What if, in your next adventure, you were surrounded by people who, like you, look for an unlimited playground to explore, share, and test, would you care to hear more? You've opened the right door! As an R&D team, making sure your ideas are heard and encouraged is what we strive to do!
The goal of this internship is to explore approaches for automatically generating new markup templates that could lead to more effective layouts. In particular, we aim to leverage Large Language Models (LLMs) to generate valid and diverse templates based on existing examples.
A key advantage of LLMs is their ability to be fine-tuned and aligned with performance objectives by leveraging the right data. This enables us to pursue Generative Creative Optimization (GCO)—where a generative model, conditioned on the context, will likely produce, high-performing creatives. By integrating LLMs into this process, we can move beyond manual template design and unlock a broader, more optimised space of ad layouts.
Projected outline of the internship
This internship focuses on fine-tuning Large Language Models (LLMs) to generate high-performing ad layouts. The project will begin with a research phase, where the intern will review existing methods for LLM alignment, including RLHF, Direct Preference Optimization (DPO), and RL with constraints. During this phase, they will analyse the problem, study the dataset in hand, and define evaluation benchmarks to assess layout performance.
Once the research foundation is set, the intern will experiment with different training techniques, prompt designs, and model architectures to improve layout generation. The goal is to identify the best alignment approach based on business performance metrics and validate its effectiveness through controlled experiments.
The next stage will involve implementing and testing the model, comparing its outputs against existing manual and automated methods. The intern will refine the approach based on quantitative and qualitative evaluations, ensuring the generated layouts align with business goals.
By the end of the internship, the findings will be synthesized into a research paper for potential submission to a workshop or conference. If the approach proves successful, there may be an opportunity to explore its integration into production systems.
