"Optimizing Data Transformation with GPT-4"

Jan 11, 2024 - 10:30pmSummary: The individual has discovered that working backward from a desired result with a large language model is surprisingly effective, especially when detailing the problem forward seems challenging. This backward approach has simplified the problem and resulted in the use of GPT-4 for data transformation within the context window, improving the process. An automatic metadata generation pipeline is emerging, where data transformations are added as needed, potentially storing transformations for future use based on query relevance. This system will generate an extensive amount of synthetic data, allowing for the extraction of relevant information through queries fed into the model at later stages, rather than having to pre-determine all questions.

Transcript: It's funny, with the large language model stuff, working backwards from the answer that I want has seemed to help more than trying to work forward from the large language model, which is very interesting in terms of how it reasons, where, like, I'm working backwards through a problem and it has to, like, write things down on a piece of paper before it continues, which is really fascinating to think about the differences, like, it's hard for me to work this problem forwards, actually. I mean, like, I can just intuit about it forwards, but to then describe it effectively to a large language model, I'm working it backwards. Interesting. But I think, I mean, made decent progress at the very least. I think the problem has been simplified by working backwards in this way. So the last step of the pipeline is just, like, do a data transformation, more or less. And initially I was using, like, a small stupid model to do that, and instead it's just like, okay, we're just going to use GPT-4 and shove everything in the context window under a certain size and do that, and that'll be good enough. And indeed that's what we're going to do. So given that, like, it's helping me start to figure out some aspect of training data as well, like what data I will need to train. And then also it is effectively generating tons of synthetic pairs. So I will want to generate individual synthetic pairs as well. This is something that I'm thinking about after this next step gets done effectively. After this step is done, well, then we can go and basically what we'll want to do is remove whatever transform we're doing. So if we've transformed some data, we're going to want to go back to the metadata field, look at the unstructured data, and just immediately run that transformation on that piece of data. And if there is nothing to be transformed, we'll just output null, and nothing will go back into the metadata file. But this is effectively going to be automatically adding steps to the pipeline. That's kind of what's happening here. You ask it a question, and it's going to go and just add that data to the pipeline. Initially, none of that data is going to be used probably, but in the future, what would be great is to effectively cache those transformations and have a description of what the transformations that you have are on any piece of data. And if that transformation matches up with the user's query in any reasonable way, and again, maybe this is using embeddings or something, or maybe just a large language model that's tuned to it, it goes and does that. But this is going to be effectively like an automatic metadata generation system that will hopefully continuously improve. And we're just going to generate a massive amount of synthetic data over whatever data we put in. And I don't need to come up with all of the questions for the data in advance, because I can go and ask those questions later to get the relevant data I want out of it. And that is going to be kind of what we are really doing initially.

"Enhancing Contextual Integration with GPT-4: An Experimental Approach"

In envisioning an ideal way to integrate new log entries, the goal is to place each entry within the larger context of the whole, which may be an iterative process to determine that context. The author contemplates whether incorporating various data sources into a language model like GPT-4 could help it understand the overarching themes of communications, such as text messages. They propose an experimental approach by loading as much context as possible into the model whenever a new input is received, maximizing the token limit to allow the model to contextualize new information based on previous entries. This method, which involves brute forcing context into the AI's understanding, could potentially be a valuable asynchronous step in refining the pipeline for more nuanced contextual analysis.
