详细描述

The class Features is the base class of all feature objects.

It can be understood as a dense real valued feature matrix (with e.g. columns as single feature vectors), a set of strings, graphs or any other arbitrary collection of objects. As a result this class is kept very general and implements only very weak interfaces to

duplicate the Feature object
obtain the feature type (like F_DREAL, F_SHORT ...)
obtain the feature class (like Simple dense matrices, sparse or strings)
obtain the number of feature "vectors"

In addition it provides helpers to check e.g. for compatibility of feature objects.

Currently there are 3 general feature classes, which are CDenseFeatures (dense matrices), CSparseFeatures (sparse matrices), CStringFeatures (a set of strings) from which all the specific features like CDenseFeatures<float64_t> (dense real valued feature matrices) are derived.

(Multiple) Subsets (of subsets) are supported. Sub-classes may want to overwrite the subset_changed_post() method which is called automatically after each subset change. See method documentations to see how behaviour is changed when subsets are active. A subset is put onto a stack using the add_subset() method. The last added subset may be removed via remove_subset(). There is also the possibility to add subsets in place (this only stores one index vector in memory as opposed to many when add_subset() is called many times) with add_subset_in_place(). The latter does not allow to remove such modifications one-by-one.

参数

p	preprocessor to set

在文件 Features.cpp 第 85 行定义.

void add_subset ( SGVector< index_t > subset )

virtual

Adds a subset of indices on top of the current subsets (possibly subset of subset). Every call causes a new active index vector to be stored. Added subsets can be removed one-by-one. If this is not needed, add_subset_in_place() should be used (does not store intermediate index vectors)
