-# id2vec
+# id2vec
+
+**Operating id2vec on an Ubuntu machine:
+
+First, run the following commands:
+
+```bash
+cd /path/to/id2vec
+dos2unix init.sh preprocess.sh train.sh scripts/splitData.sh
+chmod 744 init.sh preprocess.sh train.sh
+```
+
+Then run init.sh in order to install necessary packages:
+./init.sh
+
+Then, remove unnecessary files and split the data before preprocessing it:
+find raw_data ! -name '*.ts' -type f -exec rm -f {} +
+scripts/splitData.sh raw_data 80
+cd raw_data
+mv train_dir train_dir_tmp
+../scripts/splitData.sh train_dir_tmp 80
+mv train_dir_tmp/test_dir train_dir_tmp/val_dir
+mv train_dir_tmp/* .
+cd ..
+rmdir raw_data/train_dir_tmp
+
+To preprocess, run the following commands inside a shell of your ubuntu machine in order for the script to run in the background:
+./preprocess.sh &
+disown
+
+Explanation: the & literal disconnects stdin from the process that runs the preprocess.sh script,
+and returns it to your shell. Then, the disown command removes the process from the shell's job control. This way,
+even if your terminal session is terminated (as happens when your ssh connection to the machine is terminated)
+the process will continue running in the background.
