![]() ![]() ![]() Why would LLMs do well on Tabular Data at all?Īs a thought exercise, and to form some intuition for why an LLM should be able to make predictions on tabular data, let’s take a look at an example from the original TabLLM paper on predicting the income of an individual from their age, education and gain:Įxample from the TabLLM paper on predicting the income of an individual using tabular data. In this post, we will demystify key concepts from the paper, provide a step-by-step guide to reproducing the study's results using Predibase, and give our insights on the practicality and suitability of LLMs for tabular data tasks. While LLMs provide many advantages for tabular data, especially in low-data scenarios, they come with challenges as well. The paper established a method for zero-shot and few-shot tabular classification by serializing the data into text, combining each sample with a prompting question, and feeding the result into an LLM. "TabLLM: Few-shot Classification of Tabular Data with Large Language Models" (Hegselmann et al., 2023) attempted to evaluate this possibility by testing the application of LLMs across multiple tabular datasets. Their success on various tasks suggests the possibility that the inherent knowledge in an LLM could be useful also for understanding tabular data, if formatted adequately Large Language Models (LLMs), meanwhile, are proving increasingly capable at tackling complex generative natural language tasks without having been explicitly trained to solve them. While deep learning models like TabNet and TabTransformer have been developed for tabular data, they do not consistently stand above GBMs in cost or quality. Businesses meticulously organize data like customer information, sales transactions, operations logs, and financial records into tables and spreadsheets. Tabular data remains a mainstay across industries, ranging from healthcare and climate, to finance. In today's LLM world, the question remains: where does tabular data fit in? In this detailed analysis, we expand upon the TabLLM paper to better understand when and why you should use LLMs for tabular data tasks. ![]()
