Distribution testing : classical and new paradigms
(Massachusetts Institute of Technology, 2020)
Hypothesis testing is a fundamental topic in statistics. To put it simply, hypothesis testing is a framework to examine whether a hypothesized model is in line with the observed data. Hypothesis testing has been widely ...
Exhaustive search and hardness proofs for games
(Massachusetts Institute of Technology, 2020)
This thesis explores several games from two perspectives: exhaustive search and hardness proofs. First, we present an exhaustive search for hardness proofs: a system for finding motion planning simulations. Second, we prove ...
Gen : a high-level programming platform for probabilistic inference
(Massachusetts Institute of Technology, 2020)
Probabilistic inference provides a powerful theoretical framework for engineering intelligent systems. However, diverse modeling approaches and inference algorithms are needed to navigate engineering tradeoffs between ...
Advances in deep generative modeling for clinical data
(Massachusetts Institute of Technology, 2020)
The intelligent use of electronic health record data opens up new opportunities to improve clinical care. Such data have the potential to uncover new sub-types of a disease, approximate the effect of a drug on a patient, ...
Learning to guide task and motion planning
(Massachusetts Institute of Technology, 2020)
How can we enable robots to efficiently reason both at the discrete task-level and the continuous motion-level to achieve high-level goals such as tidying up a room or constructing a building? This is a challenging problem ...
Trust less : shrinking the trusted parts of trusted systems
(Massachusetts Institute of Technology, 2020)
Modern computers, industrial control systems, and other automation are broadly vulnerable as a result of decades of systemic forces that have prioritized cost and performance over security. Computers across the board face ...
Strong and scalable metadata security for voice calls
(Massachusetts Institute of Technology, 2020)
This dissertation presents a scalable approach to protecting metadata (who is communicating with whom) in a communication system. The emphasis in this dissertation is on hiding metadata for voice calls, but the approach ...
Terahertz wave-molecule interactions via CMOS chips : from comb gas sensor with absolute specificity to ultra-stable, miniaturized clock
(Massachusetts Institute of Technology, 2020)
Under the excitation of electromagnetic waves within the millimeter wave and terahertz regimes, polar gaseous molecules generate unique rotational spectra. The frequency and absorption intensity of rotational spectral lines ...
Design methods for sensitive and comprehensive microbial surveillance
(Massachusetts Institute of Technology, 2020)
We are surrounded by a vast and dynamic microbial world. Effective surveillance tools can benefit medicine and public health, including infectious disease diagnostics, proactive pathogen detection and characterization, and ...
Integrated optical phased arrays for three-dimensional display applications
(Massachusetts Institute of Technology, 2020)
The compatibility of silicon photonic platforms with complementary metal-oxide-semiconductor (CMOS) fabrication processes has facilitated a surge in the development of silicon-based integrated optical phased arrays (OPAs) ...
