Help in loading neural network data

Hey guys I am trying to load up some data for a neural network using the back propagation algorithm. The data that I have is given in the form of 3 files - a .map file, a.data file and a .label file. This is from the 20 newsgroup data set which is quite famous in text analysis.

Could someone explain to me how I am supposed to load this data into matlab? I have tried load but I don't understand how I am supposed to use the .label and .map files. Perhaps this is done from an older version of Matlab and I want to know how to use this effectively in the newer versions (I am using R2017a)

the website I have gotten the data from is

The folder has the following files:

• train.data
• train.label
• train.map
• test.data
• test.label
• test.map

You can load the files with extension data and label using load. These files have numbers as data. The files with extension .map can be loaded using textscan

Hi i did what you said. Can you confirm if I made a mistake anywhere?

Here is the code now

clc

clear all

close all

a = load('train.data');

b = load('train.label'); fileid = fopen('train.map') c = textscan(fileid,'%s')

save('goat.txt','a','b','c')
