本书通过讲解监督学习的两大支柱回归和分类将机器学习纳入统一视角展开讨论。书中首先讨论基础知识，包括均方、*小二乘和最大似然方法、岭回归、贝叶斯决策理论分类、逻辑回归和决策树。然后介绍新近的技术，包括稀疏建模方法，再生核希尔伯特空间中的学习、支持向量机中的学习、关注EM算法的贝叶斯推理及其近似推理变分版本、蒙特卡罗方法、聚焦于贝叶斯网络的概率图模型、隐马尔科夫模型和粒子滤波。此外，本书还深入讨论了降维和隐藏变量建模。全书以关于神经网络和深度学习架构的扩展章节结束。此外，书中还讨论了统计参数估计、维纳和卡尔曼滤波、凸性和凸优化的基础知识，其中，用一章介绍了随机逼近和梯度下降族的算法，并提出了分布式优化的相关概念、算法和在线学习技术。
