Capacity Region of the Broadcast Channel with Two Deterministic Channel State Components

This paper establishes the capacity region of a class of broadcast channels with random state in which each channel component is selected from two possible functions and each receiver knows its state sequence. This channel model does not fit into any class of broadcast channels for which the capacity region was previously known and is useful in studying wireless communication channels when the fading state is known only at the receivers. The capacity region is shown to coincide with the UV outer bound and is achieved via Marton coding.Comment: 5 pages, 3 figures. Submitted to ISIT 201

History's "Me Too" Movement: Recognizing the Political Agency of Korean "Comfort Women"

This paper seeks to answer a few questions. Within the context of how justice is delivered in post-conflict settings, in what ways are women’s agency limited? In other words, why is a gendered lens to agency needed? Additionally, how have the South Korean "comfort women" exercised their agency in the political space, and what lessons do they leave behind? The next section delves more specifically into ways that tools of transitional justice have reproduced the silence and invisibility that women experience in pre-conflict and conflict situations. Building off criticisms of transitional justice mechanisms, the paper suggests what a gendered lens to agency may look like, building upon the theories laid out by Björkdahl and Selimovic in their 2015 article "Gendering Agency in Transitional Justice." The consequent section will apply this gendered lens of agency to the case of the South Korean "comfort women," looking at details of how the survivors have exercised agency in their campaign for justice. Here, the central concern of the theorization of a gendered lens to agency or the case examination is not on institutional or policy changes that result from their campaign and activism; even if there is an institutional change or a policy concession, we may not necessarily see women's experiences, their political requests, and needs being fully reflected and incorporated. The ends is not the measure of success; rather, it is the voice that women have articulated and the steps that they have taken that expands our understanding of politics and agency.No embargoAcademic Major: EconomicsAcademic Major: Political Scienc

Discovering Potential Correlations via Hypercontractivity

Discovering a correlation from one variable to another variable is of fundamental scientific and practical interest. While existing correlation measures are suitable for discovering average correlation, they fail to discover hidden or potential correlations. To bridge this gap, (i) we postulate a set of natural axioms that we expect a measure of potential correlation to satisfy; (ii) we show that the rate of information bottleneck, i.e., the hypercontractivity coefficient, satisfies all the proposed axioms; (iii) we provide a novel estimator to estimate the hypercontractivity coefficient from samples; and (iv) we provide numerical experiments demonstrating that this proposed estimator discovers potential correlations among various indicators of WHO datasets, is robust in discovering gene interactions from gene expression time series data, and is statistically more powerful than the estimators for other correlation measures in binary hypothesis testing of canonical examples of potential correlations.Comment: 30 pages, 19 figures, accepted for publication in the 31st Conference on Neural Information Processing Systems (NIPS 2017
