Debris Of Progress: A Political Ethnography Of Critical Infrastructure, Ethan Tupelo
Debris Of Progress: A Political Ethnography Of Critical Infrastructure, Ethan Tupelo
Doctoral Dissertations
In this dissertation, I advance a political ethnography of critical infrastructure to better understand terminal capitalism, in which the waste products of commodification and resource depletion are destroying the ecological systems that support life. My object of study is the massive disjuncture between individual knowledge and intention, and these catastrophic collective planetary outcomes. Theoretically, I develop critical infrastructure theory to diagnose these destructive structures. By “infrastructure,” I mean systems of material and discursive flows fundamental to sedentary human organization, connecting local actions with global systems. Such infrastructure is “critical” in three senses: A) denoting the most important forms of infrastructure …
Sparse Model Selection Using Information Complexity, Yaojin Sun
Sparse Model Selection Using Information Complexity, Yaojin Sun
Doctoral Dissertations
This dissertation studies and uses the application of information complexity to statistical model selection through three different projects. Specifically, we design statistical models that incorporate sparsity features to make the models more explanatory and computationally efficient.
In the first project, we propose a Sparse Bridge Regression model for variable selection when the number of variables is much greater than the number of observations if model misspecification occurs. The model is demonstrated to have excellent explanatory power in high-dimensional data analysis through numerical simulations and real-world data analysis.
The second project proposes a novel hybrid modeling method that utilizes a mixture …
