access to learning objects anywhere and anytime. However, technology alone is not…
