Details for method 'ENet with the Lovász-Softmax loss'
Method overview
| name | ENet with the Lovász-Softmax loss |
| challenge | pixel-level semantic labeling |
| details | The Lovász-Softmax loss is a novel surrogate for optimizing the IoU measure in neural networks. Here we finetune the weights provided by the authors of ENet (arXiv:1606.02147) with this loss, for 10'000 iterations on training dataset. The runtimes are unchanged with respect to the ENet architecture. |
