As we assume the response variable y to reside in the real continuous space for both regression and classification tasks, the code for training and inference of the diffusion models are the same (diffusion_utils.py file). The main differences are the handling of the f ϕ model (named self...
Supervised training of a binary classifier to detect a pathology and obtain a decision hyperplane. Calibrating a linear regression of the pathology grade to the hyperplane distance of embedded images.The method inherently enables the generation of counterfactual explanations (CEs), visualizing the model'...

(M_2\), then linearized to a 6205 dimensional vector and fed into a sigmoid function for classification. The cost function to optimize over is the sum of the logistic regression cross-entropy plus\(L_2\)penalty with parameter\(\lambda \). In TensorFlow, the range of parameters we cross-...

Here, we load an existing pretrained model/checkpoint and fine-tune it on our downstream task, which is a binary classification task (hence num_classes = 2). We could also fine-tune our model on regression tasks (num_classes = 1) or on multi-task classification. from...
In addition, the logistic regression model used in our method is learnt on the validation set. The thresholds of local classifiers and LR models for Multi-BS are tuned by performing 5-fold cross validation. Following the method in [16, 5], we choose the threshold which optimizes F1 score ...
