高维隐空间中的词元表示常存在冗余,限制计算效率并削弱层间结构一致性。分层隐空间折叠提出一种结构化变换机制,强制学习到的嵌入具有多尺度组织,提升表示紧凑性的同时保留关键上下文区分。该方法通过动态折叠操作迭代调整词元嵌入,影响序列处理任务中的短程与长程依赖。实证评估显示,层间表示方差显著降低,带来更稳定的困惑度分布,并提升文本生成的预测置信度。注意力头利用的结构化重分配使计算资源在深层更高效地分配,层次化修正提升了上下文抽象能力。激活稀疏性模式对比表明,层次调整选择性强化关键路径,减少非必要区域的计算开销。统计分析显示,词元重排序频率出现细微变化,改善了上下文对齐,同时保持句法正确性。分层折叠带来的计算权衡导致每轮训练时间略有增加,但推理效率因结构化表示调整而获益。结果表明,分层隐空间折叠通过优化表示结构与计算效率,显著提升模型性能。
原文摘要 · Abstract (English)
Token representations in high-dimensional latent spaces often exhibit redundancy, limiting computational efficiency and reducing structural coherence across model layers. Hierarchical latent space folding introduces a structured transformation mechanism that enforces a multi-scale organization within learned embeddings, refining representational compactness while preserving essential contextual distinctions. The proposed approach incorporates dynamic folding operations that iteratively adjust token embeddings through structured transformations, influencing both short-range and long-range dependencies in sequential processing tasks. Empirical evaluation demonstrates a reduction in representational variance across layers, contributing to more stable perplexity distributions and enhancing predictive confidence in text generation. The structured redistribution of attention head utilization leads to more efficient allocation of computational resources, particularly in deeper layers, where hierarchical refinements improve contextual abstraction. Comparative analysis of activation sparsity patterns suggests that hierarchical adjustments selectively reinforce critical pathways while reducing computational overhead in non-essential regions of the model. Statistical assessments of token reordering frequencies reveal that hierarchical modifications introduce subtle shifts in sequential dependencies, improving contextual alignment while maintaining syntactic correctness. Computational trade-offs associated with hierarchical folding introduce marginal increases in training time per epoch, yet empirical findings indicate that inference efficiency benefits from the structured representation adjustments. The results highlight the impact of hierarchical latent space folding on optimizing model performance through improved representation structuring and computational efficiency.
