Underwater & out of sight : towards ubiquity in underwater robotics
(Massachusetts Institute of Technology, 2019)
The Earth's oceans holds a wealth of information currently hidden from us. Eective measurement of its properties could provide a better understanding of our changing climate and insights into the creatures that inhabit its ...
Systems for collective human curation of online discussion
(Massachusetts Institute of Technology, 2019)
The internet was supposed to democratize discussion, allowing people from all walks of life to communicate with each other at scale. However, this vision has not been fully realized--instead online discourse seems to be ...
Reliably arranging objects : a conformant planning approach to robot manipulation
(Massachusetts Institute of Technology, 2019)
A crucial challenge in robotics is achieving reliable results in spite of sensing and control uncertainty. In this work, we explore the conformant planning approach to reliable robot manipulation. In particular, we tackle ...
Learning contact-aware robot controllers from mixed integer optimization
(Massachusetts Institute of Technology, 2019)
The problem of handling contact is central to the task of controlling a walking robot. Robots can only move through the world by exerting forces on their environment, and choosing where, when, and how to touch the world ...
Diversity-inducing probability measures for machine learning
(Massachusetts Institute of Technology, 2019)
Subset selection problems arise in machine learning within kernel approximation, experimental design, and numerous other applications. In such applications, one often seeks to select diverse subsets of items to represent ...
In-situ depth monitoring for a deep reactive ion etcher using a white light interferometer with active vibration cancellation
(Massachusetts Institute of Technology, 2019)
Standard process development for micro and nanofabrication etching technologies relies on open-loop trial and error testing of recipes to achieve optimal etch depths and uniformities. This strategy is inefficient for ...
Magnetic domain wall devices : from physics to system level application
(Massachusetts Institute of Technology, 2019)
Spintronics promises intriguing device paradigms where electron spin is used as the information token instead of its charge counterpart. Spin transfer torque-magnetic random access memory (STT-MRAM) is considered one of ...
Type system for resource bounds with type-preserving compilation
(Massachusetts Institute of Technology, 2019)
This thesis studies the problem of statically bounding the resource usage of computer programs, from programs written in high-level languages to those in assembly languages. Resource usage is an aspect of programs not ...
Building generative models over discrete structures : from graphical models to deep learning
(Massachusetts Institute of Technology, 2019)
The goal of this thesis is to investigate generative models over discrete structures, such as binary grids, alignments or arbitrary graphs. We focused on developing models easy to sample from, and we approached the task ...
Towards anonymous and metadata private communication at Internet scale
(Massachusetts Institute of Technology, 2019)
As the world becomes more connected, privacy is becoming harder to maintain. From social media services to Internet service providers to state-sponsored mass-surveillance programs, many outlets collect sensitive information ...
