Also note that there's OnionShare, too. You don't need a TLS certificate or domain, don't need to port forward and can run it from home safely, routes over Tor so very hard to know you are even sharing something, well known and open source etc.

Thanks for the answer! I hadn't thought about asking for recipes based on the specific ingredients you have left.

[–] [email protected] 2 points 5 days ago (2 children)

More importantly, what was the recipe and was it any good?

Thanks for your answer. I think to be clear, what I'm looking for is a kind of masked fine-tuning. You see, I want to "steer" a particular output instead of providing complete examples, which are costly to create.

The steering would be something like this:

  1. I have an LLM generate a sequence.
  2. I find exactly where the LLM goes "off track" and correct it there (for only maybe 10-20 tokens instead of correcting the rest of the generation manually).
  3. The LLM continues "on track" until it goes off track again.

What I would like to do is train the model based on these corrections I give it, where many corrections might be part of the same overall generation. Conceptually I think each correction must have some training value. I don't know much about masking, but what I mean here is that I don't want it to train on a few tens or hundreds of (incomplete) samples but rather thousands of (masked) "steers" that correct the course of the rest of the sample's generated text.

Sorry, I really don't care to continue talking about the difference between supervised and unsupervised learning. It's a pattern used to describe how you are doing ML. It's not a property of a dataset (you wouldn't call Dataset A "unsupervised"). Read the Wikipedia articles for more details.

No, in that case there's no labelling required. That would be unsupervised learning.

https://en.wikipedia.org/wiki/Unsupervised_learning

Conceptually, unsupervised learning divides into the aspects of data, training, algorithm, and downstream applications. Typically, the dataset is harvested cheaply "in the wild", such as massive text corpus obtained by web crawling, with only minor filtering (such as Common Crawl). This compares favorably to supervised learning, where the dataset (such as the ImageNet1000) is typically constructed manually, which is much more expensive.

Ground truth labels are just prescriptive labels that we recognize as being true. The main thing that distinguishes unsupervised from supervised is that in unsupervised learning, what is "good" is learned from the unstructured data itself. In supervised learning, what is "good" is learned from some external input, like "good" human-provided examples.

No, it's unsupervised. In pre-training, the text data isn't structured at all. It's books, documents, online sources, all put together.

Supervised learning uses data with "ground truth" labels.

This pre-training was done by Meta. It's what Llama-3.1-405B is (in contrast to Llama-3.1-405B-Instruct). https://huggingface.co/meta-llama/Llama-3.1-405B

Training Data

Overview: Llama 3.1 was pretrained on ~15 trillion tokens of data from publicly available sources. The fine-tuning data includes publicly available instruction datasets, as well as over 25M synthetically generated examples.

Unsupervised training happens during the pre-training phase when you dump all kinds of quality documents and it learns the relationship between tokens

Curious, how do you evaluate the performance without breaking the law?

[–] [email protected] 1 points 1 month ago (13 children)

The article you linked to uses SFT (supervised fine tuning, a specific training technique) as its alignment strategy. There are other ways to fine-tune a model.

I guess I'm wondering if you can train on these partial responses without needing the full rest of the output, without the stop token, or if you need full examples as the article hints to.

I want to fine tune an LLM to "steer" it in the right direction. I have plenty of training examples in which I stop the generation early and correct the output to go in the right direction, and then resume generation.

Basically, for my dataset doing 100 "steers" on a single task is much cheaper than having to correct 100 full generations completely, and I think each of these "steer" operations has value and could be used for training.

So maybe I'm looking for some kind of localized DPO. Does anyone know if something like this exists?

 

People are talking about the new Llama 3.3 70b release, which has generally better performance than Llama 3.1 (approaching 3.1's 405b performance): https://www.llama.com/docs/model-cards-and-prompt-formats/llama3_3

However, something to note:

Llama 3.3 70B is provided only as an instruction-tuned model; a pretrained version is not available.

Is this the end of open-weight pretrained models from Meta, or is Llama 3.3 70b instruct just a better-instruction-tuned version of a 3.1 pretrained model?

Comparing the model cards: 3.1: https://github.com/meta-llama/llama-models/blob/main/models/llama3_1/MODEL_CARD.md 3.3: https://github.com/meta-llama/llama-models/blob/main/models/llama3_3/MODEL_CARD.md

The same knowledge cutoff, same amount of training data, and same training time give me hope that it's just a better finetune of maybe Llama 3.1 405b.

 

I've been waiting for an open source TTS model that was actually good enough to capture some of the subtleties of language and synthesize them in a natural-sounding way that makes sense. I think I finally found one that fits the requirements.

Model: https://huggingface.co/fishaudio/fish-speech-1.5

It uses an encoder rather than relying on phonemes, and generations sometimes vary because of that, but the amount of errors I've gotten are minimal, and the variations in the generation are all surprisingly natural in slightly different ways, which is very exciting.

Give it a spin if you are also looking for a TTS model that sounds good. It uses voice cloning, so find a good 10-20 second reference clip to have the generations use the same voice.

 

I'd like to fine tune a model that does img2img with a text prompt to guide the output. I think img2img-turbo might be the closest to what I'm after, though by default it uses a fixed prompt which can be made variable with some tweaking of the training code.

At the moment I only have access to 24GB VRAM which limits my options. What I'm after is training a model to make specific text-based modifications to images, and I have plenty of before to after images plus the modification text prompts to train on. Worst case, I can try to see if reducing the image size during training makes it possible with my setup.

Are there any other options available today?

 

I have thousands of side-by-side translations for two computer languages (lower level to higher level), and I would like to train a model that is able to do translations on new data with higher accuracy.

Got any suggestions on what to do? I don't think I want to fine tune a ChatGPT-style model since I think the task is more structured than that. Also, I consider myself technically competent but probably would fail at designing my own model and pipeline.
