Course Description

Unlock the power of unstructured data and elevate your AI-driven applications with this comprehensive course on transforming unstructured data into actionable insights using advanced techniques. Whether you’re a developer, data scientist, or AI enthusiast, this course will equip you with the skills to extract, process, and normalize content from diverse document formats—including PDFs, PowerPoints, Word files, HTML pages, tables, and images—making your data-ready for sophisticated RAG systems and Large Language Models (LLMs).

In this hands-on course, you'll delve deep into the Unstructured Framework, a powerful tool for managing and normalizing unstructured data. I'd like you to learn how to enrich your documents with metadata, apply advanced chunking techniques, and use hybrid search methods to enhance your data retrieval and generation processes. With a focus on real-world applications, you’ll gain practical experience in preprocessing documents using vision models like ViT, extracting valuable information through table transformers, and seamlessly integrating these components into your RAG-powered applications.

What You’ll Learn:

  • Master the Unstructured Framework: Understand how to leverage the Unstructured Framework for handling and normalizing diverse data types, optimizing them for use in RAG systems and LLMs.

  • Advanced Metadata Extraction: Learn to enrich your documents with comprehensive metadata, improving search accuracy and relevance in AI-driven applications.

  • Implement Cutting-Edge Chunking Techniques: Apply advanced chunking methods to manage and process large datasets, ensuring efficient data handling and retrieval.

  • Harness Hybrid Search Capabilities: Explore hybrid search techniques that combine metadata and content-based retrieval, boosting the performance of your query engines.

  • Document Image Analysis with ViT: Utilize vision models like ViT and table transformers to analyze and preprocess document images, enhancing your ability to extract and utilize unstructured data.

Why This Course?

This course is designed for professionals who want to go beyond basic data processing and dive into advanced techniques for managing unstructured data in RAG systems. Through a series of practical projects, you’ll gain the expertise to build and deploy robust, scalable data engines that can handle complex queries and generate contextually relevant responses.

Very good staff. Please continuously update the tutorials to keep pace with the times. Thank you.

By Muhammad Riaz on 6/16/2025

Good to know basics of chunking with Unstructured Framework only. If you are looking for free open source chunking frameworks, this is not the course you are looking for. Course is surrounded around Unstructured Framework for chunking pdf, html, and documents.

By Kannan Sundaram on 5/8/2025

Very very good course. Just the right duration. I have learnt a lot in this class.

By Aaron Otto on 12/30/2024

So there are a couple issues with this course- if you are looking to learn how to pre-prep files for LLM ingestion, look elsewhere. Unless you can get your company to license software or they already have 'unstructured' framework for enterprise. Issue most people looking to do this work will run into not being able to go to unstructured.io and use their api. This problem is real. It would be better service to take a class on doc ai which can be accessed more widely and less costly. Or even better create all these functions put them on your repo sans api call. That would be truly helpful. PDFs are an industry bane. Teach folks how to solve that nut without pay for api- you will be a king!

By Nada Makram on 11/28/2024

I didn't like that you are using an enterprise library, unstructured, with limited capabilities in the open source version, code can't be recognized as a practice for the theoretical part! could have been better but you are GOOD instructor.

By Gerhard Ritzmann on 11/26/2024

Paulo teach step by step and explains the content very good. He has a good voice and there are some hands on programs. My wish for the future is, that one of this his is developing one program to a production use.

By Jeffrey James on 11/18/2024

Always quality education from this guy. I love his hands on examples. It would be awesome if he did something on Flowise.

By Diego Robayo on 11/10/2024

Totally recommended if you are specifically looking to understand normalizing data from different document formats for llm consumption. The course goes to the point. The instructor is very knowledgeable, and has a soothing voice. Also, very nice visualizations.

By Jose Paulino on 10/14/2024

Yes, it's an excellent way to get started, It provides enough theory with simple to understand code sample which build toward more complex use case. After this course you feel a more confident to then go ahead an read and play with online tutorial because this course provide good foundation. My only question is when we use pay framework like OpenAI and Unstructured are this the common enterprise practices. Meaning it's it cost effective to use these platforms as explained here or should this course use framework like Hugging face and open source models.

By Szkolenia Systemics on 9/22/2024

Thank you very much for this course. I found the instructor to be knowledgeable and experienced, while the content is organized and well given. As for me, the examples are a little too simple, but for someone who wants to form his knowledge - sufficient. If someone wants to write his own RAG I recommend not only this course, but others treating vectorization or writing RAG. I look forward to more courses.
