a woman with skin lesions and brain infarcts we present the case of a 58yearold woman with multiple brain infarcts and livedo racemosa a distinctive branched and irregular skin discoloration on the trunk and limbs skin biopsy showed intimal proliferation with occlusion of a subcutaneous arteriole we diagnosed sneddons syndrome a rare neurocutaneous disorder likely caused by a noninflammatoryvasculopathy automatic pap mask sizing with an error correcting autoencoder we present the use of an error correcting autoencoder stage to a convolutional neural network model as a means of improving image based automatic positive airway pressure pap mask sizing accuracy a single convolutional layer neural network was pretrained using muct dataset and transfer learning was applied to mitigate against the relatively small custom dataset the base model was then augmented with an additional error correcting autoencoder and trained against the custom dataset the presented model increased pap sizing accuracy against the baseline by 153 while reducing overfitting
