In the era of digital information, the size of data collection has been growing significantly. Knowledge results in term of association rules obtained from the set of data are numerous and hard to select. This paper proposes the approach for selecting the interesting subsets of association rules from big association results. The selective criterion is based on well-known interesting measures including...
Highway no.7 is the main route for transportation between Bangkok to the eastern seaboard. The eastern seaboard is the major economic region of Thailand. This paper applies theory of rough set to find the hidden relationship among date, time, entering station, exit station and vehicular traffic. The transactional data was gathered from the Division of Inter City Motorway, Department of Highways in...
The stock index indicators, e.g., Moving Average (MA), Relative Strength Index (RSI), Price Rate of Change (PROC), Moving Average Convergence Divergence (MACD), or Stochastic Oscillator (STH) are often used as the main factor in trading. Stock traders decide to trade by using these indicators. This paper applies theory of rough set to find the hidden relationship among these indicators which affects...
Routing and wavelength assignment (RWA) is a well-known issue in wavelength division multiplexing (WDM) optical networks. In this paper, we present RWA design for WDM networks by considering multiple design objectives which are maximizing the number of traffic demands to be served and minimizing the number of wavelength channels to be assigned. A hybrid evolutionary computation approach consisting...
In this paper, we develop a multi-objective network design model for the traffic grooming, routing and wavelength assignment (GRWA) in WDM networks. We consider and evaluate four traffic grooming strategies which are Point to Point (P2P), Point to Multi-Point (P2MP), Multi-Point to Point (MP2P) and Multi-Point to Multi-Point (MP2MP). The design objectives are to maximize the number of accepted communication...
