Parity file
WebThis paper considers predictive parity, which requires equalizing the probability of success given a positive prediction among different protected groups. We prove that, if the overall performances of different groups vary only moderately, all fair Bayes-optimal classifiers under predictive parity are group-wise thresholding rules. WebFiles deleted before the next sync can create a "parity hole". So in your case, if you deleted one 1GB file you could effectively have 1GB of data that cannot be restored. That could result in multiple files corrupted because multiple blocks could be used from that deleted 1GB file to calculate parity for multiple other files.
