人工智能概述

人工智能（AI）是通过计算机系统模拟人类智能的技术，涵盖机器学习、自然语言处理、计算机视觉等领域。其核心目标是使机器具备学习、推理、规划和解决问题的能力。

核心技术

机器学习：通过数据训练模型，实现预测或决策。包括监督学习（如分类、回归）、无监督学习（如聚类）和强化学习（如AlphaGo）。

深度学习：基于神经网络的机器学习分支，适用于图像识别、语音处理等复杂任务。典型模型包括卷积神经网络（CNN）和循环神经网络（RNN）。

自然语言处理（NLP）：使机器理解、生成人类语言，应用于聊天机器人（如ChatGPT）、机器翻译等。

应用场景

医疗：AI辅助诊断（如肺癌筛查）、药物研发加速。
金融：欺诈检测、量化交易、风险评估。
自动驾驶：结合传感器和深度学习实现车辆环境感知与决策。
制造业：预测性维护、智能质检。

挑战与伦理

数据隐私：训练需大量数据，可能涉及用户隐私泄露风险。
算法偏见：训练数据偏差导致歧视性结果（如招聘算法中的性别偏见）。
就业影响：自动化可能取代部分重复性工作，需重新规划劳动力结构。

发展趋势

通用人工智能（AGI）：当前AI多为专用型，未来或向人类水平的通用智能迈进。
边缘AI：将AI部署到终端设备（如手机、IoT设备），减少云端依赖。
可解释性：提升模型透明度，便于人类理解其决策逻辑。

代码示例（Python深度学习框架Keras）：

from keras.models import Sequential
from keras.layers import Dense

model = Sequential()
model.add(Dense(units=64, activation='relu', input_dim=100))
model.add(Dense(units=10, activation='softmax'))
model.compile(loss='categorical_crossentropy', optimizer='sgd', metrics=['accuracy'])

数学公式（损失函数交叉熵）：
[ L(y, \hat{y}) = -\sum_{i} y_i \log(\hat{y}_i) ]

人工智能持续推动技术革新，需平衡发展速度与社会责任，确保技术造福人类。
