Скачать или смотреть Uncertainty Estimation for Image Segmentation using Monte Carlo Dropout | PyTorch Tutorial

In this tutorial, we’ll explore how to estimate uncertainty in image segmentation using Monte Carlo Dropout (MC Dropout) with a U-Net model in PyTorch. Without retraining, we'll inject dropout layers at inference time and visualize uncertainty maps that reveal where the model is confident — and where it isn't.

This technique is especially useful in sensitive domains like medical imaging, agriculture, and autonomous driving, where model confidence is as important as prediction accuracy.
