Bayesian optimization is an effective tool to optimize black-box functions and popular for hyper-parameter tuning in machine learning.
Neural Diffusion Distance for Image Segmentation
To compute high-resolution diffusion distance or segmentation mask, we design an up-sampling strategy by feature-attentional interpolation which can be learned when training spec-diff-net.
