skscope: Fast Sparsity-Constrained Optimization in Python

1 code implementation27 Mar 2024 Zezhi Wang, Jin Zhu, Peng Chen, Huiyang Peng, Xiaoke Zhang, Anran Wang, Yu Zheng, Junxian Zhu, Xueqin Wang

Applying iterative solvers on sparsity-constrained optimization (SCO) requires tedious mathematical deduction and careful programming/debugging that hinders these solvers' broad impact.

A Consistent and Scalable Algorithm for Best Subset Selection in Single Index Models

no code implementations12 Sep 2023 Borui Tang, Jin Zhu, Junxian Zhu, Xueqin Wang, Heping Zhang

SIMs provide an interpretable and flexible modeling framework for high-dimensional data, while best subset selection aims to find a sparse model from a large set of predictors.

Interpreting and predicting the economy flows: A time-varying parameter global vector autoregressive integrated the machine learning model

no code implementations31 Jul 2022 Yukang Jiang, Xueqin Wang, Zhixi Xiong, Haisheng Yang, Ting Tian

The paper proposes a time-varying parameter global vector autoregressive (TVP-GVAR) framework for predicting and analysing developed region economic variables.

The impact of spatio-temporal travel distance on epidemics using an interpretable attention-based sequence-to-sequence model

no code implementations26 May 2022 Yukang Jiang, Ting Tian, Huajun Xie, Hailiang Guo, Xueqin Wang

We unveil the geographical variations in the influence of population movement at different travel distances on the dynamics of epidemic spread.

A Splicing Approach to Best Subset of Groups Selection

1 code implementation23 Apr 2021 Yanhang Zhang, Junxian Zhu, Jin Zhu, Xueqin Wang

Best subset of groups selection (BSGS) is the process of selecting a small part of non-overlapping groups to achieve the best interpretability on the response variable.

Ball: An R package for detecting distribution difference and association in metric spaces

1 code implementation9 Nov 2018 Jin Zhu, Wenliang Pan, Wei Zheng, Xueqin Wang

The rapid development of modern technology facilitates the appearance of numerous unprecedented complex data which do not satisfy the axioms of Euclidean geometry, while most of the statistical hypothesis tests are available in Euclidean or Hilbert spaces.
