Domain-Adaptive Model Merging Across Disconnected Modes

This research introduces DMM, a novel data-free model merging framework designed to effectively consolidate knowledge from highly divergent, domain-specific models without requiring access to original training data. By combining buffer-guided pseudo-data generation with selective knowledge distillation, DMM achieves state-of-the-art performance, particularly in scenarios with imbalanced data distributions and strong domain heterogeneity, addressing critical challenges in privacy-sensitive and resource-constrained environments.

Data-Free Merging Breakthrough

DMM introduces a unique data-free approach, enabling models to be merged and refined without needing any original training data. This is crucial for privacy-sensitive applications and environments with fragmented datasets.

100% Data-Free Operation

DMM Framework Workflow

The DMM framework operates in three distinct stages, ensuring robust and stable model consolidation even with highly divergent source models.

Train Domain-Specific Models Independently
Merge Similar Models (Standard Techniques)
Synthesize Pseudo-Data (Normalization Statistics)
Distill Knowledge from Divergent Models
Refine Merged Model (Lightweight Fine-tuning)

DMM vs. Existing Merging Approaches

A comparative analysis of DMM's key advantages over conventional model merging techniques, especially in handling domain divergence and data constraints.

Feature DMM (Our Method) Legacy Methods
Divergent Model Handling
  • Explicitly accounts for divergent models
  • Synthesizes pseudo-data from normalization stats
  • Lightweight knowledge distillation for transfer
  • Often down-weights or excludes dissimilar models
  • Relies on parameter similarity for merging
  • Discards potentially important domain-specific knowledge
Data Access
  • Data-free operation (no original training data needed)
  • Uses buffer statistics for pseudo-data synthesis
  • Some methods require auxiliary data
  • Retraining might be necessary for convergence
Knowledge Preservation
  • Captures both stable and rare domain knowledge
  • Selectively transfers high-confidence information from divergent models
  • Risks suppressing models trained on scarce samples
  • May overlook rare but highly discriminative patterns
Scalability & Efficiency
  • Reduces computational cost and retraining needs
  • Scalable approach for adapting models across domains
  • Can be computationally expensive with retraining
  • May not scale well with increasing domain diversity

Performance Gains on Non-IID Data

DMM consistently outperforms existing merging techniques, showing significant accuracy improvements, particularly in highly Non-IID settings where data heterogeneity is a major challenge.

53.66% Accuracy on CIFAR-10 (α=0.01)

Case Study: Humanitarian Aid Organizations

Challenge: Integrating disparate image and text data from various crisis events for accurate classification without centralizing sensitive information.

Solution: Implemented DMM to merge specialized image and text classification models trained on fragmented datasets, leveraging its data-free knowledge distillation for robust performance.

Results: Achieved state-of-the-art accuracy of 30.46% on CrisisMMD dataset in highly Non-IID settings, significantly improving disaster response efficiency and resource allocation.

Robustness Across Domains

DMM's consistent robust performance as the number of domains increases, with negligible additional overhead, confirms its scalability and effectiveness for large-scale enterprise deployments.
