Berlekamp and Zigangirov completely determined the capacity error function for binary error correcting codes with noiseless feedback. It is still an unsolved problem if the upper bound for the capacity error function in the non-binary case of Ahlswed

Graph covers and the Bethe free energy have been useful theoretical tools for producing lower bounds on a variety of counting problems in graphical models, including the permanent and the ferromagnetic Ising model. Here, we propose a new conjecture t

Zero correlation zone (ZCZ) sequence sets play an important role in interference-free quasi-synchronous code-division multiple access communications. In this paper, for the first time, we investigate the periodic correlation properties of polyphase s

Generative models for networks with communities have been studied extensively for being a fertile ground to establish information-theoretic and computational thresholds. In this paper we propose a new toy model for planted generative models called pl

In this paper, we investigate the convergence rate of k Nearest Neighbor (kNN) regression methods. We first derive the minimax bound for nonparametric regression under some general tail and smoothness assumptions. This bound shows that, when the dist

We study the performance of noisy gradient descent and Nesterov's accelerated methods for strongly convex objective functions with Lipschitz continuous gradients. The steady-state second-order moment of the error in the iterates is analyzed when the

We consider the task of tensor estimation, i.e. estimating a low-rank 3-order $n \times n \times n$ tensor from noisy observations of randomly chosen entries in the sparse regime. In the context of matrix (2-order tensor) estimation, a variety of alg

The positive classical solutions of nonlinear reaction diffusion equations is given under nonlinear boundary flux in bounded domain. By constructing auxiliary functions and applying the maximum principle, the sufficient conditions for the existence o

The inverse Weibull distribution has the ability to model failure rates which are quite common in reliability studies. In this paper, the three-parameter generalized inverse Weibull distribution for electrical components reliability analysis is studi

The deployment of massive MIMO systems has revived much of the interest in the study of the large-system performance of multiuser detection systems. In this paper, we prove a non-trivial upper bound on the bit-error rate (BER) of the MAP detector for
