_VlAIB Struct Reference
#include <aib.h>
Detailed Description
For internal use only.
The implementation is quite straightforward, but the way feature values are handled in order to support efficient joins, deletions and re-arrangement needs to be explained. This is achieved by adding a layer of indirection:
- Call each feature value (either original or obtained by a join operation) a node. Nodes are identified by numbers.
- Call each element of the various arrays (such as VlAIB::Px) an entry.
- Entries are dynamically associated to nodes as specified by VlAIB::nodes. For example,
Px
[i] refers to the nodenodes
[i].
