摘要:
This paper presents 15 SVM models optimized by machine learning methods in water quality assessment. Through comparative analysis, we found that all the models reached reasonable accuracy during the training and testing process. In particular, SAA-SVM-PI, GWO-SVM-PI, GWO-SVM-TN, PSO-SVM-TP models have the highest accuracy, the highest squared correlation and the lowest mean squared error when testing the three indexes of PI, TN and TP. In order to study the spatial distribution characteristics of water quality in Dongting Lake, GWO-SVM-PI, GWO-SVM-TN and PSO-SVM-TP models were respectively used for single-factor water quality classification. The results showed that: As far as the PI is concerned, the water quality is mainly in grade I and II; As far as TN is concerned, the water quality is mainly of grade IV and V, with the worst water quality in the East Dongting Lake and the outlet profile; In terms of TP, the water quality is mainly of grade III, IV and V, with the best inlet water quality, the worst water quality in the South Dongting Lake.

摘要:
Water quality assessment is an essential part of water resource management. This paper presents a new GWO-SVM method for water quality assessment. Through comparison with GS-SVM and GA-SVM, we found that GWO-SVM model has the highest accuracy, the highest squared correlation and the lowest mean squared error when testing the three indexes of PI, TN and TP.The GWO-SVM model proposed in this paper was used to analyze the water quality data of Dongting Lake from 1993 to 2012. The results showed that: As far As the PI is concerned, the water quality is mainly in grade I and II, with the best water quality in autumn and 2008-2012.As far As TN is concerned, the water quality is mainly of grade IV and V,With the best water quality in autumn and the worst in spring, water quality was the best from 2003 to 2007 and the worst from 2008 to 2012.In terms of TP, the water quality is mainly of grade III,IV and V, with the best inlet water quality, the worst water quality In the south dongting lake, the best water quality In summer,The best water quality between 1993 and 1997, and the worst water quality between 2003 and 2007.

摘要:
Parameters optimization is a research hotspot of SVM and has gained increasing interest from various research fields. Compared with other optimization algorithms, genetic-based evolutionary algorithms that have achieved optimization according to the laws of separation and free combination in genetics are gradually attracted much attention. Also, due to the characteristics of self-organization and self-adaptation, these algorithms often enable SVM to obtain appropriate parameters, so that the model can be applied to more applications. Additionally, many improvements have been proposed in the past two decades in order to allow the optimized SVM model to obtain better performance. This work focuses on reviewing the current state of genetic-based evolutionary algorithms used to optimize parameters of SVM and its variants. First, we introduce the principles of SVM and provide a survey on optimization methods of its parameters. Then we propose a taxonomy of improving genetic-based evolutionary algorithms according to code mechanism, parameters control, population structure, evolutionary strategy, operation mechanism, operators, and many other hybrid approaches. Furthermore, this paper analyzes and compares the advantages and disadvantages of the above algorithms explicitly, and provides their applicable scenarios as well. Finally, we highlight the existing problems of genetic-based evolutionary algorithms used for parameters optimization of SVM and prospect development trends of this field in the future.

摘要:
Multi-label stream classification has not been fully explored for the unique properties of large data volumes, realtime, label dependencies, etc. Some methods try to take into account label dependencies, but they only focus on the existing frequent label combinations, leading to worse performance for multi-label classification. To deal with these problems, this paper proposes an algorithm which dynamically recognizes some new frequent label combinations and updates the trained classifier by class incremental learning strategy. Experimental results over both real-world and synthetic datasets demonstrate its better predictive performance.
