The United States Postal Service seeks public comment on proposed revisions to the service standards for certain market-dominant mail products. The Postal Service proposes to restructure the service standards, such that service standards for domestic First-Class Mail would retain the current day range of 1-5 days (as well as the current 0-1 days for USPS Connect[supreg] Local), while being calculated, with certain exceptions, as the sum of delivery days accruing across three successive operational legs reflecting end-to-end service from an originating 5-digit ZIP Code to a destinating 5-digit

An improved active learning method has been devised for training data classifiers. One example of a data classifier is the algorithm used by the United States Postal Service since the 1960s to recognize scans of handwritten digits for processing zip codes. Active learning algorithms enable rapid training with minimal investment of time on the part of human experts to provide training examples consisting of correctly classified (labeled) input data. They function by identifying which examples would be most profitable for a human expert to label. The goal is to maximize classifier accuracy while minimizing the number of examples the expert must label. Although there are several well-established methods for active learning, they may not operate well when irrelevant examples are present in the data set. That is, they may select an item for labeling that the expert simply cannot assign to any of the valid classes. In the context of classifying handwritten digits, the irrelevant items may include stray marks, smudges, and mis-scans. Querying the expert about these items results in wasted time or erroneous labels, if the expert is forced to assign the item to one of the valid classes. In contrast, the new algorithm provides a specific mechanism for avoiding querying the irrelevant items. This algorithm has two components: an active learner (which could be a conventional active learning algorithm) and a relevance classifier. The combination of these components yields a method, denote
