FORTAP: Using Formulas for Numerical-Reasoning-Aware Table Pretraining
Zhoujun Cheng, Haoyu Dong, Ran Jia +4
Tables store rich numerical data, but numerical reasoning over tables is still a challenge. In this paper, we find that the spreadsheet formula, which performs calculations on nume…
A Numerical Study on the Wiretap Network with a Simple Network Topology
Fan Cheng, Vincent Y. F. Tan
In this paper, we study a security problem on a simple wiretap network, consisting of a source node S, a destination node D, and an intermediate node R. The intermediate node conne…
Generalization of Mrs. Gerber's Lemma
Fan Cheng
Mrs. Gerber's Lemma (MGL) hinges on the convexity of , where is the binary entropy function. In this work, we prove that is convex in for eve…
Higher Order Derivatives in Costa's Entropy Power Inequality
Fan Cheng, Yanlin Geng
Let be an arbitrary continuous random variable and be an independent Gaussian random variable with zero mean and unit variance. For , Costa proved that $e^{2h(X+\sqr…
Performance Bounds on a Wiretap Network with Arbitrary Wiretap Sets
Fan Cheng, Raymond W. Yeung
Consider a communication network represented by a directed graph , where is the set of nodes and is the set of po…
Imperfect Secrecy in Wiretap Channel II
Fan Cheng, Raymond W. Yeung, Kenneth W. Shum
In a point-to-point communication system which consists of a sender, a receiver and a set of noiseless channels, the sender wishes to transmit a private message to the receiver thr…
