public class RemoteTable
extends Data
This allows the user to specify a remote data file that contains data records. This data file is then used to create input/output vectors to be used for training a arbitrary function approximators including neural networks. The attributes of each record do not have to be scalar numbers. Attributes can be binary, doubles, floats, integers, characters, words, and strings.

Methods

o getData 
 public void getData(Matrix in,
                     Matrix out,
                     Random rnd) throws MatrixException
Put the input/output pair into arrays in/out. The arrays must already have been initialized to the right sizes. A randomly-chosen data point will be returned.

Throws: MatrixException
vectors were the wrong size
Overrides:
getData in class Data
o getData 
 public void getData(int n,
                     Matrix in,
                     Matrix out) throws MatrixException
Put the nth input/output pair into arrays in/out. The arrays must already have been initialized to the right sizes. An exception is raised if n<0 or n>=nPairs. If number of pairs is infinite, then exception is always thrown.

Throws: MatrixException
vectors were the wrong size or there is no "nth" data item
Overrides:
getData in class Data
o BNF 
 public String BNF(int lang)
Overrides:
BNF in class Data
o unparse 
 public void unparse(Unparser u,
                     int lang)
Output a description of this object that can be parsed with parse().

Overrides:
unparse in class Data

Parsable
o parse 
 public Object parse(Parser p,
                     int lang) throws ParserException
Parse the input file to get the parameters for this object.

Throws: ParserException
parser didn't find the required token
Overrides:
parse in class Data
