# '''To general users:''' your  Your input file (usually a single ".txt" file contains many exampleseach as a row) will be split into a training set (80% by default) and a testing set (20% by default). The target labels you want to predict will be the sub-folder names. The description content (usually a block of text) of each example the examples will go into a separate ".txt" files. To run the script, you basically need to specify the following:  1. "File Name" : without the ".txt" extension, 2. "Expected Columns" : total number of columns in the input file 3. "Content Index" : the column index of the content 4. "Label Index" : the column index of the label The script will generate a pickle file with an ".pkl" extension and the name of will be the same as your input. Please change the name properly to indicate the label information as have been discussed above. And place this pickle file can be determined by under the usersame directory with your classification code, i. e. "classification_MMM_LLL.py" '''To process your own datasetadvanced users:'''  1. One important step in data preprocessing is to encode words (strings) into integers. The solution is to build a dictionary mapping words to their corresponding indices. For example, let's say "hello" is the 17th words in our dictionary and thus "hello" is encoded to 17. Our advanced dictionary is ordered by the words' frequency. Higher the frequency smaller the index. That is you basically need should expect to specify see "the file name" and "a" these words with very small indices. Please also notice that 0 and 1 these two indices are not assigned to any words intentionally. The advantage here is that you can easily ignore those very common and meaningless words, expected columnslike "the", content index by simply saying I only want to consider words with the indices > 20 for example. Notice that it's possible to encounter words that are not in our dictionary and label we will alway assign them to index1. These words are safe to ignore given that our dictionary is big enough.  2. Saving a pickle file is an very efficient way to retrieve the data so that you don't need to do data preprocessing every time when you want to run your classifier.
