Description: We propose an algorithm for facial expression recognition which can classify the given image into one of the seven basic facial expression categories (happiness, sadness, fear, surprise, anger, disgust and neutral). PCA is used for dimensionality reduction in input data while retaining those characteristics of the data set that contribute most to its variance, by keeping lower-order principal components and ignoring higher-order ones. Such low-order components contain the "most important" aspects of the data. The extracted feature vectors in the reduced space are used to train the supervised Neural Network classifier. This approach results extremely powerful because it does not require the detection of any reference point or node grid. The proposed method is fast and can be used for real-time applications.

Description: ExtJS是一种主要用于创建前端用户界面，是一个与后台技术无关的前端ajax框架。 功能丰富，无人能出其右。 无论是界面之美，还是功能之强，ext的表格控件都高居榜首。 单选行，多选行，高亮显示选中的行，推拽改变列宽度，按列排序，这些基本功能咱们就不提了。 自动生成行号，支持checkbox全选，动态选择显示哪些列，支持本地以及远程分页，可以对单元格按照自己的想法进行渲染，这些也算可以想到的功能。 再加上可编辑grid，添加新行，删除一或多行，提示脏数据，推拽改变grid大小，grid之间拖拽一或多行，甚至可以在tree和grid之间进行拖拽，啊，这些功能实在太神奇了。更令人惊叹的是，这些功能竟然都在ext表格控件里实现了。 -ExtJS is a major front-end user interface for creating, is a front-end and back-end technology has nothing to do ajax framework. Feature-rich, no one can match his. Whether it is the beauty of the interface or function of the strong, ext topped the table controls. Radio lines, multiple-choice line, highlight the selected row, push pull to change the column width, sorting by columns, these basic functions we will not mention. Automatic generation of line numbers, support checkbox select all, select which columns are displayed dynamically, supporting local and remote paging, the cells can be rendered in accordance with their own ideas, they can think of functions are also considered. Together with an editable grid, add new rows, delete one or more lines, suggesting that dirty data, push pull change the grid size, grid lines between the drag and drop one or more, even in the tree and drag and drop between grid, ah These features really amazing. Even more amazing is that these functions ar

Description: Feature selection methods for machine learning algorithms such as SVR, including one filter-based method (CFS) and two wrapper-based methods (GA and PSO). The gridsearch is for the grid search for the optimal hyperparemeters of SVR. The SVM_CV is for the k-fold cross-validation of SVR. All the programs are flexible and could be implemented by the users themselves.-Feature selection methods for machine learning algorithms such as SVR, including one filter-based method (CFS) and two wrapper-based methods (GA and PSO).

Description: Histogram of Oriented Gradients (HOG) are feature descriptors used in computer vision and image processing for the purpose of object detection. The technique counts occurrences of gradient orientation in localized portions of an image. This method is similar to that of edge orientation histograms, scale-invariant feature transform descriptors, and shape contexts, but differs in that it is computed on a dense grid of uniformly spaced cells and uses overlapping local contrast normalization for improved accuracy.

Description: 特征提取是手写体汉字识别的关键，目前四方向网格特征已被实验证实是一种较好的手写体汉字特征。
针对通常的纵横弹性网格对汉字“撇、捺”笔画特征提取的不足．提出一种新的网格构造技术——对角弹性网格，它由45度和135度的对角直线构成，将汉字图像划分为多个菱形，能够很好地适应汉字在“撇、捺”方向的变化。将这两种网格单独，以及相互组合成双网格等情况分别进行手写体识别实验，实验结果验证了对角弹性网格的有效性和双弹性网格的高识别率性。
-Feature extraction is the key to handwritten Chinese character recognition. At present, the four-way grid feature has been proved to be a good handwritten Chinese character.
In view of the shortcomings of the traditional vertical and horizontal elastic grid on the extraction of Chinese characters write and tear . A new grid construction technique, diagonal elastic grid, is proposed, which consists of 45 degree and 135 degree diagonal straight lines. The Chinese characters are divided into multiple diamonds, which can adapt well to Chinese characters. The direction of change. The experimental results verify the effectiveness of the diagonal elastic grids and the high recognition rate of the double elastic grids. The experimental results verify the effectiveness of the diagonal elastic grids and the high recognition rate of the birefringence grids.
