✨✨Quick Read✨✨: Contemporary Model Compression on Large Language Models Inference

✨✨ #QuickRead tl;dr✨✨

✨✨ Research Overview:
This research focuses on model compression techniques aimed at improving the efficiency of large language models (LLMs) during inference. Research explores three primary model compression techniques: #quantization, #knowledge #distillation, and #pruning, and further discusses system-level optimizations like #PagedAttention and #StreamingLLM.

✨✨ #KeyContributions:
- #Quantization, advanced quantization techniques such as AWQ (Activation-Aware Quantization), which selectively reduces precision to optimize model storage and speed. Research introduces a new strategy for activation-aware parameter scaling to minimize quantization loss.

- #KnowledgeDistillation, enables a smaller model (student) to mimic a larger model (teacher). The novel contribution here is #ReverseKnowledgeDistillation, where the teacher evaluates the student’s output, leading to more efficient training compared to traditional methods.

- #Pruning, a focus on #LLMPrunner, a pruning technique that trims unnecessary connections between neurons to reduce model size while maintaining performance. The research emphasizes structural pruning to maintain dependency graphs between neurons, enabling efficient compression.

- #SystematicDesign, System-level optimizations such as #PagedAttention and #StreamingLLM are discussed. These methods improve memory management and reduce computational resources by enhancing how memory caches are handled in LLMs.

✨✨ #Methods:
- Quantization, to reduce the precision of weights during model inference. Techniques such as AWQ focus on activation-aware compression, minimizing the loss by focusing on salient weights.

- Knowledge Distillation, to transfer knowledge from a large model (teacher) to a smaller one (student), with reverse knowledge distillation offering improved efficiency by evaluating student outputs against teacher preferences.

- Pruning, structural pruning trims less important neural network connections. #LLMPrunner uses dependency graphs to evaluate the significance of neuron connections and prunes non-essential links to improve memory efficiency.
