Mining Frequent Patterns in Uncertain and Relational Data Streams using the Landmark Windows

fatemeh Abdi; Aliasghar Safaei

Volume 1, Issue 4 , November 2015, , Pages 43-52

Abstract
  Todays, in many modern applications, we search for frequent and repeating patterns in the analyzed data sets. In this search, we look for patterns that frequently appear in data set and mark them as frequent patterns to enable users to make decisions based on these discoveries. Most algorithms presented ...  Read More

Online multiple people tracking-by-detection in crowded scenes

Sahar Rahmatian; Reza Safabakhsh

Volume 1, Issue 2 , May 2015, , Pages 15-22

Abstract
  Multiple people detection and tracking is a challenging task in real-world crowded scenes. In this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. We have detected objects with deformable part models and a visual background extractor. In the tracking ...  Read More

Adaptive Rule-Base Influence Function Mechanism for Cultural Algorithm

Vahid Seydi Ghomsheh; Mohamad Teshnehlab; Mehdi Aliyari Shoordeli

Volume 1, Issue 2 , May 2015, , Pages 29-38

Abstract
  This study proposes a modified version of cultural algorithms (CAs) which benefits from rule-based system for influence function. This rule-based system selects and applies the suitable knowledge source according to the distribution of the solutions. This is important to use appropriate influence function ...  Read More
