WSaiOS Cognitive Learning Engine学习引擎源码实现

44.5 Rule Evolution规则进化模块源码实现

在44.4节中,我们完成了:

  • Knowledge Learning;
  • Pattern → Knowledge转换;
  • Cognitive Knowledge Network;
  • Knowledge Consolidation。

此时Learning Engine已经具备:

Experience

↓

Pattern

↓

Knowledge

但是:

知识本身不能直接驱动系统行为。

WSaiOS需要进一步将知识转换为:

可执行、可判断、可更新的认知规则。

因此设计:

Rule Evolution Module

规则进化模块


44.5.1 Rule Evolution定位

Rule Evolution负责:

将:

Knowledge

↓

Rule

↓

Decision Logic

↓

Execution Behavior

例如:

Knowledge:

结构化输出流程

能够提升内容质量。

转换:

Rule:

IF

Task = Content Generation


AND

Intent = SEO


THEN

Use Structured Workflow

44.5.3 Rule Evolution核心职责

包括:


(1)Knowledge Rule转换

将知识:

转换:

条件-行为结构。


(2)Rule Evaluation

判断:

规则有效性。


(3)Rule Optimization

提高:

规则准确率。


(4)Rule Version管理

支持:

历史版本。


(5)Rule Conflict解决

规则冲突。


44.5.4 Rule对象模型

WSaiOS定义:

Rule


{


id,


name,


conditions,


actions,


priority,


confidence,


version,


status,


source_knowledge


}

字段:

字段 说明
id 规则ID
name 规则名称
conditions 条件
actions 动作
priority 优先级
confidence 可信度
version 版本
status 状态
source_knowledge 来源知识

44.5.5 Rule模型源码

文件:

models/rule.py

代码:

from dataclasses import dataclass,field

import time



@dataclass
class Rule:


    id:str


    name:str


    conditions:list


    actions:list


    priority:int=0


    confidence:float=0.0


    version:str="1.0"


    status:str="active"


    source_knowledge:str=""


    created_time:float=field(

        default_factory=time.time

    )



    def to_dict(self):


        return {


        "id":

        self.id,


        "name":

        self.name,


        "conditions":

        self.conditions,


        "actions":

        self.actions,


        "priority":

        self.priority,


        "confidence":

        self.confidence,


        "version":

        self.version,


        "status":

        self.status

        }

44.5.6 Knowledge → Rule转换器

新增:

rule_builder.py

作用:

将Knowledge转换为Rule。


代码:

import uuid


from models.rule import Rule



class RuleBuilder:



    def build(
            self,
            knowledge
    ):


        return Rule(


            id=str(uuid.uuid4()),


            name=

            knowledge.entity,


            conditions=[

            {

            "type":

            knowledge.knowledge_type

            }

            ],


            actions=[

            {

            "operation":

            "apply_pattern"

            }

            ],


            priority=1,


            confidence=

            knowledge.confidence,


            source_knowledge=

            knowledge.id

        )

44.5.7 Rule Evaluation规则评价

规则不是生成后永久有效。

需要评价:

Rule


↓

Execute


↓

Observe Result


↓

Update Confidence

评价指标:

Rule Score


=

Success Rate

×

Usage Count

×

Stability

源码:

class RuleEvaluator:



    def evaluate(
            self,
            rule,
            results
    ):


        total=len(results)


        success=0


        for item in results:


            if item["success"]:


                success+=1



        return success / total

44.5.8 Rule Engine规则执行

Rule需要被Decision Engine调用。

文件:

rule_engine.py

代码:

class RuleEngine:



    def __init__(self):


        self.rules=[]



    def register(
            self,
            rule
    ):


        self.rules.append(rule)



    def match(
            self,
            context
    ):


        matched=[]


        for rule in self.rules:


            if self.check(

                rule.conditions,

                context

            ):


                matched.append(rule)



        return matched



    def check(
            self,
            conditions,
            context
    ):


        for condition in conditions:


            if condition["type"] \

            not in context.values():


                return False


        return True

44.5.9 Rule Mutation规则变异

WSaiOS支持:

Rule Evolution。

不是固定规则。

例如:

旧规则:

IF

Keyword Exists


THEN

Generate Content

运行反馈:

发现:

效果一般。

进化:

IF

Keyword

+

Intent

+

Entity


THEN

Generate Structured Content

流程:

Old Rule


     │


     ▼


Feedback


     │


     ▼


Rule Mutation


     │


     ▼


New Rule

44.5.10 Rule Version管理

数据库:

CREATE TABLE rules
(

id TEXT PRIMARY KEY,


name TEXT,


conditions TEXT,


actions TEXT,


confidence REAL,


version TEXT,


status TEXT

);

版本:

Rule v1.0


↓

Rule v1.1


↓

Rule v2.0

44.5.11 Rule Conflict Resolution

多个规则:

可能冲突。

例如:

Rule A:

Priority 1

Use Workflow A

Rule B:

Priority 3

Use Workflow B

解决:

优先级:

Higher Confidence

↓

Higher Priority

↓

Newer Version

源码:

class RuleResolver:



    def resolve(
            self,
            rules
    ):


        return sorted(

            rules,

            key=lambda x:

            (

            x.confidence,

            x.priority

            ),

            reverse=True

        )[0]

44.5.12 Rule Evolution Engine

文件:

rule_learning_engine.py

代码:

class RuleEvolutionEngine:



    def __init__(self):


        self.builder=RuleBuilder()


        self.evaluator=RuleEvaluator()


        self.repository=[]



    def evolve(
            self,
            knowledge
    ):


        rule=(

            self.builder.build(

                knowledge

            )

        )


        self.repository.append(

            rule

        )


        return rule

44.5.13 与Knowledge Learning连接

流程:

Knowledge


     │


     ▼


Rule Builder


     │


     ▼


Rule Repository


     │


     ▼


Decision Engine

调用:

rule = rule_engine.evolve(

knowledge

)

44.5.14 Rule Evolution工程特点

1. 可解释

每条规则:

来源:

Rule

↓

Knowledge

↓

Pattern

↓

Experience

2. 可进化

规则不是静态。


3. 可审计

所有变化保存。


4. 不依赖大模型

核心:

  • 条件;
  • 关系;
  • 逻辑;
  • 评价。
