Improved weight initialization for deep and narrow feedforward neural network

no code implementations7 Nov 2023 Hyunwoo Lee, Yunho Kim, Seung Yeop Yang, Hayoung Choi

The problem of \textquotedblleft dying ReLU," where ReLU neurons become inactive and yield zero output, presents a significant challenge in the training of deep neural networks with ReLU activation function.

Algorithm Unrolling for Massive Access via Deep Neural Network with Theoretical Guarantee

no code implementations19 Jun 2021 Yandong Shi, Hayoung Choi, Yuanming Shi, Yong Zhou

Moreover, the proposed algorithm unrolling approach inherits the structure and domain knowledge of the ISTA, thereby maintaining the algorithm robustness, which can handle non-Gaussian preamble sequence matrix in massive access.

An algebraic-geometric approach for linear regression without correspondences

no code implementations12 Oct 2018 Manolis C. Tsakiris, Liangzu Peng, Aldo Conca, Laurent Kneip, Yuanming Shi, Hayoung Choi

This naturally leads to a polynomial system of $n$ equations in $n$ unknowns, which contains $\xi^*$ in its root locus.
