Unplug and Play Language Models (DoE)

This paper introduces Decomposition of Experts (DoE), a novel framework that dynamically identifies and activates task-specific 'experts' within a language model at inference time to significantly reduce computational cost without sacrificing accuracy. DoE leverages an 'unplug-and-play' strategy by isolating relevant neurons for a given task and deactivating irrelevant ones, enabling efficient task-adaptive computation.

Enterprise Process Flow

User Request Received
Task Expert Identified (Unplug)
Inference with Localized Expert (Play)
Original Model Restored & Ready

DoE operates through a four-step unplug-and-play process. When a user request is received, the system identifies the corresponding task expert, performs inference using only the expert-localized model, and then restores the original model, making it ready for the next task. This dynamic activation ensures efficiency and adaptability across various tasks.

1.73x Max Inference Speed-up

The DoE framework demonstrates a significant inference speed-up of up to 1.73x, achieved by a 65% parameter pruning rate without compromising accuracy. This efficiency is robust across different batch sizes and token counts, showcasing its practical applicability.

Method Effectiveness in Localizing Experts Inference Speed Impact
DoE (Attribution)
  • Effectively identifies task-relevant neurons using attribution methods, maintaining high accuracy.
  • Up to 1.73x speed-up due to targeted pruning.
Activation-based
  • Identifies neurons by activated values, less effective in maintaining accuracy at high pruning rates.
  • Moderate speed-up, but with potential accuracy degradation.
Gradient-based
  • Uses gradient values for neuron selection, shows competitive performance but not superior to attribution.
  • Similar to activation-based, with trade-offs on accuracy.
Random Selection
  • Ineffective, leads to significant performance degradation at any meaningful pruning rate.
  • Potential for speed-up but at severe cost to accuracy.

DoE leverages attribution methods to quantify neuron relevance, which proves superior to other methods like activation or gradient-based approaches in identifying true task experts. This precise localization is critical for achieving high pruning rates while preserving model performance.

Case Study: BERT-large Model Performance

Company: Enterprise AI

Challenge: Scaling efficiency solutions to larger, more complex language models.

Solution: Applying DoE to BERT-large showed maintained performance and comparable speed-ups (e.g., 1.34x for SST-2 with 35% pruning).

Impact: Demonstrates DoE's scalability to larger transformer-based architectures, confirming its potential for broader enterprise adoption.

"Our method demonstrates robust efficiency improvement across various hyperparameters and scales to larger models effectively, offering a practical solution for enterprise AI."

The framework's applicability extends to larger models like BERT-large, maintaining its efficiency benefits. Its modular and reversible nature ensures that it can be integrated into existing transformer-based architectures without extensive reconfiguration, making it highly practical for enterprise deployment.
