چکیده

This paper presents techniques to integrate boundary overlap into concept assignment using Plausible Reasoning. Heuristic search techniques such as Hill climbing and Genetic Algorithms are investigated. A new fitness measure appropriate for overlapping concept assignment is introduced. The new algorithms are compared to randomly generated results and the Genetic Algorithm is shown to be the best of the proposed search algorithms in terms of the quality of concept binding, as measured by the fitness function. The fixed boundary Hypothesis Based Concept Assignment technique is compared to the new algorithms. The Genetic Algorithm and Hill climbing are found to consistently produce stronger concepts than Hypothesis Based Concept Assignment.

FUZZY GRAVITATIONAL SEARCH ALGORITHM AN APPROACH FOR DATA MINING

The concept of intelligently controlling the search process of gravitational search algorithm (GSA) is introduced to develop a novel data mining technique. The proposed method is called fuzzy GSA miner (FGSA-miner). At first a fuzzy controller is designed for adaptively controlling the gravitational coefficient and the number of effective objects, as two important parameters which play major ro...

OPTIMAL DESIGN OF STEEL MOMENT FRAME STRUCTURES USING THE GA-BASED REDUCED SEARCH SPACE (GA-RSS) TECHNIQUE

This paper proposes a GA-based reduced search space technique (GA-RSS) for the optimal design of steel moment frames. It tries to reduce the computation time by focusing the search around the boundaries of the constraints, using a ranking-based constraint handling to enhance the efficiency of the algorithm. This attempt to reduce the search space is due to the fact that in most optimization pro...

A Sociological Study of the Effects of Lifestyle on Social Identity and its Effective Factors

The line between lifestyle and social identity in sociology is based on the distinction between traditional and modern society. In traditional societies lifestyle and social identity are based on their related features. However, in this regard, in terms of time precedence, modern societies mainly offer two different answers, each based on different theoretical approaches. The first and the olde...

A Novel Ensemble Approach for Anomaly Detection in Wireless Sensor Networks Using Time-overlapped Sliding Windows

One of the most important issues concerning the sensor data in the Wireless Sensor Networks (WSNs) is the unexpected data which are acquired from the sensors. Today, there are numerous approaches for detecting anomalies in the WSNs, most of which are based on machine learning methods. In this research, we present a heuristic method based on the concept of “ensemble of classifiers” of data minin...
