Ah, this brings back memories. I tried something like that about 12 years ago, with a homebrewn half-hardcoded, half-neural thing and a large set of Jules Verne books.

The giddy excitement of being on the verge of unlocking the power of language slowly turned into confusion and then decayed into disappointment as i slowly realized that the task was maybe a bucket of orders of magnitude harder than i thought. I think it produced some coherent phrases every now and then, but mostly it was a random words generator.

...I miss these amplified feelings of cluelessly diving into an impossible project...

This was very wonderfully articulated! Do you have a blog or something?

Well, Orbital Designs http://orbides.org certainly qualifies as "something", but i'm not sure how much of a "blog" it really is since all of the content is indexed. :)

I like it! Very nice.

Knowledge kills the enthusiasm. One can move but doesn't know where and how, the other knows where and how, and spends the life in kotau.

Strangely enough, I find the output of Markov Chain - type text generators much more readable and coherent than the output of those RNNs. A Marov Chain text generator is also easy to implement and understand.

Interesting. Why do you think that is? (More readable, that is)

If I were going to guess (not the parent), it's because human parsing is quite localised, and Markov models tend to optimise well for localised coherence.

Their failure mode is long sentences which don't go anywhere (or mean anything), but that's less grating than a blatant parse failure, especially if you're skim reading.

That actually makes a lot of sense, great point.

Claude Shannon[1], information theory guy, worked on machine generated music quite a lot. Some of the ideas transfer. Information theory informs a lot in this area[2].

Fascinating!

I wonder how hard it would be to use a Markov chain as a syntactic filter on the output of the RNNs?

The interesting properties of RNNs aren't in readability. RNNs can learn syntactical states, e.g. "this text is in quotes" that enable some really cool analysis tricks. OpenAI published an article about this recently, where they showed that an RNN, without being trained on it, learned the difference between positive and negative reviews. The fact that an RNN encodes sentiment is an incredibly useful feature.

thanks for bringing this up! i saw this article last week and it THRILLED me. so much potential here.

I came up with similar results by just tracking word probabilities and then regenerating text based on those probabilities.

Feeding it Edgar Allen Poe produced the best results:

Here's the TED version I just generated using the input.txt from one of the linked articles: https://github.com/samim23/TED-RNN/

entertaining anyway, and occasionally amazing

Holy shit, that's awesome. Do you have the code used to generate this available somewhere?

Thanks for noticing! :) I will tidy it up and put it out there soon. I'll let you know after I've done that. :)

This is beautiful.

I've also did this a few months ago with a dump of all my telegram messages. I thought it could be a nice chatbot. I was wrong. :-(

Haha yeah it's a little disappointing (yet interesting) how it comes close but misses the mark. I wonder how far away we are to having machine-generated output that's tough to distinguish from the input you put into it.

The Obama one is much better, but the thing is none of these are even remotely close. They sort of seem close on the surface if you simply don't engage any critical parts of your brain, or try to extract any meaning, but if you do the semblance of meaning that's inherent in the words melts away into nothing.

To generate output that contained meaning that you could actually engage with, you'd have to first generate the meaning and then turn that into text. That's a fundamentally different process to what is going on here. This is also why 'Turing Test' competitions involving chat bots are never going to give us artificial intelligence.

This sort of text generation is like a magician's trick where he appears to saw the woman in half and put her together again. I don't care how good the magician is at the trick, he's not going to be any help at all to a surgeon that's actually cutting someone in half and then stitching them back together again.

> This sort of text generation is like a magician's trick where he appears to saw the woman in half and put her together again.

That's a really good analogy!

yep, this is so true. i was really excited about the tiny fragments that seemed to hold meaning, but they were obviously just happy accidents.

ohno i was totally planning on doing this next ):

Does that include starting sentences with "so"? Is anyone else annoyed by this?

Trained a neural net to write like me: poorly.

Hahaha! Yeah, maybe that's part of what makes the output distinctive. Do you have any good recommendations for a person looking to improve their shoddy writing?

Are you talking about the submission title? =/

I really want to try this on small refactoring git commits to reproduce a simple ml-based code optimization engine.

You should totally do it! Would love to see what happens.

Reminds me somehow of SCIgen (https://pdos.csail.mit.edu/archive/scigen/), a funny 'scientific paper generator'.

In a similar vein, http://git-man-page-generator.lokaltog.net/ creates plausible-sounding man pages for git internals.

The title is from the perspective of the submitter (being the husband in the original title), it should be "visakanv-RNN — machine-generated husband chatter". Which is a lot less catchy.

Wasn't expecting the image at the end, wtf?

I believe all technical articles are now required to include at least one Impact font meme. I'll see if I can dig up the RFC.

I thought it was pretty fun!

She should call this the HusBot.

this is clearly way better than visakanv-rnn. thanks!

:-)
