Finding the right embedding model for your specific data can often feel like guesswork, but it doesn't have to be. While generic benchmarks provide a baseline, they rarely reflect how a model will perform on your unique datasets and niche terminology.
We just posted a course on the freeCodeCamp.org YouTube channel that offers a comprehensive, beginner-friendly roadmap to mastering the art of custom benchmarking. By moving beyond standard metrics, you will learn how to leverage Vision Language Models for precise text extraction, use LLMs to generate synthetic evaluation data, and apply rigorous statistical tests to determine which model truly delivers the best results for your machine.
In this course, you will learn how to:
Overcome the limitations of standard Python libraries for PDF text extraction by using Vision Language Models (VLMs).
Segment extracted text into context-preserving chunks.
Generate evaluation questions for each chunk using Large Language Models (LLMs).
Create vector representations of your data using both open-source and proprietary embedding models.
Deploy local models in GGUF format on your own machine using llama.cpp.
Benchmark different embedding models using various metrics and statistical tests with the ranx library.
Visualize vector representations through plotting to see how clusters are formed.
Interpret statistical results, including understanding the significance of p-values.
And much more!
