说明

fann_merge_train_data ( resource $data1 , resource $data2 ) : resource

将 data1 和 data2 数据集合并为新的训练数据 resource.

参数

data1: 神经网络训练数据资源。
data2: 神经网络训练数据资源。

返回值

There will be times when you need to merge separate data sets into a new single set. 



This code demonstrates how to merge the XOR dataset from two separate files into a single training file.



File (xor_part_1.data):

1 2 1

-1 -1

-1



File (xor_part_2.data):

3 2 1

-1 1

1

1 -1

1

1 1

-1



Resulting File (xor_complete.data):

4 2 1

-1 -1 

-1 

-1 1 

1 

1 -1 

1 

1 1 

-1 



<?php

// Create partial data resources

$train_data_1 = fann_read_train_from_file("xor_part_1.data");

$train_data_2 = fann_read_train_from_file("xor_part_2.data");



// Merge into new data resource

$train_data = fann_merge_train_data ($train_data_1, $train_data_2);



// Remove the partial data resources from memory 

fann_destroy_train ( $train_data_1 );

fann_destroy_train ( $train_data_2 );



// Save the new complete Data file

fann_save_train ( $train_data , "xor_complete.data");



// Remove the complete data resources from memory 

fann_destroy_train ( $train_data );



echo 'All Done!' . PHP_EOL;
