Artificial Intelligence Intern

From Aug 2024 To Jan 2025

Tetra Pak © is a Swedish multinational company specializing in food packaging and processing solutions. Founded in 1951 by Dr. Ruben Rausing and Swedish engineer Erik Wallenberg.

Tetra Pak operates in over 160 countries and employs more than 25,000 people worldwide. The company’s mission is to make food safe and available everywhere, driven by a commitment to sustainability and innovation. Tetra Pak’s product portfolio includes packaging, filling machines, and processing equipment for dairy, beverages, cheese, ice cream, and prepared foods.

During my internship as an AI Engineer in the D&T department, I focused on adapting Visual Language Models for domain-specific data to improve the efficiency of the company’s quality control process by automating the test environment. I researched and implemented state-of-the-art models, such as CLIP and SigLip, and devised ways to adapt them to Tetra Pak’s specific use case.

At the end of my internship, I presented my findings and recommendations to the team, highlighting the potential benefits of integrating Visual Language Models into the company’s quality control process. My work was well-received, and the team is now considering implementing my suggestions in future projects.

Throughout the internship, I faced several challenges, from data preprocessing to model fine-tuning. I manually annotated a dataset of a thousand image-text pairs, which helped me understand the importance of data quality in machine learning projects. I also learned how to fine-tune models using transfer learning techniques, improving their performance on domain-specific data.

The approach was successful, achieving an accuracy of 85% on the test set for classifying deviations from nominal conditions, a significant improvement over the baseline model.
