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 ...
Shipboard condition based maintenance and integrated power system initiatives
(Massachusetts Institute of Technology, 2011)
With the U.S. Navy's continued focus on developing and implementing a robust integrated power system aboard future combatants, there has been an ever increasing effort to guarantee an electrical distribution system that ...
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 ...
Object localization and identification for autonomous operation of surface marine vehicles
(Massachusetts Institute of Technology, 2016)
A method for autonomous navigation of surface marine vehicles is developed A camera video stream is utilized as input to achieve object localization and identification by application of state-of-the-art Machine Learning ...
User-controlled privacy for personal mobile data
(Massachusetts Institute of Technology, 2014)
Smartphones collect a wide range of sensor data, ranging from the basic, such as location, accelerometer, and Bluetooth, to the more advanced, such as heart rate. Mobile apps on the Android and iOS platforms provide users ...
Complete VLSI implementation of improved low complexity chase Reed-Solomon decoders
(Massachusetts Institute of Technology, 2010)
This thesis presents a complete VLSI design of improved low complexity chase (LCC) decoders for Reed-Solomon (RS) codes. This is the first attempt in published research that implements LCC decoders at the circuit level. ...
DC to DC power conversion module for the all-electric ship
(Massachusetts Institute of Technology, 2011)
The MIT end to end electric ship model is being developed to study competing electric ship designs. This project produced a model of a Power Conversion Module (PCM)- 4, DC-to-DC converter which interfaces with the MIT ...
Efficient silicon micro-reactors for thermophotovoltaic applications
(Massachusetts Institute of Technology, 2011)
Thermophotovoltaic (TPV) systems passively generate electricity from the combustion of fuel. Although TPV conversion systems have advantages, they suffer from low efficiency. This thesis investigates different ways to ...
Autonomous adaptation and collaboration of unmanned vehicles for tracking submerged contacts
(Massachusetts Institute of Technology, 2012)
Autonomous operations are vital to future naval operations. Unmanned systems, including autonomous underwater vehicles (AUVs) and autonomous surface vehicles (ASVs), are anticipated to play a key role for critical tasks ...
