Learn how to streamline table data extraction with Sparrow, Table Transformer, Qwen2 VL, and MLX on the Mac Mini M4 Pro. Simplify your workflow and get accurate results! 

I explain how multipage PDFs are handled in Sparrow to extract structured data in a single call. 

I show how I’m running the Qwen2 72B 4bit model locally on a Mac Mini M4 for Sparrow’s backend. MLX (and MLX-VLM) is the main platform I’m using for local data extraction in Sparrow. 

I'm explaining several hints how to optimize Qwen2 Visual LLM performance for batch processing. 

I explain how Sparrow validates the structured output of visual LLMs to ensure it complies with the JSON schema provided in the query. This process helps prevent errors and hallucinations generated by the LLM.

In this video, I demonstrate how to extract financial market stock data from images using the powerful Vision LLM Qwen2, all within a Gradio interface. This setup allows quick and easy extraction of key stock stats from screenshots and other image-based data sources—perfect for analysts, traders, and finance enthusiasts looking to streamline data processing. Watch to see how this AI tool can simplify your workflow and make stock data analysis faster and more efficient! 

Structured output is all you need. I deployed a Sparrow demo UI with Gradio to demonstrate the output Sparrow can produce by running a JSON schema query. You can see examples for the Bonds table, Lab results, and Bank statement. 

I share performance-boosting tips based on my experience using Qwen2-VL in production. 

Sparrow provides an API for accessing the Sparrow Parse agent, allowing you to run document extraction workflows directly from your existing systems. It helps simplify how data is pulled from documents and integrated into your workflows. 

New Sparrow Agent - Sparrow Parse, works with Qwen2 Vision LLM.

In this video, I demonstrate how to perform document queries using Qwen2-VL-7B. By simplifying field names, we streamline the prompts, making them more efficient and reusable across different documents. This approach is similar to running SQL queries on a database, but tailored for language models like Qwen2-VL-7B, with results returned in JSON format. 

I show how to retrieve structured JSON output from table image using Qwen2-VL-7B. This VLLM performs OCR and data mapping tasks all out of the box, also it can return structured JSON output without use of intermediate frameworks. 

I explain how we extract data with Sparrow Parse, using Table Transformer to identify table area and build table structure to be processed by OCR. Sparrow Parse implements additional logic to clear-up and improve (removing noise, merging columns, adjusting rows) table structure generated by Table Transformer.

Table Transformer model is able to provide table functional analysis. As result we can identify table header area and build cells to enclose each column header. In the next step with crop each cell and read data with OCR. Finally we get structured data for table header column names. 

I show how an open-source transformer model from Microsoft for table detection and structure recognition works. The code is integrated into Sparrow Parse and runs on a local CPU. This approach helps to crop the table area first and then get coordinates for the table cells. Each cell can be cropped and text can be extracted with OCR. This allows retaining the original table structure and reporting the result in JSON or CSV formats. The data extraction part is not in this video; this will be the topic for the next video.

In this video, I demonstrate the latest updates to the Sparrow OCR Service using PaddleOCR. I walk you through the OCR service workflow in Sparrow, showcasing its integration with FastAPI and highlighting the enhanced functionalities brought by the recent PaddleOCR update. Join me to see how you can leverage these powerful tools for efficient OCR processing! 

FastAPI Endpoint for Sparrow LLM Agent. I show how FastAPI endpoint is used in Sparrow to run LLM agent functionality from API client. 

I explain how Sparrow Parse API is integrated into Sparrow for data extraction from PDF documents, such as invoices, receipts, etc. 

LLMs tend to hallucinate and produce incorrect results for table data extraction. For this reason in Sparrow we are using Instructor structured output for LLM to query form data and Sparrow Parse to process tabular data within the same document in combined approach.
