Description: 在图 像 拼 接中通常使用模板匹配方法进行图像配准,模板特征选取、基准模板位
置与大小选取,在很大程度上影响图像配准的准确度和速度。基于模板匹配的原理,文中提出了两种新的彩色图像自动拼接方法,基于三基色原理的平行线寻优法和十字交叉特征寻优法-In the image mosaic is usually carried out using a template matching method image registration, the template feature selection, location and size of the baseline template to select, to a large extent the impact of image registration accuracy and speed. Based on template matching principle, the text put forward two new color image automatic splicing method, based on the trichromatic principle of optimization of parallel lines and the characteristics of cross-optimizing method Platform: |

Description: Feature Selection using Matlab.
The DEMO includes 5 feature selection algorithms:
• Sequential Forward Selection (SFS)
• Sequential Floating Forward Selection (SFFS)
• Sequential Backward Selection (SBS)
• Sequential Floating Backward Selection (SFBS)
• ReliefF
Two CCR estimation methods:
• Cross-validation
• Resubstitution
After selecting the best feature subset, the classifier obtained can be used for classifying any pattern.
Figure: Upper panel is the pattern x feature matrix
Lower panel left are the features selected
Lower panel right is the CCR curve during feature selection steps
Right panel is the classification results of some patterns.
This software was developed using Matlab 7.5 and Windows XP.

Description: 随着全球的商业竞争愈来愈激烈,客户流失预测已经成为客户关系管理中非常重要的内容。预测即将流失的客户,并制定相应的措施挽留客户已经成为促进企业发展的关键性因素。本文从对电信和信用卡客户的行为数据分析入手,针对其中的冗余特征和正负类样本不均衡等特点,提出一种新的特征选择算法和非均衡数据处理算法,以此建立一种新的客户流失预测模型。(Along with the global business more competitive, customer churn prediction has become the most important content in customer relationship management. Predicting customer retention and formulating corresponding customer churn strategies has become a key factor in promoting enterprise development. Based on the analysis of customer behavior data, aiming at the redundant features and unbalanced positive and negative samples in customer data, this paper puts forward a new feature selection algorithm and unbalanced data processing algorithm, respectively, to establish a new customer churn prediction model.)
