AI学习和实战

一、人工智能分类

判别式人工智能：通过分析输入数据和对应的输出标签之间的关系来进行决策和分类。

生成式人工智能：AIGC（Artificial Intelligence Generated Content）是人工智能1.0时代进入2.0时代的重要标志。

二、人工智能发展史

1、2016年3月15日，google旗下机器学习(AlphaGo)首次战胜人类职业围棋冠军。

2、人工智能技术在各个领域的应用不断拓展。自动驾驶、智能家居、智能医疗。

3、2018年，OpenAI公司开发了GPT-2模型，大规模预训练语言模型（LLM）。

4、2022年，人工智能在多模态、跨领域、泛知识等方面取得了重大突破。微软发布了MUM，一种能够理解多种语言和多种媒体的多模态通用模型；阿里巴巴发布了ET城市大脑4.0，利用人工智能优化城市治理和服务。

5、2023年，人工智能大爆发，OpenAI发布了GPT-4,微软推出new Bing,百度推出文心一言，DeepMind发布了AlphaGo Zero 2.0，一种完全自主学习的围棋程序，能够超越任何人类或计算机对手；IBM发布了Neuro-Symbolic Concept Learner，一种能够从图像中学习概念并用自然语言表达的神经符号模型。

6、2024年2月15日，OpenAI发布的人工智能文生视频大模型sora。

三、国内人工智能平台

1、阿里云：阿里灵杰

提供ai代码生成器：通义灵码。

2、百度AI开放平台：百度AI开放平台-全球领先的人工智能服务平台
