Researchers have developed a method to better understand and manage error propagation in compressed transformer models. By measuring the ratio of output to input error (rho) at each layer, they found that errors accumulate predictably, explaining why compressing earlier layers is more detrimental. This analysis also revealed significant variability in component sensitivity within layers, suggesting that importance scores do not transfer well across different model architectures. The study proposes a training-free approach using these compression profiles to guide decisions on where to compress within layers and which layers to remove entirely, improving efficiency without substantial performance loss.
