DATA >ATTRIBUTE
PURPOSE Create a network from attribute data.
DESCRIPTION Convert a vector of valued attributes to a matrix based upon either exact matches, differences, absolute differences, squared differences, product or sums of the values.
PARAMETERS
Dataset containing attribute vector:
Name of data file containing vector of valued attributes. This vector must be a row or column of a matrix , it can be the only row or column. Data type: Matrix
Vector is Row or Column?:
Choose either row or column
Which Row/Col (Default = 1)
The number of the row or column that contains the attributes to be converted.
Method: (Default = Absolute Difference).
Choices are:
Exact Matches
Matrix X is formed by X(i,j) = 1 if vector(i) = vector(j) and 0 otherwise.
Difference
Matrix X is formed by X(i,j) = vector(i) - vector(j).
Absolute Difference
Matrix X is formed by X(i,j) = ABS (Vector(i) - vector(j)).
Squared Difference
Matrix X is formed by X(i,j) = (vector(i) - vector(j))^2.
Product
Matrix X is formed by X(i,j) = vector(i) * vector(j).
Sum
Matrix X is formed by X(i,j) = vector(i) + vector(j).
Output dataset:
Name of file which contains constructed matrix.
LOG FILE Constructed matrix.
TIMING O(N^2).
