Researchers from ISTA Austria and Neural Magic Introduce QMoE: A Revolutionary Compression Framework for Efficient Execution of Trillion-Parameter Language Models

The Mixture of Experts (MoE) architecture combines multiple subnetworks to handle complex data, but it can be computationally expensive. Researchers have introduced QMoE, a framework that compresses trillion-parameter MoEs to less than 1 bit per parameter, making them more efficient to run. This is achieved through data-dependent quantization methods and can be processed in less than a day on a single GPU. This research focuses on the compression of pretrained base models and has future plans to fine-tune compressed models for specialized tasks.

Mixture of Experts (MoE): Practical Solutions for Complex Data

Introduction

A Mixture of Experts (MoE) is a neural network model that combines the output of multiple expert subnetworks to make predictions or decisions. It is especially useful for handling complex and diverse data that requires specialized models. MoE models are robust to outliers or noise in the data because they can learn to ignore experts that perform poorly on certain inputs.

Computational Cost

The computational cost of a MoE architecture can vary depending on the model’s design, task complexity, and hardware used. MoE architectures can be more expensive than traditional neural networks, especially with many experts and complex gating mechanisms. For example, the Switch Transformer-c2048 model has 1.6 trillion parameters, requiring 3.2 TB of memory to run efficiently.

Solution: QMoE

Researchers have introduced a solution called QMoE to address the memory problem. QMoE is a scalable algorithm that compresses trillion-parameter MoEs to less than 1 bit per parameter. For instance, the Switch Transformer-c2048 model’s 1.6 trillion parameters can be compressed to less than 160 GB, processed in less than a day on a single GPU. This is achieved through affordable retraining-free compression techniques.

Data-Dependent Quantization

Quantization is used to reduce the model size and weights to lower numerical precision. However, some MoEs are so large that higher reduction rates are required. Data-dependent quantization methods train the model with quantized weights and activations, allowing it to adapt to lower-precision representations. Popular frameworks like TensorFlow, PyTorch, and TensorRT provide support for quantization-aware training and calibration.

Future Work

Researchers are focusing on compressing the pretrained base model and plan to include finetuning for specialized downstream tasks. This ongoing work aims to improve the efficiency of MoE compression.
