Making informative visualizations (sometimes calledplots) is one of the most important tasks in data analysis. It may be a part of the exploratory process—for example, to help identify outliers or needed data transformations, or as a way of generating ideas for models. For others, building an...

You will learn about training data, and how to use a set of data to discover potentially predictive relationships. As you build the movie recommendation system, you will learn how to train algorithms using training data so you can pr...
在所有先前的章节中,我们一直认为我们的数据集是从隐式数据生成过程p_data以及所有算法假设x[i] ∈ X为独立同分布的(IID)并进行均匀采样。 我们假设X足够准确地表示p_data,以便算法可以学习使用有限的初始知识进行概括。 相反,在本章中,我们感兴趣的是直接建模p_data,而没有任何具体限制(例如,高斯混合模型通过对...
