On the Spectrum of the Line Graph of a Family of Bipartite Graphs Arising from the Boolean Lattice

Ali Zafari, Saeid Alikhani

The Boolean lattice $B L_{n}$ , $n \geq 3$ , is the graph whose vertex set is the collection of all subsets of $[n] = {1, 2, \dots, n}$ , where two subsets $U$ and $W$ are adjacent if and o…

The partition dimension and $k$ -domination number of a family of non-distance regular graph

Ali Zafari, Saeid Alikhani

A partition $Σ = {S_{1}, S_{2}, \dots, S_{k}}$ of the vertex set $V (G)$ is a resolving partition if every pair of distinct vertices in $G$ has a unique representation relative to $Σ$ . T…

Some results on Hamming graphs and an extended Hamming graphs

Ali Zafari, Saeid Alikhani

In this paper we first obtain the spectrum of the folded hypercube in a new approach. Then we introduce a new family of graphs called the extended Hamming graph, denoted by $EH(n,2…

Frequency Disentangled Features in Neural Image Compression

Ali Zafari, Atefeh Khoshkhahtinat, Piyush Mehta +3

The design of a neural image compression network is governed by how well the entropy model matches the true distribution of the latent code. Apart from the model capacity, this abi…

A Quality Aware Sample-to-Sample Comparison for Face Recognition

Mohammad Saeed Ebrahimi Saadabadi, Sahar Rahimi Malakshan, Ali Zafari +2

Currently available face datasets mainly consist of a large number of high-quality and a small number of low-quality samples. As a result, a Face Recognition (FR) network fails to…

Metric dimension, doubly resolving set and strong metric dimension for $(C_{n} □ P_{k}) □ P_{m}$

Jia-Bao Liu, Ali Zafari

A subset $Q = {q_{1}, q_{2}, ..., q_{l}}$ of vertices of a connected graph $G$ is a doubly resolving set of $G$ if for any various vertices $x, y \in V (G)$ we have $r(x|Q)-r(y|Q)\neqλI…

Some resolving parameters with the minimum size for two specific graphs

Ali Zafari, Saeid Alikhani

A resolving set for a graph $G$ is a set of vertices $Q = {q_{1}, ..., q_{k}}$ such that, for all $p \in V (G)$ the $k$ -tuple $(d (p, q_{1}), ..., d (p, q_{k}))$ uniquely determines $p$ , wh…

Some algebraic properties of a class of integral graphs determined by their spectrum

Jia-Bao Liu, S. Morteza Mirafzal, Ali Zafari

Let $Γ = (V, E)$ be a graph. If all the eigenvalues of the adjacency matrix of the graph $Γ$ are integers, then we say that $Γ$ is an integral graph. A graph $Γ$ is determined by its…
