We fit the model twice with this dataset: once using a de novo alignment and once using a template-based alignment with the first slice as the template. For both alignments, the warped coordinates were aligned with minimal distortion using the latent CCS (Fig. 1b). The MSEs for the de ...
We can fit and evaluate a Gaussian Processes Classifier model using repeated stratified k-fold cross-validation via the RepeatedStratifiedKFold class. We will use 10 folds and three repeats in the test harness.We will use the default configuration.1 2 3 ... # create the model model = ...

A default spread is calculated to fit the function to the minimum and maximum of the input dataset. The Gaussian function is useful when the highest preference is near a specific value. The Gaussian function is similar to the Near function, except the Near function has a narrower spread and ...

Note: In practice, whenNis large and when the image dimensions are large, we may not be able to compute all alphas and transmittance in one shot since the intermediate values may not fit within GPU memory limits. In such a scenario, it might be beneficial to compute the alphas and transmi...
