WSaiOS Cognitive Learning Engine学习引擎源码实现
44.3 Pattern Learning模式学习模块源码实现
在44.2节中,我们完成了:
- Experience对象模型;
- Experience Repository;
- Experience Analyzer;
- Experience评分体系;
- Feedback → Experience转换。
此时Learning Engine已经具备:
id="p3j6ds"
Feedback
↓
Experience
↓
Experience Memory
但是,单个经验只能代表一次事件。
真正的学习能力来自:
从大量经验中发现重复规律。
因此WSaiOS设计:
Pattern Learning Module
模式学习模块
44.3.1 Pattern Learning定位
Pattern Learning负责:
将:
id="m8q5we"
大量Experience
↓
共同特征
↓
行为模式
↓
可复用策略
例如:
100次内容生成任务:
经验:
Experience 1:
Keyword Analysis
↓
Semantic Structure
↓
Schema Validation
↓
Success
Experience 2:
Keyword Analysis
↓
Semantic Structure
↓
Schema Validation
↓
Success
Experience 3:
Keyword Analysis
↓
Semantic Structure
↓
Schema Validation
↓
Success
Pattern Learning发现:

High Success Workflow Pattern
Keyword Analysis
↓
Semantic Structure
↓
Schema Validation

44.3.3 Pattern核心对象
WSaiOS定义:
id="q0x1cv"
Pattern
{
id,
name,
type,
conditions,
actions,
frequency,
success_rate,
confidence,
source_experiences
}
字段:
| 字段 | 说明 |
|---|---|
| id | 模式ID |
| name | 模式名称 |
| type | 模式类型 |
| conditions | 触发条件 |
| actions | 执行行为 |
| frequency | 出现次数 |
| success_rate | 成功率 |
| confidence | 可信度 |
| source_experiences | 来源经验 |
44.3.4 Pattern模型源码
文件:
cognitive_learning/models/pattern.py
代码:
from dataclasses import dataclass
@dataclass
class Pattern:
id:str
name:str
pattern_type:str
conditions:list
actions:list
frequency:int=0
success_rate:float=0.0
confidence:float=0.0
def to_dict(self):
return {
"id":
self.id,
"name":
self.name,
"type":
self.pattern_type,
"conditions":
self.conditions,
"actions":
self.actions,
"frequency":
self.frequency,
"success_rate":
self.success_rate,
"confidence":
self.confidence
}
44.3.5 Pattern Learning核心流程
流程:
id="7q9v6x"
Experience

Feature Extraction
│
▼
Similarity Analysis
│
▼
Pattern Discovery
│
▼
Pattern Evaluation
│
▼
Pattern Repository
44.3.6 Feature Extraction特征提取
经验:
{
"task":
"content generation",
"action":
{
"workflow":
[
"analysis",
"generate",
"validate"
]
}
}
提取:
id="9t1a3k"
Feature:
task:
content_generation
workflow:
analysis_generate_validate
源码:
class FeatureExtractor:
def extract(
self,
experience
):
return {
"task":
experience.task,
"actions":
list(
experience.action.keys()
)
}
44.3.7 Pattern Discovery模式发现
Pattern发现算法:
WSaiOS采用:
Symbolic Similarity Matching
不是神经网络。
流程:
Experience A
│
▼
Feature A
Experience B
│
▼
Feature B
│
Similarity Compare
│
▼
Same Pattern
源码:
class PatternDiscovery:
def compare(
self,
feature1,
feature2
):
score=0
for key in feature1:
if key in feature2:
if feature1[key]==feature2[key]:
score+=1
return score
def discover(
self,
experiences
):
patterns=[]
for exp in experiences:
feature=(
FeatureExtractor()
.extract(exp)
)
patterns.append(
feature
)
return patterns
44.3.8 Pattern Analyzer模式分析器
负责:
- 成功率统计;
- 频率统计;
- 价值判断。
文件:
pattern_analyzer.py
代码:
class PatternAnalyzer:
def analyze(
self,
experiences
):
total=len(experiences)
success=0
for exp in experiences:
if (
exp.evaluation
.get("success")
):
success+=1
return {
"frequency":
total,
"success_rate":
success/total
}
44.3.9 Pattern评分机制
WSaiOS定义:
Pattern Confidence:
公式:
Confidence
=
Frequency Weight
×
Success Rate
×
Stability
例如:
一个模式:
出现次数:
100
成功率:
95%
稳定性:
90%
计算:
0.855
44.3.10 Pattern Repository
目录:
repository_pattern.py
负责:
Pattern
保存
查询
更新
删除
数据库:
CREATE TABLE patterns
(
id TEXT PRIMARY KEY,
name TEXT,
type TEXT,
conditions TEXT,
actions TEXT,
frequency INTEGER,
success_rate REAL,
confidence REAL
);
44.3.11 Pattern Evolution模式进化
Pattern不是固定。
随着新经验进入:
旧Pattern:
Generate
↓
Validate
发现:
增加:
Semantic Analysis
更新:
Analyze
↓
Generate
↓
Validate
进化流程:

44.3.12 Pattern Learning Engine源码
文件:
pattern_engine.py
代码:
class PatternLearningEngine:
def __init__(self):
self.extractor=FeatureExtractor()
self.discovery=PatternDiscovery()
self.analyzer=PatternAnalyzer()
def learn(
self,
experiences
):
features=[]
for exp in experiences:
features.append(
self.extractor.extract(exp)
)
analysis=(
self.analyzer.analyze(
experiences
)
)
return {
"features":
features,
"analysis":
analysis
}
44.3.13 与Experience Learning连接

调用:
patterns = pattern_engine.learn(
experience_list
)
44.3.14 Pattern Learning工程特点
1. 符号化学习
基于:
- Entity;
- Attribute;
- Relation;
- Rule。
2. 可解释
每个Pattern:
来源明确:
Pattern
↓
Experiences
3. 可持续进化
新经验:
持续优化。
4. 支持领域扩展
例如:
医疗:
Symptom
↓
Diagnosis
↓
Treatment
商业:
Customer
↓
Behavior
↓
Decision
