Features adaptive memory, self-learning intelligence, RAG integration, and native Claude Code / Codex / Hermes and many more Integrated项目地址: https://gitcode.com/GitHub_Trending/cl/ruflo导读本文围绕 ruflo 仓库中 Claude Code 数据域 Agent 定义文件>// 1. Search for similar past model training const similarModels await reasoningBank.searchPatterns({ task: ML training: modelType, k: 5, minReward: 0.8 }); if (similarModels.length 0) { console.log( Learning from past model training:); similarModels.forEach(pattern { console.log(- ${pattern.task}: ${pattern.reward} performance); console.log( Best hyperparameters: ${pattern.output}); console.log( Critique: ${pattern.critique}); }); // Extract best hyperparameters const bestHyperparameters similarModels .filter(p p.reward 0.85) .map(p extractHyperparameters(p.output)); } // 2. Learn from past training failures const failures await reasoningBank.searchPatterns({ task: ML training, onlyFailures: true, k: 3 }); if (failures.length 0) { console.log(⚠️ Avoiding past training mistakes:); failures.forEach(pattern { console.log(- ${pattern.critique}); }); }源码佐证ReasoningBank 的真实实现位于 hooks/src/reasoningbank/index.ts。storePattern约 L310会先用嵌入服务对策略文本做向量化再通过searchPatterns做去重检测当命中相似度超过dedupThreshold时走更新已有模式路径递增usageCount、刷新updatedAt、重算quality并触发晋升检查否则新建GuidancePatternquality初始 0.5并写入短期模式缓存与 HNSW 索引searchPatterns约 L366优先走 HNSW 索引注释标注 150x 加速失败时回退到bruteForceSearch余弦相似度排序取 top-k。这正是检索相似训练经验的底层引擎。2.2 训练中GNN 增强的超参数搜索当超参数之间存在耦合关系如学习率影响 batch size、batch size 影响所需 epoch 数时用图结构表达依赖交给图神经网络搜索更优组合// Use GNN to explore hyperparameter space (12.4% better) const graphContext { nodes: [lr1, lr2, batchSize1, batchSize2, epochs1, epochs2], edges: [[0, 2], [0, 4], [1, 3], [1, 5]], // Hyperparameter relationships edgeWeights: [0.9, 0.8, 0.85, 0.75], nodeLabels: [LR:0.001, LR:0.01, Batch:32, Batch:64, Epochs:50, Epochs:100] }; const optimalParams await agentDB.gnnEnhancedSearch( performanceEmbedding, { k: 5, graphContext, gnnLayers: 3 } ); console.log(Found optimal hyperparameters with ${optimalParams.improvementPercent}% improvement);注12.4% better为定义文档中的标注值属于参考收益从源码结构看GNN 能力确有落地支撑——commands/ruvector/init.ts 会创建gnn_edges表并为其建立source_id/target_id索引memory-bridge.ts 中注册了gnnServiceruvector/README.md 亦提供hooks_gnn_info能力查询。2.3 大数据集Flash Attention 加速当样本数超过 10 万时切换到 Flash Attention 处理查询向量与数据集向量的相似度计算// Process large datasets 4-7x faster with Flash Attention if (datasetSize 100000) { const result await agentDB.flashAttention( queryEmbedding, datasetEmbeddings, datasetEmbeddings ); console.log(Processed ${datasetSize} samples in ${result.executionTimeMs}ms); console.log(Memory saved: ~50%); }源码佐证Flash Attention 的实现位于 neural/src/flash-attention.ts。该类采用分块tiling策略将显存/内存复杂度从 O(N²) 降到 O(N)blockSize默认 32面向 CPU L1 cache核心技巧包括Online softmax逐块维护maxScores与sumExp运行统计块间用指数校正因子Math.exp(oldMax - newMax)缩放历史输出兼顾数值稳定性与增量计算对应源码onlineSoftmaxAccumulateCPU 优化路径useCPUOptimizations默认开启两阶段筛选先用 1/4 维度的partialDotProduct快速筛候选再做全维度打分、Top-K 稀疏注意力topK max(16, min(96, ceil(numK * 0.12)))、8 路循环展开点积、预分配Float32Array/Float64Array缓冲区避免 GC 压力内置基准benchmark()对比朴素 O(N²) 注意力与 CPU 优化路径输出speedup、memoryReduction等指标。源码头部注释的目标区间为 CPU 上相对朴素注意力的 2–5x 加速CLI 帮助文本标注 2.49x–7.47x内存约省 ~50%。