Detailed Description

header of a lnc feature file

The header of the feature file must begin with something like

 SNNS pattern definition file V3.2
 generated at Thu Apr  6 17:12:10 2000

The following lines will be ignore except for those which follow following squeme:

 [itemName]:[itemValue]

where [itemName] is a string with no colon (':') and value is a valid integer number.

The last line of the header MUST be

 # FeatureType : xyz

where xyz represents any string

There are five item-pairs, which will be directly parsed and stored in * the correspondent header attributes:

• Objects: the number of objects or classes in the file.
• No. of patterns: the number of patterns (or feature vector in the file
• No. of input units: the dimension of the feature vectors
• No. of output units: the number of classes, to which the pattern belongs. Usually 1
• FeatureType: the name of the feature stored in the file

This five pair will NOT be included in the items map when reading the file, and should NOT be present in the items map when storing the file.
