Lower Bounds on Conversion Bandwidth for MDS Convertible Codes in Split Regime

Lewen Wang, Sihuang Hu

We propose several new lower bounds on the bandwidth costs of MDS convertible codes using a linear-algebraic framework. The derived bounds improve previous results in certain param…

Lower Bounds on the Sub-Packetization of Optimal-Access MSR Codes for Multiple-Node Repair

Lewen Wang, Zihao Zhang, Sihuang Hu

We establish lower bounds on the sub-packetization of optimal-access MSR codes in the context of multiple-node failures. These bounds generalize the tight bounds for single-node fa…

BPQP: A Differentiable Convex Optimization Framework for Efficient End-to-End Learning

Jianming Pan, Zeqi Ye, Xiao Yang +4

Data-driven decision-making processes increasingly utilize end-to-end learnable deep neural networks to render final decisions. Sometimes, the output of the forward functions in ce…
