Abstract

In this article, we give an overview of efficient algorithms for the approximate and exact nearest neighbor problem. The goal is to preprocess a dataset of objects (e.g., images) so that later, given a new query object, one can quickly return the dataset object that is most similar to the query. The problem is of significant interest in a wide variety of areas.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Facebook reports that 'false' accounts are less prevalent in developed markets and more in developing markets.

    “The other three target one developed and two developing countries, as Facebook reports that 'false' accounts are less prevalent in developed markets and more in developing markets. 1”
  • The two-class SVM is the most effective in detecting like farm users compared to Decision Tree, AdaBoost, kNN, Random Forest, and Naïve Bayes.

    “We later compare this classifier with other well-known supervised classifiers such as Decision Tree [7], AdaBoost [20], kNN [1], Random Forest [6], and Na¨ ıve Bayes [55] and confirm that the two-class SVM is the most effective in detecting like farms users.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
