Generally speaking, sentiment lexicons employed in the majority of current sentiment analysis systems are trained globally from public data stream source or other large independent corpus. However, sentiments are rather subjective and personal states of mind that the individuality and diversity of characteristics, particular writing habit and idiolect could play a crucial role in the judgment of sentiment...
Support vector machine (SVM) has been widely applied in flood forecasting models and achieved good results. However, it has been plagued by two problems. One is its over-reliance on the number and quality of the raw input data; the other is that a single model cannot describe the complex relationships hidden in the flood evolution processes. To tackle the two problems, this paper presents an SVM flood...
This paper presents a testing method of surface roughness for the surface with straight features using image processing. This approach extracts the average texture cycle to describe the surface roughness of mechanical accessory. After surface images of the standard blocks with different roughness levels are collected, the feature value of the average texture cycle which is processed by Matlab software...
For features of synchronous orbit target image, this paper proposes the small target detection method that based on Normalized moment of inertia feature. Firstly, this method uses gray mathematical morphological filter to pre-process the image, improves the target signal noise ratio without affecting the target shape, and then uses constant false alarm rate (CFAR) to choose segmentation threshold...
