A design methodology for computer architecture parameterized by robot morphology
(Massachusetts Institute of Technology, 2020)
Robots that safely interact with people are a promising solution to address societal challenges from elder care to hazardous work environments. A key computational barrier to the robust autonomous operation of complex ...
Interactive data analytics using GPUs
(Massachusetts Institute of Technology, 2020)
Modern GPUs provide an order-of-magnitude greater memory bandwidth compared to CPUs. In theory, this means data processing systems can process O(TB) of data with sub 100ms latency, thereby enabling interactive query response ...
New hardness results for total search problems and non-interactive lattice-based protocols
(Massachusetts Institute of Technology, 2020)
We investigate new hardness results for total search problems, namely search problems that always have a solution, and non-interactive lattice protocols. 1. A question of particular importance, raised together with the ...
Efficient metric representations for big data
(Massachusetts Institute of Technology, 2020)
Contemporary datasets are often represented as points in a high-dimensional metric space. To deal with increasingly larger datasets, many algorithms rely on efficient or compressed representations of the induced metric. ...
Evaluating robustness of neural networks
(Massachusetts Institute of Technology, 2020)
The robustness of neural networks to adversarial examples has received great attention due to security implications. Despite various attack approaches to crafting visually imperceptible adversarial examples, little has ...
Analysis and optimization of occluder-based imaging
(Massachusetts Institute of Technology, 2020)
Occluders, i.e. opaque objects, can be used in the apertures of cameras to supplement or replace a traditional lens. This thesis describes a novel mutual information-theoretic framework for analyzing and comparing occluders. ...
New frontiers in THz quantum cascade lasers
(Massachusetts Institute of Technology, 2020)
Terahertz (THz) frequencies (0.5-10 THz) are among the most underdeveloped electromagnetic spectra, even though their application potentials are great in imaging, sensing, and communications. This underdevelopment is ...
Dynamically programmable surfaces for high-speed optical modulation and detection
(Massachusetts Institute of Technology, 2020)
Dynamically programmable surfaces for spatiotemporal control of light are crucial to many optoelectronic technologies including high-speed optical communication, display and projection, autonomous driving, optical information ...
Hardware-aware efficient deep neural network design
(Massachusetts Institute of Technology, 2020)
Deep neural networks (DNNs) deliver best-in-class accuracy on various artificial intelligence applications. However, the high accuracy comes at the cost that the computational complexity of DNNs is much higher than that ...
