Abstract
Given two documents A and B we define two mathematical notions: their resemblance r(A, B) and their containment c(A, B) that seem to capture well the informal notions of "roughly the same" and "roughly contained." The basic idea is to reduce these issues to set intersection problems that can be easily evaluated by a process of random sampling that can be done independently for each document. Furthermore, the resemblance can be evaluated using a fixed size sample for each document. This paper discusses the mathematical properties of these measures and the efficient implementation of the sampling process using Rabin (1981) fingerprints.

Decentralized and Adaptive K-Means Clustering for Non-IID Data Using HyperLogLog Counters

TL;DR: This paper presents a decentralized and adaptive k-means algorithm that clusters data from multiple sources organized in peer-to-peer networks and addresses the challenge of decentralized clustering with skewed non-IID data and asynchronous computations by integrating HyperLogLog counters with k- means algorithm.

Routine Learning: from Reactive to Proactive Environments

TL;DR: The routine learning paradigm developed here can utilize already recognized contexts despite their meaning in the real world, and offers a step along the long road towards functional and calm intelligent environments.

A Sketch-based Sampling Algorithm on Sparse Data

TL;DR: This work proposes a sketch-based sampling algorithm, which effectively exploits the data sparsity and combines the advantages of both conventional random sampling and more modern randomized algorithms such as local sensitive hashing (LSH).

A Simulation Analysis of Redundancy and Reliability in Primary Storage Deduplication

TL;DR: Analysis of storage system reliability using public file system snapshots from two research groups shows that deduplication consistently reduces the damage of sector errors due to intra-file redundancy elimination, but potentially increases the damages of whole-disk failures if the highly referenced chunks are not carefully placed on disk.

Syntactic clustering of the Web

TL;DR: An efficient way to determine the syntactic similarity of files is developed and applied to every document on the World Wide Web, and a clustering of all the documents that are syntactically similar is built.

Min-Wise Independent Permutations

TL;DR: This research was motivated by the fact that such a family of permutations is essential to the algorithm used in practice by the AltaVista web index software to detect and filter near-duplicate documents.

Copy detection mechanisms for digital documents

TL;DR: This paper proposes a system for registering documents and then detecting copies, either complete copies or partial copies, and describes algorithms for such detection, and metrics required for evaluating detection mechanisms (covering accuracy, efficiency, and security).
