Amazon ML Hackathon 2024

Team: ML Mavericks

Overview

In the 2024 Amazon ML Hackathon, our team achieved an impressive rank of 64th out of over 75,000 participants from across India. Our project focused on Feature Extraction from Images, utilizing advanced machine learning techniques to extract critical product information directly from images. This capability is essential in fields such as healthcare and e-commerce.

Project Description

Our solution leverages the MiniCPM-Llama3-V-2.5 model, a cutting-edge vision-language model that integrates visual processing capabilities with natural language understanding. The system is designed to efficiently extract entity values, such as weight and dimensions, from product images.

Key Features

  • Distributed Inference: We conducted inference using over 15 GPUs, optimizing processing speed and scalability.
  • Kaggle GPU Support: We are grateful to Kaggle for their generous GPU support, which was vital for our project's success.
  • Multilingual Support: The model effectively processes both English and German texts.

Code Structure

The main code folder contains two Jupyter Notebooks:

  1. Inference Notebook: This notebook contains the logic for performing inference, including the starting and ending index for processing.
  2. Post-processing Notebook: This notebook is used for refining the model's output and preparing it for submission.

Methodology

  1. Data Preparation:
    • Image normalization and resizing.
    • Text extraction from image metadata.
  2. Model Implementation:
    • Used the MiniCPM-Llama3-V-2.5 model for extracting product attributes.
    • Implemented batch processing for efficient resource utilization.
  3. Post-processing Pipeline:
    • Extracted numerical values and standardized units.
    • Handled edge cases and ensured precision.

Results

  • Processing Speed: Average time per image ranged from 2 to 3.5 seconds.
  • Scalability: The distributed processing approach allowed efficient handling of large datasets.

Challenges and Limitations

  • Resource Intensity: The model's size may limit real-time application viability.
  • GPU Availability: Dependency on Kaggle's resources could be a challenge for sustained use.

Conclusion

Our implementation of the MiniCPM-Llama3-V-2.5 model, combined with a robust post-processing pipeline, has shown exceptional performance in extracting product attributes from images. This solution is poised to enhance automation in e-commerce and inventory management.
