2.核心概念与联系
在深入探讨人工智能与营销之间的关系之前,我们首先需要了解一下这两个领域的核心概念。
2.1人工智能(AI)
人工智能是一种通过计算机程序模拟人类智能的技术。人工智能的主要目标是让计算机能够像人类一样理解自然语言、学习、推理、认知、感知、理解情感等。人工智能可以分为以下几个子领域:
- 机器学习(ML):机器学习是人工智能的一个子领域,它旨在让计算机能够从数据中自主地学习出规律,从而进行预测和决策。
- 深度学习(DL):深度学习是机器学习的一个子集,它主要通过神经网络来模拟人类大脑的工作方式,以解决复杂的问题。
- 自然语言处理(NLP):自然语言处理是人工智能的一个子领域,它旨在让计算机能够理解、生成和处理自然语言。
2.2营销
营销是一种为了实现组织目标而采取的活动,旨在通过与客户建立长期关系来满足客户需求,从而实现组织收益的管理学领域的一部分。营销活动包括产品策略、价格策略、渠道策略和促销策略等。
