Hierarchical Clustering of Complex Symbolic Data and Application for Emitter Identification

Journal of computer Science & technology 2018年第4期33卷 807-822页

It is well-known that the values of symbolic variables may take various forms such as an interval, a set of stochastic measurements of some underlying patterns or qualitative multi-values and so on. However, the majority of existing work in symbolic data analysis still focuses on interval values. Although some pioneering work in stochastic pattern based symbolic data and mixture of symbolic variables has been explored, it still lacks flexibility and computation efficiency to make full use of the distinctive individual symbolic variables. Therefore, we bring forward a novel hierarchical clustering method with weighted general Jaccard distance and effective global pruning strategy for complex symbolic data and apply it to emitter identification. Extensive experiments indicate that our method has outperformed its peers in both computational efficiency and emitter identification accuracy.

Along with the electrification, there are many electrical equipment are used in our daily life. Using those equipment we need cables to charge and connect them. But, sometimes cables will become problems, like when we clean the room the cables will be annoying. We think if we can resolve this problem with robot, it will save lots of time for people. But, unfortunately, there is no system which can manipulate cables with robot. The key point is cable can deform it's shape. Because of this, we can't recognize and record cables position correctly from picture. And if we want to manipulate cables with robot, the 3D information of cables is far batter than 2D information. Therefore, in this paper, we made a system which can build a 3D voxels model base on 2D image as a beforehand for use robot to manipulate cables. In our system, we cut input image into a series of small pictures and make 3D model based on each pictures then we assemble those 3D model together. So we can get a complete 3D model(output of this system) which is made base on input image and can represent the 3D cables position. Our method can transfer 2D data to 3D data, this let us can get 3D information from image and we think this is useful in robot science. © 2021 IEEE.

Agriculture planning plays a dominant role in the economic growth and food security of agriculture-based countries such as Sri Lanka. Even though agriculture plays a vital role, there are still several major complications to be addressed. Some of the major complications are lack of knowledge about yield and price resulting in the farmers selecting crops based on experience. Machine learning has a great potential to solve these complications. To this end, this paper proposes a novel system comprises of a mobile application, SMS (Short Message Service), and API (Application Programming Interface) with yield prediction, price prediction, and crop optimization. Several machine learning algorithms were used for yield and price predictions while a generic algorithm was used to optimize crops. The yield was predicted considering the environmental factors while the price was predicted considering supply and demand, import and export, and seasonal effect. To select the best suitable crops to cultivate, the output of yield and price prediction have been used. Yield prediction has been implemented using elastic net, ridge, and multilinear regression. R2 of yield prediction is varied from 0.74 to 0.89 while RMSE value is between 15.69 and 35.05. Price prediction has been implemented using the algorithms of Gradient Boosting Tree, Random Forest, Facebook Prophet, and R2 is varied from 0.72 to 0.92 while RMSE value is between 26.81 and 140.72. Crop optimization has been implemented using the genetic algorithm. © 2021 IEEE.

Traditionally, complex engineering applications （CEAs）, which consist of numerous components （software） and require a large amount of computing resources, usu- ally run in dedicated clusters or high performance computing （HPC） centers. Nowadays, Cloud computing system with the ability of providing massive computing resources and cus- tomizable execution environment is becoming an attractive option for CEAs. As a new type on Cloud applications, CEA also brings the challenges of dealing with Cloud resources. In this paper, we provide a comprehensive survey of Cloud resource management research for CEAs. The survey puts forward two important questions： 1） what are the main chal- lenges for CEAs to run in Clouds？ and 2） what are the prior research topics addressing these challenges？ We summarize and highlight the main challenges and prior research topics. Our work can be probably helpful to those scientists and en- gineers who are interested in running CEAs in Cloud envi- ronment.

Constraint handling is the main task in constrained optimization problems. Variable length chromosomes in the genetic algorithm has been used widely for faster computation, but in this study it was used to handle the constraint as well. This method uses the characteristic of the genetic algorithm with bit-strings conversion from real numbers. By the bit-strings format, the population of the candidates can be limited only in the study area where it is impossible when the real number format is used. Therefore, it will reduce the searching area and make the optimization process faster. Variable length chromosomes method can also be integrated with another constraint handling, i.e. the death penalty method. The results showed that the proposed method was able to optimize land use in Bekasi City, Indonesia, as a case study. © 2018 IEEE.

The ray and caustic features of the ricocheting propagation of decameter radio waves in the Earth's ionosphere have been studied. The rays and caustic structures of radio waves during trans-ionospheric channeled propagation of radiation from an elevated source are calculated using the bicharacteristics method. Ray oscillations arising during circumnavigation of the world have been studied. Using the extended bicharacteristic system method, the Jacobian of the ray flux divergence and, on its basis, the attenuation of the radio signal are calculated.
