description = """# [Mosquito Alert Competition 2023](https://www.aicrowd.com/challenges/mosquitoalert-challenge-2023) - 7th Place Solution

Welcome to my Hugging Face Space showcasing the performance of our model. 

This competition focused on detecting and classifying various mosquito species. 

The target species were:
- **Aedes aegypti** - Species
- **Aedes albopictus** - Species
- **Anopheles** - Genus
- **Culex** - Genus (Species classification is challenging, so it is provided at the genus level)
- **Culiseta** - Genus
- **Aedes japonicus/Aedes koreicus** - Species complex (Differentiating between these two species is particularly challenging).

> ***Note:** Only one mosquito will be annotated even if there are multiple mosquitoes in the image.*

## Experiment Details

All the details regarding the experiments and source code for the models can be found in the [GitHub repository](https://github.com/HCA97/Mosquito-Classifiction/tree/main).
