Summary

In the last chapter, we saw techniques that apply at a finer granular level of data, working with individual data values. In this chapter, we consider data in bulk, at a much more macrolevel, to extract features, patterns, and their relative weights. Interestingly Machine Learning is a double-edged sword. It can be used to create fake content and also to detect fake content. A good example is Google’s “ ...
