MPC Protocol for G-module and its Application in Secure Compare and ReLU

Qizhi Zhang, Lichun Li, Shan Yin +1

Secure comparison and secure selection are two fundamental MPC (secure Multi-Party Computation) protocols. One important application of these protocols is the secure ReLU and DReLU…

Matrix embedding method in match for session-based recommendation

Qizhi Zhang, Yi Lin, Kangle Wu +2

Session based model is widely used in recommend system. It use the user click sequence as input of a Recurrent Neural Network (RNN), and get the output of the RNN network as the ve…

Category coding with neural network application

Qizhi Zhang, Kuang-chih Lee, Hongying Bao +2

In many applications of neural network, it is common to introduce huge amounts of input categorical features, as well as output labels. However, since the required network size sho…

An Improvement to the Number Field Sieve

Qizhi Zhang

We improve the "sieve" part of the number field sieve used in factoring integer and computing discrete logarithm. The runtime of our method is shorter than that of existing methods…

On the ramification of non-abelian Galois coverings of degree

Qizhi Zhang

The refined Swan conductor is defined by K.\ Kato \cite{KK2}, and generalized by T.\ Saito \cite{wild}. In this part, we consider some smooth -adic étale sheaves of rank suc…
