Home and destination attachment: study of cultural integration on Twitter

no code implementations22 Feb 2021 Jisu Kim, Alina Sîrbu, Giulio Rossetti, Fosca Giannotti, Hillel Rapoport

In particular, the common language between home and destination countries corresponds to increased home attachment, as does low proficiency in the host language.

Restore from Restored: Single-image Inpainting

no code implementations16 Feb 2021 Eunhye Lee, Jeongmu Kim, Jisu Kim, Tae Hyun Kim

Recent image inpainting methods show promising results due to the power of deep learning, which can explore external information available from a large training dataset.

Vector meson mass in the chiral symmetry restored vacuum

no code implementations11 Dec 2020 Jisu Kim, Su Houng Lee

By taking the chiral symmetry breaking part to be zero while keeping the symmetric operator to the vacuum value, we find that the chiral symmetric part of the vector and axial vector meson mass to be between 550 and 600 MeV.

PLLay: Efficient Topological Layer based on Persistent Landscapes

1 code implementation NeurIPS 2020 Kwangho Kim, Jisu Kim, Manzil Zaheer, Joon Kim, Frederic Chazal, Larry Wasserman

We propose PLLay, a novel topological layer for general deep learning models based on persistence landscapes, in which we can efficiently exploit the underlying topological features of the input data structure.

Generalized Penalty for Circular Coordinate Representation

1 code implementation3 Jun 2020 Hengrui Luo, Alice Patania, Jisu Kim, Mikael Vejdemo-Johansson

We provide simulation experiments and real data analysis to support our claim that circular coordinates with generalized penalty will detect the change in high-dimensional datasets under different sampling schemes while preserving the topological structures.

Statistical Inference for Cluster Trees

no code implementations NeurIPS 2016 Jisu Kim, Yen-Chi Chen, Sivaraman Balakrishnan, Alessandro Rinaldo, Larry Wasserman

A cluster tree provides a highly-interpretable summary of a density function by representing the hierarchy of its high-density clusters.

Introduction to the R package TDA

2 code implementations7 Nov 2014 Brittany Terese Fasy, Jisu Kim, Fabrizio Lecci, Clément Maria

The salient topological features of the sublevel sets (or superlevel sets) of these functions can be quantified with persistent homology.
