Snakebite is the most deadly neglected tropical disease (NTD), being responsible for a dramatic humanitarian crisis in global health

Snakebite causes over 100,000 human deaths and 400,000 victims of disability and disfigurement globally every year. It affects poor and rural communities in developing countries, which host the highest venomous snake diversity and the highest burden of snakebite due to limited medical expertise and access to antivenoms

Antivenoms can be lifeโ€saving when correctly administered but this often depends on the correct taxonomic identification (i.e. family, genus, species) of the biting snake. Snake identification is also important for improving our understanding of snake diversity and distribution in a given area (i.e. snake ecology) as well as the impact of different snakes on human populations (e.g. snakebite epidemiology). But snake identification is challenging due to:

  • their high diversity
  • the incomplete or misleading information provided by snakebite victims
  • the lack of knowledge or resources in herpetology that healthcare professionals have

In this challenge we want to explore how Machine Learning can help with snake identification, in order to potentially reduce erroneous and delayed healthcare actions and improve snakebite eco-epidemiological data.

Task

In this challenge you will be provided with a dataset of RGB images of snakes, and their corresponding species (class) and geographic location (continent, country). The goal is to train a classification model.

The difficulty of the challenge relies on the dataset characteristics, as there might be a high intraclass variance for certain classes and a low interclass variance among others, as shown in the examples from the Datasets section. Also, the distribution of images between class is not equal for all classes: the class with the most images has 14,369 while the class with the fewest images has 17.

In round 3, you had 85 classes and 187,720 images. For round 4, we would like to make the barrier to entry much lower and demonstrate that the approach works well on 783 classes and 245,185 images. The idea is to renew the challenge every 4 months in order to get closer to our final goal, which is to build an algorithm which best predicts which antivenon should be given (if any) when given a specific image.

Datasets

Snakes are extremely diverse, and snake biologists continue to document & describe snake diversity, with an average of 30 new species described per year since the year 2000. Although most people probably think of snakes as a single โ€œkindโ€ of animal, humans are as evolutionarily close to whales as pythons are to rattlesnakes, so snakes in fact are very diverse! Taxonomically speaking, snakes are classified into 24 families, containing 528 genera and 3,709 species.

You can download the datasets in the Datasets Section. You are provided with a Train.tar.gz, file composed of 245,185 RGB images of varying size, split into 783 species.

Several aspects of snake morphology make this challenge more challenging:

Some species have patterns that vary depending on their age

Some species have patterns that vary depending on their location

Two species might look very similar, with one being venomous and the other not

The first iteration of the data set contains few such species, but we will add in more later.

Prizes

Note: To be eligible for these prizes, participants to the challenge will have to release their code under an open-source license of their choice

Timeline

This is the very first benchmarking challenge, meaning that it has no end date, but it will be updated every 3-4 months. Here is our next deadline:
