Accelerated clustering through locality-sensitive hashing
(Massachusetts Institute of Technology, 2012)
We obtain improved running times for two algorithms for clustering data: the expectation-maximization (EM) algorithm and Lloyd's algorithm. The EM algorithm is a heuristic for finding a mixture of k normal distributions ...
Modelling signal interactions with application to financial time series
(Massachusetts Institute of Technology, 2014)
In this thesis, we concern ourselves with the problem of reasoning over a set of objects evolving over time that are coupled through interaction structures that are themselves changing over time. We focus on inferring ...
PhysioMiner : a scalable cloud based framework for physiological waveform mining
(Massachusetts Institute of Technology, 2014)
This work presents PhysioMiner, a large scale machine learning and analytics framework for physiological waveform mining. It is a scalable and flexible solution for researchers and practitioners to build predictive models ...
Jelf : a web framework for automatic privacy policy enforcement
(Massachusetts Institute of Technology, 2014)
As people share more personal data on the web, it is increasingly important to correctly enforce policies on sensitive data. To address this problem, we have developed Jelf, a web framework that allows the programmer to ...
The design and implementation of NewsPeek : an interactive news gatherer for future communications systems
(Massachusetts Institute of Technology, 2018)
This thesis describes work done at the Architecture Machine Group at MIT in the field of Media Technology. An interface to a information intensive network is discussed and proposed. A prototype implementation of such an ...
