Modeling Output-Level Task Relatedness in Multi-Task Learning with Feedback Mechanism

no code implementations1 Apr 2024 Xiangming Xi, Feng Gao, Jun Xu, Fangtai Guo, Tianlei Jin

Multi-task learning (MTL) is a paradigm that simultaneously learns multiple tasks by sharing information at different levels, enhancing the performance of each individual task.

Sparsity via Sparse Group $k$-max Regularization

no code implementations13 Feb 2024 Qinghua Tao, Xiangming Xi, Jun Xu, Johan A. K. Suykens

For the linear inverse problem with sparsity constraints, the $l_0$ regularized problem is NP-hard, and existing approaches either utilize greedy algorithms to find almost-optimal solutions or to approximate the $l_0$ regularization with its convex counterparts.

Fast Contextual Scene Graph Generation With Unbiased Context Augmentation

no code implementations CVPR 2023 Tianlei Jin, Fangtai Guo, Qiwei Meng, Shiqiang Zhu, Xiangming Xi, Wen Wang, Zonghao Mu, Wei Song

Therefore, at the context level, we can produce diverse context descriptions by using a context augmentation method based on the original dataset.

Piecewise Linear Neural Networks and Deep Learning

no code implementations18 Jun 2022 Qinghua Tao, Li Li, Xiaolin Huang, Xiangming Xi, Shuning Wang, Johan A. K. Suykens

To apply PWLNN methods, both the representation and the learning have long been studied.

Efficient hinging hyperplanes neural network and its application in nonlinear system identification

no code implementations15 May 2019 Jun Xu, Qinghua Tao, Zhen Li, Xiangming Xi, Johan A. K. Suykens, Shuning Wang

It is proved that for every EHH neural network, there is an equivalent adaptive hinging hyperplanes (AHH) tree, which was also proposed based on the model of HH and find good applications in system identification.
