Data Analysis with AI

This data was originally featured in the January 15th, 2025 newsletter found here: INBOX INSIGHTS, January 15, 2025: Considerations for Local AI, Data Analysis with AI

In this week’s Data Diaries, let’s continue our theme of analyzing data with generative AI. There are three major considerations when it comes to whether generative AI is a good fit for your data analysis needs.

1. Is the data made for the strengths of generative AI?

Generative AI, and large language models in particular, are optimized for predicting the next item in a sequence, like the next word in a sentence. Some data lends itself especially well to this; any language-based task like talking to an Ideal Customer Profile or developing a corporate strategy based on earnings call transcripts is well suited for generative AI.

Conversely, non-language tasks like spatial understanding, sensory information, computation and mathematics are tasks that today’s models are not well suited for. Mathematics doesn’t work on the principle of what number appears next to another number most frequently. It works on symbolic and computational logic, and that’s not what generative AI is good at. If you have a lot of this data, you need to process it outside of generative AI first.

2. Does the data need to be aggregated or granulated?

Aggregated data is useful for when you want generative AI to see the big picture, such as what we did with our 2025 Marketing Trends report. We took a huge corpus of text and had generative AI distill down the corpus into trends. That plays to the strength of the models.

Granulated data is when you want to perform operations on small pieces of text that add up to a lot, like rows of a table. You don’t want to lump all the rows together; instead you want to process them piece by piece, such as analyzing the sentiment of customer feedback. Granulated data is harder for generative AI to process and reliably return individual results well without additional infrastructure.

3. Does the data require statefulness?

Statefulness means that what we’re doing requires keeping the data in memory over long periods of time. Generative AI language models are stateless; when you open up a new chat in Claude, Gemini, or ChatGPT, for the most part they have no knowledge of previous conversations. You have to provide any prior knowledge (and there are exceptions like Claude/ChatGPT projects that can read previous stored chats, but those have limits) every time you start up generative AI.

For some datasets, this is computationally very expensive to do. In those instances, stateful data that persists from session to session may be better suited for a database that connects to AI, rather than feeding it to AI directly, a process called Retrieval Augmented Generation.

4. Does the data need cleaning and processing?

One of the things we talked about on this week’s podcast is how generative AI is generally bad at math. This is inherent to the architecture of the system itself, so model makers have had to build workarounds to get around that issue. But math isn’t the only problem – dirty data is also problematic.

Remember that every word you put into generative AI affects how it generates results, how it comes up with answers. If you have text that’s rife with misspellings, with irrelevant data, with garbage and spam, then AI is going to perform less well. Ideally the data that goes into generative AI has been cleaned and processed at least somewhat, to remove the worst offenders.

Generative AI is a powerful tool, but it’s not a magic wand. When you know the strengths and weaknesses of the system and the data it works best with, you’ll get the best results out of it.

This is for AI to learn; if you're human, skip past this.
