iPhone Mounting

Linux, Unpolished Gems,

The beauty of love is not in your beauty but in your ability to make it manifest.

Mostly because I have had to look up how to mount an iPhone on Linux Mint 18.0 a few times and had to look it up,I made a helper script. – iPhone-mount.sh

#!/bin/bash
 # Allow non-root users to mount with ifuse!
 #sudo nano /etc/fuse.conf
 # Allow non-root users to specify the allow_other or allow_root mount op$
 # UNCOMMENT user_allow_other

# Pair the iPhone
 idevicepair pair
 sleep 5
 # Mount it
 ifuse /home/erick/iPhone

Allow users to mount via ifuse

In /etc/fuse.conf uncomment user_allow_other to let users mount devices. This makes it easy to mount the device in your home directory for instance with full access to it.

Mint and Mounting

The iPhone mounts fine on Mint 18.0. My desktop has a newer version and I had to do work to it before mounting the iPhone worked. Apparently something got lost between versions.

RNN Text Generation Using Tensorflow

Machine Learning, Text Generation, , , ,

Imagination is the power to make a difference in yourself.

After trying a few RNNa and LSTMs for text generation that rely on numpy alone it is interesting to see the performance of Tensorflow based code that is closer to the cutting edge of what is possible to do with machine learning.

I found a good and easy to use set of code in the following Github archive…

https://github.com/spiglerg/RNN_Text_Generation_Tensorflow

The requirements are simple…

numpy==1.13.3
tensorflow==1.4.0

I was running it on Conda Python 3.6 environment but, this is not a requirement. The code uses a saved folder where it can save training checkpoints, so it is possible to interrupt and resume training and also use it in a generate or “talk” mode after the model has been trained. The caveat that I learned quickly when training on a few types of files is when training each type of file that is trained into requires it’s own set of checkpoints, which is pretty obvious. So it is best to either wipe out the saved dir contents after a run on a specific corpus. OR, better yet make a subdir for the training checkpoints.

Training is basically sending it the following command…

python rnn_tf.py --input_file=data/us-constitution.txt --ckpt_file="saved/model.ckpt" --mode=train

Once trained it can be fed another command…

python rnn_tf.py --input_file=us-const-lstm/us-constitution.txt --ckpt_file="saved/model.ckpt" --test_prefix="The " --mode=talk

or if the checkpoint files have been moved to their own directory then you can use something like this…

python rnn_tf.py --input_file=us-const-lstm/us-constitution.txt --ckpt_file="saved/us-const-trained/model.ckpt" --test_prefix="The " --mode=talk

In the structure for the commands the location of the file is listed and the location of the checkpoint file as well. The generate mode allows priming with a word or phrase such as “The”.

The US Constitution is not a big corpus and I am sure this code like others would benefit from training against a larger corpus. My intent in the future for an experiment is to train it against a file containing all the posts on this site to see what it can do on that corpus.

When trained on the US Constitution it does very well at producing coherent text. Besides the lack of capitalization it seems to be actually to the point of memorizing parts of the text. This might be because it is a small corpus and it is overfitting.

Training

Training against the corpus of blog posts on this site produced output like this and took about 4 hours of compute time.

The following is some samples of the output it generates. It definitely could use more training to help it. The fact that the posts contain some code, numbers and jargon probably doesn’t help either.
