Two-Cut Coherence of Quintic Forms: Lifting Separations and Second-Derivative Completeness
Karthik Sheshadri
For a homogeneous polynomial f of degree d, the degree-k restricted strength C_k(f) is the least number of products needed to write f with factor degrees k and d-k. We introduce a…
Trellis State Complexity as an Exact Tropical Factorization Rank
Karthik Sheshadri
Let $C\subseteq\F_2^m$ be a binary linear code and let be a bipartition of its coordinates. The \emph{conditional decoding matrix} of at this cut is the matrix…
Contested Cluster Selectors: Local Ambiguity, Normal Forms, and Backtracking Cost in Random Constraint Satisfaction
Karthik Sheshadri
We introduce and empirically investigate \emph{contested cluster selectors} (\CCS): variables that are non-backbone, carry information about solution-cluster identity, and are repe…
Conormal Lower Bounds for Determinantal Complexity: Fermat Slices, Tight Bounds, and a Ceiling
Karthik Sheshadri
The determinantal complexity of a polynomial is the smallest size of a matrix of affine linear forms whose determinant is ; the border version only asks for determinants con…
A fully Lean-verified quadratic lower bound on the border determinantal complexity of over , including the symmetric and exact models
Karthik Sheshadri
We present the first end-to-end Lean-verified superlinear lower bound on border determinantal complexity. Let . We prove, over , that the border…
A short proof of a quadratic lower bound on the border determinantal complexity of over : A simple human exposition
Karthik Sheshadri
I give a short proof that the border determinantal complexity of over is at least , and at least in the symmetric…
Building a Benchmark Dataset and Classifiers for Sentence-Level Findings in AP Chest X-rays
Tanveer Syeda-Mahmood, Hassan M. Ahmad, Nadeem Ansari +9
Chest X-rays are the most common diagnostic exams in emergency rooms and hospitals. There has been a surge of work on automatic interpretation of chest X-rays using deep learning a…
The Causal Link between News Framing and Legislation
Karthik Sheshadri, Chung-Wei Hang, Munindar Singh
We demonstrate that framing, a subjective aspect of news, is a causal precursor to both significant public perception changes, and to federal legislation. We posit, counter-intuiti…
Framing Matters: Predicting Framing Changes and Legislation from Topic News Patterns
Karthik Sheshadri, Chung-Wei Hang, Munindar Singh
News has traditionally been well researched, with studies ranging from sentiment analysis to event detection and topic tracking. We extend the focus to two surprisingly under-resea…
