第一部分：AI编程与AgenticAI入门

1.1 什么是AgenticAI？

AgenticAI是指具有自主性和代理能力的人工智能系统，能够理解复杂目标、制定计划并执行任务。与传统的被动响应式AI不同，AgenticAI能够主动思考、决策并采取行动，更像一个真正的"智能代理"。

python

# 简单的AI代理示例
class SimpleAIAgent:def __init__(self, name, expertise):self.name = nameself.expertise = expertiseself.memory = []self.skills = []def learn(self, new_knowledge):self.memory.append(new_knowledge)print(f"{self.name} 学习了: {new_knowledge}")def analyze(self, problem):analysis = f"分析问题: {problem}. 基于我的专业知识: {self.expertise}"return analysisdef solve(self, problem):analysis = self.analyze(problem)solution = f"解决方案建议: 尝试应用{self.expertise}相关方法"self.memory.append(f"解决的问题: {problem}")return f"{analysis}\n{solution}"# 使用示例
coding_agent = SimpleAIAgent("CodeMaster", "Python编程")
coding_agent.learn("Python装饰器的使用方法")
result = coding_agent.solve("如何优化Python代码性能")
print(result)

1.2 AI编程基础

AI编程不仅仅是使用AI工具，更是理解AI的工作原理并能够创建AI应用。以下是AI编程的核心概念：

python

import numpy as np
import matplotlib.pyplot as plt# 简单的神经网络示例
class SimpleNeuralNetwork:def __init__(self, input_size, hidden_size, output_size):self.W1 = np.random.randn(input_size, hidden_size) * 0.01self.b1 = np.zeros((1, hidden_size))self.W2 = np.random.randn(hidden_size, output_size) * 0.01self.b2 = np.zeros((1, output_size))def sigmoid(self, x):return 1 / (1 + np.exp(-x))def forward(self, X):self.z1 = np.dot(X, self.W1) + self.b1self.a1 = self.sigmoid(self.z1)self.z2 = np.dot(self.a1, self.W2) + self.b2self.a2 = self.sigmoid(self.z2)return self.a2def train(self, X, y, learning_rate=0.1, epochs=1000):for i in range(epochs):# 前向传播output = self.forward(X)# 反向传播error = output - ydW2 = np.dot(self.a1.T, error * output * (1 - output))db2 = np.sum(error * output * (1 - output), axis=0, keepdims=True)error_hidden = np.dot(error * output * (1 - output), self.W2.T)dW1 = np.dot(X.T, error_hidden * self.a1 * (1 - self.a1))db1 = np.sum(error_hidden * self.a1 * (1 - self.a1), axis=0)# 更新权重self.W2 -= learning_rate * dW2self.b2 -= learning_rate * db2self.W1 -= learning_rate * dW1self.b1 -= learning_rate * db1if i % 100 == 0:loss = np.mean(np.square(output - y))print(f"Epoch {i}, Loss: {loss:.4f}")# 使用示例
X = np.array([[0, 0], [0, 1], [1, 0], [1, 1]])
y = np.array([[0], [1], [1], [0]])  # XOR问题nn = SimpleNeuralNetwork(2, 4, 1)
nn.train(X, y, epochs=1000)# 测试
test_input = np.array([[0, 0], [0, 1], [1, 0], [1, 1]])
predictions = nn.forward(test_input)
print("预测结果:")
for i, pred in enumerate(predictions):print(f"输入: {test_input[i]} -> 预测: {pred[0]:.4f}")

第二部分：构建个性化学习AI伴侣

2.1 学习进度跟踪与管理

一个有效的学习AI伴侣需要能够跟踪用户的学习进度，并提供个性化的学习建议。

python

2.2 知识图谱构建与应用

知识图谱可以帮助AI理解概念之间的关系，提供更智能的学习路径推荐。

python

class KnowledgeGraph:def __init__(self):self.concepts = {}self.relationships = []def add_concept(self, concept, category, difficulty=1):"""添加概念节点"""self.concepts[concept] = {'category': category,'difficulty': difficulty,'prerequisites': [],'dependencies': []}def add_relationship(self, source, target, relationship_type):"""添加概念间关系"""if source in self.concepts and target in self.concepts:self.relationships.append({'source': source,'target': target,'type': relationship_type})# 更新前置依赖关系if relationship_type == 'prerequisite':self.concepts[target]['prerequisites'].append(source)self.concepts[source]['dependencies'].append(target)def find_learning_path(self, target_concept, current_knowledge=None):"""寻找学习路径"""if current_knowledge is None:current_knowledge = []if target_concept not in self.concepts:return f"未找到概念: {target_concept}"# 使用BFS寻找最短学习路径visited = set(current_knowledge)queue = [(target_concept, [target_concept])]learning_path = []while queue:current, path = queue.pop(0)# 检查是否已掌握所有前置知识prerequisites = self.concepts[current]['prerequisites']missing_prereqs = [p for p in prerequisites if p not in visited]if not missing_prereqs:# 所有前置知识都已掌握，可以学习当前概念if current not in visited:learning_path.append(current)visited.add(current)# 添加依赖项到队列for dep in self.concepts[current]['dependencies']:if dep not in visited:queue.append((dep, path + [dep]))else:# 还有未掌握的前置知识，先学习前置知识for prereq in missing_prereqs:if prereq not in visited:queue.append((prereq, path + [prereq]))return learning_path if learning_path else [target_concept]def visualize_knowledge_graph(self):"""可视化知识图谱（简化版）"""print("知识图谱:")print("-" * 30)for concept, info in self.concepts.items():print(f"概念: {concept}")print(f"  类别: {info['category']}")print(f"  难度: {info['difficulty']}")print(f"  前置知识: {', '.join(info['prerequisites'])}")print(f"  后续概念: {', '.join(info['dependencies'])}")print()# 使用示例
