description="The model predicts whether an image is a map or not. It takes about 30 seconds since it runs on a CPU (it is much faster on a GPU). Although the validation accuracy of the model is 98.5%, some outputs may not be correct. In this case, feel free to contact <a href='https://schnuerer.dev/contact'>me</a>.", |
