这期视频带大家完整串讲 DeepSeek Engram 这篇论文,以及它背后的两条技术支线:Memory Network 和 N-gram。理解了这些背景工作,再看 Engram 就会发现水到渠成。 📚 本期串讲的论文/背景: 【Memory 支线】 • Facebook 2019 - Language Models as Knowledge Bases • Google 2020 - T5 作为 Knowledge Base • 2021 - Transformer FFN 层是 Key-Value Memory • Microsoft 2022 - Knowledge Neurons • Facebook 2019 - Product Key Memory (PKM) • Meta - Memory Layer 扩展到 128B 参数 • DeepMind 2022 - Retrieval-Enhanced Transformer (RETRO) • Google 2023 - External Memory 提升模型能力 【N-gram 支线】 • 传统 N-gram 语言模型基础 • Google 2022 - N-Grammer:用 N-gram Embedding 增强 Transformer • Google 2025 - Scaling Embedding Layer 【DeepSeek Engram】 • 核心思想:用 N-gram Embedding + Hash 查表实现高效知识检索 • 技术要点:Sparsity、Gating 机制、Memory Hierarchy • 与 MoE 的关系:Engram 是 MoE 的补充 🎯 核心观点: 1. Transformer 的 FFN 层本质是一个 Key-Value Memory 2. Sparsity 是打破「不可能三角」的关键(Performance / Compute / Model Size) 3. 通过 Hash 查表实现 O(1) 复杂度的 N-gram 检索 4. Engram 让模型不用「计算」就能「记住」常识知识 5. DeepSeek 的工作是前人研究的集大成者 #DeepSeek #Engram #LLM #Transformer #Memory #Ngram #AI #论文解读 #深度学习 Chapters: 0:00 Overview 10:08 Transformer 中的 Memory 机制 31:33 N-gram 方法回顾 48:32 DeepSeek Engram 方法详解 55:40 实验结果与总结 #DeepSeek #Engram #LLM #Transformer #AI #深度学习 #论文解读 追踪AI每日AI新闻和Paper的工具: https://www.aidaily.win 学习和刷课的工具: https://www.studies.win
