Werner, Rothmund-Thompson, and Bloom syndromes all present with characteristic cutaneous findings during childhood and a predisposition for highgrade osteosarcoma, often at unusual locations, such as the patella. Although each of these syndromes maps to a unique genetic locus, the gene products share significant sequence homology. The latter finding is intriguing given the clinical similarities...

Introduction: Bloom filters [1] are a space-efficient, probabilistic data structure for representing a list of elements (for example, a list of strings). A Bloom filter is an array of m bits. A string is mapped into a Bloom filter by inputting it to a group of k hash functions resulting in k array positions. Each indexed array position is set to 1. A string is tested for membership by inputting...

Recent work has suggested enhancing Bloom filters by using a pre-filter, based on applying machine learning to model the data set the Bloom filter is meant to represent. Here we model such learned Bloom filters, clarifying what guarantees can and cannot be associated with such a structure.
