Small-Scale Question Sunday for April 7, 2024

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Thanks! Maybe you'll mind answering two questions: About using local models, can it be tweaked so it doesn't forget context so easily? Maybe using learning runs on previous conversations? How does chatGPT retains context? I understand it does multiple processings for each prompt, and does lossy compression of previous chat history. How to simulate in in API?

You can finetune models on your personal data or information, but that only does so much. If you're more technically inclined, you can try setting up Retrieval-augmented generation, where the model queries and existing database and tries to answer based off the knowledge there and not just what it came baked in with.

Don't ask me how that can be done, but I know it's a thing. My PC isn't good enough to fuck around with the local models worth using, courtesy of Nvidia and their stingy amounts of VRAM.

How does chatGPT retains context?

I presume you're not talking about nitty gritty algorithmic details (which would be the self-attention mechanism IIRC) and instead mean how it continues a conversation or remembers details about a user?

Well, the official implementation has a "memory" feature where it gets to remember tidbits about your preferences as a user, as well as some relevant personal details like location.

The way it works is that the entire conversation is fed back to the model, with specific signs that tell it when it or the user was speaking, and it'll resume where the user left off. I think the API works this way by default, but my OAI credits expired ages ago, so if it seems to be treating each input as a fresh prompt, you need one of the many frontends available that use your API key and then handles the matter of copying back your entire conversation, which is tantamount to the model "remembering" it.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
