Randomized partition trees for exact nearest neighbor search
Sanjoy Dasgupta
Video in druga učna gradiva
Oznake: computer science;machine learning
The k-d tree was one of the first spatial data structures proposed for nearest neighbor search. Its efficacy is diminished in high-dimensional spaces, but several variants, with randomization and overlapping cells, have proved to be successful in practice. We analyze three such schemes. We show that ...

Information Geometry
Sanjoy Dasgupta
Video in druga učna gradiva
Oznake: mathematics;statistics
This tutorial will focus on entropy, exponential families, and information projection. We'll start by seeing the sense in which entropy is the only reasonable definition of randomness. We will then use entropy to motivate exponential families of distributions — which include the ubiquitous Gaussian, ...

Analysis of Clustering Procedures
Sanjoy Dasgupta
Video in druga učna gradiva
Oznake: computer science;machine learning;clustering
Clustering procedures are notoriously short on rigorous guarantees. In this tutorial, I will cover some of the types of analysis that have been applied to clustering, and emphasize open problems that remain. Part I. Approximation algorithms for clustering Two popular cost functions for clustering ar ...

Active Learning
Sanjoy Dasgupta , John Langford
Video in druga učna gradiva
Oznake: computer science;machine learning;active learning
Active learning is defined by contrast to the passive model of supervised learning where all the labels for learning are obtained without reference to the learning algorithm, while in active learning the learner interactively chooses which data points to label. The hope of active learning is that in ...
