The paper introduces REP‑LIE, a resource‑efficient pruning method for Transformer models that estimates weight importance using gradients from LoRA low‑rank matrices, avoiding full gradient computation. It incorporates a stability score to iteratively prune unimportant parameters and then fine‑tunes the pruned model with lightweight updates, eliminating the need for full‑parameter optimization. Experiments on medium‑scale encoders and large‑scale generative models such as LLaMA‑7B and Mistral‑7B show that REP‑LIE achieves competitive performance compared to existing pruning approaches.

The paper presents a retraining‑free technique that transforms pre‑trained transformers into elastic models capable of adapting to any computational budget on the fly. By jointly ranking every MLP neuron and attention head on a common scale and applying soft pruning across multiple sparsity targets, the method achieves smooth performance degradation up to 60% sparsity while outperforming one‑shot baselines. Experiments on 27 vision and text transformer encoders show significant parameter reductions with minimal accuracy loss and notable throughput and latency gains on GPUs, all produced in minutes.

MoARa introduces a module-aware rank allocation strategy and a block-wise magnitude-direction decomposition to improve low-rank gradient projection for large language model pre‑training. By profiling Transformer modules and tailoring projection ranks, it reduces the number of steps and wall‑clock time needed to reach target perplexity. Experiments on Llama, Qwen, and DeepSeek models show up to 41.7% fewer steps and 37.1% less training time with minimal memory overhead.

Deploying Large Language Models (LLMs) in practice incurs substantial memory and computational costs. Post-training pruning (PTP) is an effective approach to reducing these costs by removing weights without additional training.
