Linear algebra on lattices : Simit language extensions with applications to lattice QCD
(Massachusetts Institute of Technology, 2016)
This thesis presents language extensions to Simit, a language for linear algebra on graphs. Currently, Simit doesn't efficiently handle lattice graphs (regular grids). This thesis defines a stencil assembly construct to ...
Online neuron reconstruction
(Massachusetts Institute of Technology, 2016)
In this thesis, I designed an algorithm that traces neurons through the images of various datasets extracted from mouse brains. The algorithm is implemented in Python and relies on the output of a recently developed Fully ...
Tracking eye behavior in decision-making maze problems
(Massachusetts Institute of Technology, 2019)
Neurodegenerative diseases, such as Alzheimer's and Huntington's, can significantly impact a patient's ability to solve everyday problems. The ability to detect early signs of mental decline is crucial for determining ...
Interactive exploration of design space
(Massachusetts Institute of Technology, 2019)
Typical design for manufacturing applications requires simultaneous optimization of conflicting performance objectives: Design variations that improve one performance metric may decrease another performance metric. In these ...
Message passing neural networks for molecular property prediction
(Massachusetts Institute of Technology, 2019)
Developing new drugs relies heavily on understanding the various molecular properties of potential drug candidates. While experimental assays performed in the lab are the best source of information about molecular properties, ...
Joint generation of image and text with GANs
(Massachusetts Institute of Technology, 2019)
The computer vision and natural language processing communities have come together on image captioning related problems, but the fields have remained largely disjoint. There has been work in transforming text to text, ...
Detecting check-worthy claims
(Massachusetts Institute of Technology, 2019)
An automated fact-checking system aims to check the factuality of published information, such as news articles or blog posts. It is a time-consuming process and contains several steps: (i ) detecting check-worthy claims, ...
Python Semantic Investigator : an interactive debugger with reversible state
(Massachusetts Institute of Technology, 2019)
This thesis describes PSI (Python Semantic Investigator), a program designed to help students explore their code by allowing them to see the state of their program at any step along its execution. PSI enables them to move ...
New methods for approximating shortest paths
(Massachusetts Institute of Technology, 2019)
A spanner H of a graph G is a sparse subgraph that approximates all pairwise distances. Of particular interest are additive spanners on unweighted graphs, which satisfy the following for and two vertices u, v. dist(H, u, ...
High performance data processing pipeline for connectome segmentation
(Massachusetts Institute of Technology, 2016)
By investigating neural connections, neuroscientists try to understand the brain and reconstruct its connectome. Automated connectome reconstruction from high resolution electron miscroscopy is a challenging problem, as ...
