Hello, I am very new to working with AI. I have been an SWE for 4 years but want to dive deeper into the AI side. I have been trying to learn by building things that can improve my company. It is a niche industry known as small commercial excess and surplus lines of insurance. I didn’t know it existed until I started working there.
The problem I am trying to solve is that we have a decent amount of users who don’t know which insurance product to choose or which classification (“class code” in the dataset) to pick.
The goal of what I want to do is to have a chat prompt that lets them explain what they need insurance for and let it explain what it thinks it should classify it as. I initially tried to use ollama with llama3.1 to do this. Now, as seen in the code I will share, have
been trying to user a BERT transformer to analyze the data and then use GPT-2 via pipeline to present it to the user using natural language.
I am struggling to get accurate results or results at all within my threshold for it to be accurate. I have tried various chunk sizes and overlaps but can’t seem to get it to work. The data is a little sparse, but I am having trouble finding fine-tuning data due to the industry being niche.
Any tips? Thanks in advance!