2.4 训练后回写学习模式形成正反馈闭环训练完成并完成评估后把任务 输入 输出 奖励 成败整体存入模式库// Store successful training pattern const modelPerformance evaluateModel(trainedModel); const hyperparameters extractHyperparameters(config); await reasoningBank.storePattern({ sessionId: ml-dev-${Date.now()}, task: ML training: ${modelType}, input: { datasetSize, features: featureCount, hyperparameters }, output: { model: modelType, performance: modelPerformance, bestParams: hyperparameters, trainingTime: trainingTime }, reward: modelPerformance.accuracy || modelPerformance.f1, success: modelPerformance.accuracy 0.8, critique: Trained ${modelType} with ${modelPerformance.accuracy} accuracy, tokensUsed: countTokens(code), latencyMs: trainingTime });奖励信号设计要点reward取 accuracy 或 F1 这类归一化指标success以 accuracy 0.8 为阈值critique保存人类可读的经验总结。下一次同类任务执行第 2.1 节检索时这些数据就是历史经验的来源——这正是data-ml-model.md中v2_capabilities: self_learning的具体实现闭环。三、领域级优化三类专项能力详解3.1 ReasoningBank 用于模型训练模式管理存储成功的超参数配置以 RandomForest 为例// Store successful hyperparameter configurations await reasoningBank.storePattern({ task: Classification model training, output: { algorithm: RandomForest, hyperparameters: { n_estimators: 100, max_depth: 10, min_samples_split: 5 }, performance: { accuracy: 0.92, f1: 0.91, recall: 0.89 } }, reward: 0.92, success: true, critique: Excellent performance with balanced hyperparameters }); // Retrieve best configurations const bestConfigs await reasoningBank.searchPatterns({ task: Classification model training, k: 3, minReward: 0.85 });这里把「算法 超参 指标」结构化存入reward直接取 accuracy 0.92检索时用minReward过滤低质量配置确保只复用被验证过的高分方案。3.2 GNN 用于超参数依赖建模当超参数之间存在因果/耦合关系时把它们建成图// Build hyperparameter dependency graph const paramGraph { nodes: [ { name: learning_rate, value: 0.001 }, { name: batch_size, value: 32 }, { name: epochs, value: 50 }, { name: dropout, value: 0.2 } ], edges: [ [0, 1], // lr affects batch_size choice [0, 2], // lr affects epochs needed [1, 2] // batch_size affects epochs ] }; // GNN-enhanced hyperparameter search const optimalConfig await agentDB.gnnEnhancedSearch( performanceTarget, { k: 10, graphContext: paramGraph, gnnLayers: 3 } );边的语义即领域知识例如learning_rate与epochs的耦合学习率过大时往往需要更少 epoch、batch_size与epochs的权衡。GNN 通过多层消息传递gnnLayers: 3在参数图上聚合邻域信息从而比独立采样网格更高效地逼近最优组合。3.3 Flash Attention 用于百万级样本// Fast processing for large training datasets const trainingData loadLargeDataset(); // 1M samples if (trainingData.length 100000) { console.log(Using Flash Attention for large dataset processing...); const result await agentDB.flashAttention( queryVectors, trainingVectors, trainingVectors ); console.log(Processed ${trainingData.length} samples); console.log(Time: ${result.executionTimeMs}ms (2.49x-7.47x faster)); console.log(Memory: ~50% reduction); }适用场景数据点之间的相似度矩阵计算如原型选择、检索增强训练、主动学习采样。阈值 10 万样本是文档建议的启用开关真实实现中FlashAttention.attention()还会根据规模自动路由——useCPUOptimizations开启时走 CPU 优化路径否则当numQueries * numKeys 1024时走分块路径小规模则回退朴素计算见 flash-attention.ts。四、前后置钩子把自学习协议接入 CLI 运行时定义文件hooks段把第 2 节的协议落地为可执行 shell 钩子在pre_execution/post_execution/on_error三个时机调用claude-flowCLI 的模式管理能力。4.1 执行前pre_execution环境探测 经验加载echo ML Model Developer initializing... echo Checking for datasets... find . -name *.csv -o -name *.parquet | grep -E (data|dataset) | head -5 echo Checking ML libraries... python -c import sklearn, pandas, numpy;
