I wonder how they tested that

wow I’d love to read the Marxist and anarchist texts it has produced. I wonder if they used good source material.

I would bet it gets the talking points but can’t convey the subtlety.

I bet anyone who bothers to read them twice realizes it's nonsensical

Surely we are not far off models capable of submission-quality essays that will enable a new generation of cheating.

From my observation, even the largest GPT-2 model has difficulty retaining any long-range relationship information. In the "unicorn" writing example that was published originally, the model 'forgets' where the researchers are (climbing a mountain versus being beside a lake iirc) after just a few sentences. Because of this, it's hard to imagine models of this type being able to write long-form coherent papers. Now if we could somehow constrain the generated text to conform to a predefined graph structure that isn't forgotten so quickly...

Sorry for asking but is there an example output and an example input?

Not the full model, but there are some pretty funny examples on https://www.reddit.com/r/SubSimulatorGPT2/

It's a subreddit which consists entirely of posts and comments by GPT-2 bots (with votes by humans). There's a variety of different bots fine-tuned on posts and comments from different subreddits, so depending on which bot is posting you can get wildly different results.

If anyone wants to fine-tune the 1.5B model, I ported the gpt-2 code to TPUs. You can fine-tune it in Colab. Snapshots are 5.8GB.

code: https://github.com/shawwn/gpt-2

It's a fork of nshepperd's gpt-2 codebase (https://github.com/nshepperd/gpt-2) which lets you fine-tune 117M and 345M on GPUs.

Is hegelianism a better ideology? I don’t understand the underlying message.

Maybe the problem is that most of these models seem to rely on sequential information (even the transformer needs this for forward generation of text) to encode long range information.

But I can’t remember the last time I relied on sequentially remembering the ordering of tokens in order to complete an essay or hell even reply to an email.

Structurally we retain some kind of hierarchical information (topic, places, names, events) about text.

Is there any active research looking into text generation models which do this? Maybe some kind of query that is made in a learned vector space and which is not temporarily dependent but rather “spatially” - as in these are the facts about the text being generated so far.
