Currency exchange rates forecasting is paid a considerable attention of the researchers in the field of forecasting. The neural network is a well-known tool in machine learning. However, two issues are always interested by the scientists: getting toward to global convergence of extreme solutions and determining the optimal weight of the network. This paper proposes the multi-objective method of ensemble...
Time Series Forecasting is an area being concerned by the researchers. Recently, many time series forecasting solutions have been given, but the forecasting accuracy of these solutions needs to be taken into consideration. In this paper, we propose an evolutionary ensemble-based model and experimented it on four sets of test data on exchange rates (USD, NZD, USD and YEN) against the AUD. We applied...
A novel technique for obtaining the correlation of spectrally encoded information is presented. The information encoded in the spectrum of ultrafast optical pulses is mapped into time domain using dispersion and is then mixed with a spectrally engineered broadband pump using four wave mixing to create a narrow band idler. This idler could then be filtered and integrated using electronics. Unlike previous...
A novel instantaneous frequency measurement using all optical mixing is demonstrated. This system can provide RF frequency measurement while requiring no high speed electronic components and remoting all components of the measurement system to the receiver.
This paper proposes a framework, that incorporates evolutionary computation and wargame simulation, to investigate the role of information networks in organizing efficient supply chains for military logistics. Under the proposed framework, evolutionary computation is used to evolve the information networks, which are subsequently evaluated by playing simulation wargames. Through a series of simulation...
A simple technique to improve the sensitivity of a photonic instantaneous frequency measurement receiver using low-cost, low-frequency photo-detectors is proposed and practically demonstrated. The introduction of the lock-in amplification allows RF input power can be reduced by 16 dB when compared to the un-locked system while still maintaining sensitivity. Formal quantification of the noise floor...
Projector-camera system has been researched for years and it has become more and more popular in 3D vision and many other applications. However, with pre-determined position of projector's lens, projector based researches were not able to deal with the scenes that have objects with different distances from the projector. In this paper, we present a projector autofocusing technique based on local blur...
In this paper we propose and demonstrate a photonically implemented instantaneous frequency measurement system. This system uses two differentially delayed modulated optical carriers that are mixed using a semiconductor optical amplifier. The output of the system includes a DC component that varies as a function of frequency. This can be used for frequency measurement using a low-cost DC photo-detector...
