[D] Machine Learning - WAYR (What Are You Reading) - Week 16

This is a place to share machine learning research papers, journals, and articles that you're reading this week.
If it relates to what you're researching, by all means elaborate and give us your insight, otherwise it could just be an interesting paper you've read.

Please try to provide some insight from your understanding and please don't post things which are present in wiki.

Preferably you should link the arxiv page (not the PDF, you can easily access the PDF from the summary page but not the other way around) or any other pertinent links.

Django vS other Dev frameworks

Hi can someone explain to me in laymens terms the perks of developing applications quickly within the django framework as opposed to writing logic by hand with JS and using that to interact with my html/css? I am currently working with python for my applications due to it's ease of transferring ideas to code. However I am still unsure about how to make the GUI/front-end is that all still done with standard HTML/css and django/python is back-end/database interaction ? Would love to get a discussion going, hope everyones having a good boxing day.

I accidentally uploaded my secret key onto a public github repo for a trivial practice app--am I under any serious threat for anything?

It was a side project I did for practice, but would like to keep it on github to keep record of my progress.

What sort of risk am I taking in making my secret key available?

side question: when uploading a django app onto GH, what sort of security measures should I take from now on? What belongs in the .gitignores of django apps?

[D] How to train generative adversarial networks

We have had a few posts here before, and the [notes of the talk at NIPS](https://github.com/soumith/ganhacks) are useful, and there are some other great "how to" [resources](https://github.com/shekkizh/neuralnetworks.thought-experiments/blob/master/Generative%20Models/GAN/Readme.md). There is also the [Torch blogpost on the topic](http://torch.ch/blog/2015/11/13/gan.html).

I have generated images that look good. I have toyed with tons of GAN variants.

But I still feel like I have no idea how to train a GAN in any sort of rigorous manner. To me it seems like the most important factor in generating visually understandable images is some strange and exploratory architecture balancing act, which appears completely arbitrary. I train one GAN to equilibrium and end up with trash images, but change a tiny thing in the architecture and reach a very similar equilibrium (ie the G and D training curves look the same) but have nice images.

This suggests to me that what we are actually doing is (over)fitting models based on human visual interpretation, not model metrics. This is very "human in the loop" and not theoretically satisfying. And more frustratingly, it is not discussed even in the few articles and blogposts on GAN hacks and methods. I wasn't at NIPS so I don't know if the workshop covered more than the git.

Mode collapse and "stability" don't seem to explain my experiences. It kind of feels more like model hacking. I know my colleagues feel similar frustrations, like we are all just randomly wandering around image space until we stumble upon a training method that lands us close to the image manifold and then it magically starts working.

I really want to be told I am just missing something that should be obvious.

So, is there any rigorous way to train a GAN? Where I can look at my curves and my gradients and my activations and just *know* I will end up with quality images?

Running django models on a server

I've currently built a data collector script that requests data from an API and stores it in a mongo database. Eventually I want to display this data via a django app however first i'd like to host the script on a server where it can collect data without my computer being on.

Later I will connect my django app to the db that is hosted on the server. However for now I want to know the best way to host my data collector and db.

Would you guys recommend apache ?

NB I'm new to hosting scripts on servers/ django, so any noobie notes would be great

EDIT: Can i run it directly through django with it's own server ?

jsonencoder

hello again dont mean to be a pain in the rear but i really need help serializing sqlalchemy data to json to be able to use in jquery

class User(db.Model):

__tablename__ = 'user'

id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(100), unique=True)
email = db.Column(db.Binary)
password = db.Column(db.Binary)
role = db.Column(db.String(8))
profilepic = db.Column(db.String())

picture = db.relationship('Picture', backref='owner', lazy='dynamic')
comment = db.relationship('Comment', backref='user', lazy='dynamic')

def __init__(self, username, email, password, role, **kwargs):
self.username = username
self.email = email
self.password = password
self.role = role

i have tried marshmallow but its hard for me to understand i would really appreciate the help
