Conventional Model Compression for BERT
Standard model compression techniques can be effectively used to create more compact versions of BERT. Two primary methods are pruning and quantization. Pruning involves the removal of components from the Transformer's encoding network, such as entire layers, a fraction of the model's parameters, or specific attention heads. Notably, pruning attention heads can enhance inference speed with minimal impact on performance. Quantization, another key technique, reduces model size by converting its parameters to low-precision numerical formats. Although a general method not exclusive to BERT, quantization is particularly well-suited for large Transformer-based models.

Pruning for BERT Compression
Quantization for BERT Compression
A development team is working to optimize a large, pre-trained language model for a real-time translation application. The model's current inference speed is too slow. They are considering two strategies: (1) removing a specific number of attention heads from each layer, or (2) representing all model parameters with lower-precision numbers. Which statement best distinguishes the primary impact of these two compression techniques in this context?
BERT Compression Strategy for Mobile Deployment
An engineering team needs to make a large language model more efficient for deployment. They are considering two distinct compression methods. Match each method with its corresponding description.
