I have some basic confusions over how to prepare a dataset for training. My plan is to use a model like llama2 7b chat, and train it on some proprietary data I have (in its raw format, this data is very similar to a text book). Do I need to find a way to reformat this large amount of text into a bunch of pairs like “query” and “output” ?

I have seen some LLM’s which say things like “trained on Wikipedia” which seems like they were able to train it on that large chunk of text alone without reformatting it into data pairs - is there a way I can do that, too? Or since I want to target a chat model, I have to find a way to convert the data into pairs which basically serve as examples of proper input and output?

    Trained and finetuned - 2 things.

    The trained on wikipedia - yes, they feed the wikipedia articles to it - hook and sinker. No Q/A. But that doesn’t mean it will be able to give you answer, unless you fine tune it with Q/A “I want you to behave like this” template - but the kick is - what we all are using to our huge advantage - it can be fine-tuned on a totally different Q/A, it will still be able to answer from wikipedia. It’s a hat trick.

      I am new to LLMs (I normally train Image Models) so if this is a stupid question let me know.

      I have been converting the shadowrun lore wiki into Q and A so i can use that model for a sillytavern character as a contact in my current tabletop game. Do I really need to convert it all to Q and A? If I get a better “Contact” I dont mind.

    if you’re making a lora, training on wikipedia directly will pretty much make it output text that looks like wikipedia. which is to say it will (probably) be worse at chatting.

    a strategy i’ve been using lately is to get gpt4 to make a conversation in my chosen format *about* each chapter of my “textbook”, i can automate this with pretty good results and it’s done in about 10 minutes. It does kind of work, it’ll at least get the bot to talk about the topics I chose, but as far as actually comprehending the information it’s referencing… it’s bad. It gets better as I increase rank, but it takes a lot of VRAM. I can only get to around 256 before it’ll die

    Go to huggingface and look at the multitude of datsets that have already been prepped and read whatever documentation and papers that have been published. Go through the data and get a sense of what the data looks like and how it’s structured.

      Yea, doing this is part of what spurred the question, because I began to notice some datasets that were very clean and ordered into data pairs, and others that seemed formatted differently, and others still that seemed like they were fed a massive chunk of unstructured text. It made me confused on if there were some sort of standards or not that I was not aware of.
