One-for-All Model Initialization with Frequency-Domain Knowledge

arXiv:2603.07523v2 Announce Type: replace Abstract: Transferring knowledge by fine-tuning large-scale pre-trained networks has become a standard paradigm for downstream tasks, yet the knowledge of a pre-trained model is tightly coupled with monolithic architecture, which restricts flexible reuse across models of varying scales. In response to this challenge, recent approaches typically resort to either parameter selection, which fails to capture the interdependent structure of this knowledge, or parameter prediction using generative models that depend on impractical access to large network col

Why this matters
Why now

The proliferation of various large-scale pre-trained models necessitates more flexible and efficient knowledge transfer methods beyond monolithic fine-tuning, driving research into architecture-agnostic initialization.

Why it’s important

This research addresses a fundamental limitation in current AI development by allowing more flexible reuse of pre-trained knowledge across models of varying scales, potentially accelerating innovation and reducing computational costs.

What changes

The ability to transfer knowledge more effectively across different model architectures could lead to a decoupling of pre-trained knowledge from specific monolithic models, fostering more adaptable and efficient AI development.

Winners
  • · AI researchers and developers
  • · Companies using diverse AI model architectures
  • · Cloud AI providers
Losers
  • · Developers solely reliant on rigid fine-tuning paradigms
  • · Companies with highly specialized, non-transferable AI models
Second-order effects
Direct

More efficient and versatile deployment of AI models for downstream tasks, reducing the need for extensive re-training.

Second

Accelerated development cycles for new AI applications as knowledge transfer becomes less architecture-dependent.

Third

Lower barriers to entry for developing competitive AI models, potentially increasing market competition and democratizing advanced AI capabilities.
