Linear mappings of local preserving-majorization on matrix algebrasJan 09 2013Jan 10 2013Let $\M_{n\times n}$ be the algebra of all $n\times n$ matrices. For $x,y\in {R}^{n}$ it is said that $x$ is majorized by $y$ if there is a double stochastic matrix $A\in {M}_{n\times n}$ such that $x=Ay$ (denoted by $x\prec y$). Suppose that $\Phi$ is ... More
Transferable Natural Language Interface to Structured Queries aided by Adversarial GenerationDec 04 2018Dec 07 2018A natural language interface (NLI) to structured query is intriguing due to its wide industrial applications and high economical values. In this work, we tackle the problem of domain adaptation for NLI with limited data on target domain. Two important ... More
