On Differentially Private Stochastic Convex Optimization with Heavy-tailed Data
Di Wang, Hanshen Xiao, Srini Devadas +1
In this paper, we consider the problem of designing Differentially Private (DP) algorithms for Stochastic Convex Optimization (SCO) on heavy-tailed data. The irregularity of such d…
Detecting anomalous citation groups in journal networks
Sadamori Kojaku, Giacomo Livan, Naoki Masuda
The ever-increasing competitiveness in the academic publishing market incentivizes journal editors to pursue higher impact factors. This translates into journals becoming more sele…
Embedding Cosmology and Gravity
Abhishek Goswami
I start with a scenario where the universe is an abstract space having dimensions. There is a two dimensional surface embedded in it. Embedding is a map from the…
Comparison of Split-Step and Hamiltonian Integration Methods for Simulation of the Nonlinear Schrödinger Equation
Anastassiya Semenova, Sergey A. Dyachenko, Alexander O. Korotkevich +1
We provide a systematic comparison of two numerical methods to solve the widely used nonlinear Schrödinger equation. The first one is the standard second order split-step (SS2) met…
Crystal and Magnetic Structure of Polar Oxide HoCrWO
C. Dhital, D. Pham, T. Lawal +6
Polar magnetic oxide HoCrWO is synthesized and its crystal structure, magnetic structure, and thermodynamic properties are investigated. HoCrWO forms the polar crystal stru…
Road Grade Estimation Using Crowd-Sourced Smartphone Data
Abhishek Gupta, Shaohan Hu, Weida Zhong +3
Estimates of road grade/slope can add another dimension of information to existing 2D digital road maps. Integration of road grade information will widen the scope of digital map's…
