WebFeature extractor methods are applied to data elements with whose types they are compatible. Other data elements are returned unchanged. FeatureExtraction [examples] … Feature extraction involves reducing the number of resources required to describe a large set of data. When performing analysis of complex data one of the major problems stems from the number of variables involved. Analysis with a large number of variables generally requires a large amount of memory and computation power, also it may cause a classification algorithm to overfit to training samples and generalize poorly to new samples. Feature extraction is a general term for …
