Technical Challenge: Adversarial Multimodal Transfer Learning

In this challenge, we aim to push the limits of multimodal transfer learning on Large Language Models (LLMs). We'll explore a novel scenario where multiple models with different specializations are adversarially evaluated to achieve optimal knowledge transfer.

Background

Recent advancements in multimodal transfer learning have enabled the efficient transfer of knowledge from one domain to another. However, existing approaches often rely on a single, specialized model for each domain. This can lead to suboptimal performance due to the lack of adaptability across different domains.

The Challenge

Develop a hybrid Large Language Model (LLM) that can adapt to multiple domains while preserving its knowledge representation. The model should:

1. Learn from multiple specialized models: Initialize the hybrid model with pre-trained weights from different domain-specialized models (e.g., text classification, sentiment analysis, and machine translation).
2. Adapt to new domains: Train the hybrid model on a new, unseen domain with limited labeled data, using a multi-task learning approach to transfer knowledge from the specialized models.
3. Evaluate on adversarial tasks: Test the hybrid model on a set of synthetic, adversarially generated tasks that target its vulnerabilities in knowledge transfer. These tasks should aim to:

a. Manipulate the model's embeddings to disrupt knowledge representation.
b. Fool the model into misinterpreting domain-specific knowledge.

Evaluation Criteria

• Adversarial robustness: The model's ability to resist attacks that aim to disrupt knowledge transfer.
• Knowledge preservation: The model's ability to preserve existing knowledge when adapting to new domains.
• Efficiency: The model's ability to perform competitively while using significantly fewer parameters than a single, domain-specialized model.

Submission Requirements

To participate, please submit your hybrid LLM implementation along with:

1. Model architecture: A clear description of the model's architecture and design choices.
2. Training procedure: A detailed explanation of your training procedure, including the datasets, hyperparameters, and optimization techniques used.
3. Evaluation results: Results of the model's performance on the adversarial tasks, including accuracy metrics and visualizations of the model's embeddings.

Timeline

• Submission deadline: December 15, 2025.
• Evaluation: The evaluation process will be completed by January 15, 2026.

By accepting this challenge, you agree to share your work under a permissive open-source license (e.g., MIT or Apache). The winner will be selected based on the evaluation criteria and announced by February 1, 2026.
