A transform matrix between the standard feature and the subject feature is calculated. Recognition object activity data is acquired when the subject performs a recognition object activity. A recognition object feature of the subject is extracted from the recognition object activity data. The recognition...
Feature transformationtechniques reduce the dimensionality in the data by transforming data into new features.Feature selectiontechniques are preferable when transformation of variables is not possible, e.g., when there are categorical variables in the data. For a feature selection technique that is spec...

where T is the map transformation matrix and it is generally estimated by pairing two grid maps. Figure 4 depicts the indirect collaborative map merging problem involving 𝑖=1,……‥,𝑛i=1,……‥,n robots. It is important to note that each robot maintains its own individual SLAM map. ...

Another feature engineering approach transforms the original features into new ones to represent the original data, and the transformation can be accomplished through linear or non-linear methods. Most linear transformation methods are based on matrix factorization, such as Principal Component Analysis (PC...
The PFP approach takes the advantage of the features transformation and selection mechanism to map and cluster the data for the integration, and an analysis of the data features context relation using LSA to provide the appropriate index for fast and accurate data extraction. A huge volume of ...
and we use the projective transformation to obtain the homography transformation matrix. The algorithm uses the transformation matrix to transform the image and finally uses the mask to synthesize the image to realize the image matching of the cross-resolution image. Experiments have shown that our ...
