Making Use of Big Data

Although today’s most exciting machine learning research is found in the realm of big data—computer vision, natural language processing, autonomous vehicles, and so on—most business applications are much smaller scale, using what might be termed, at best, “medium” data. As noted in Chapter 12, Advanced Data Preparation, true big data work requires access to datasets and computing facilities generally found only at very large tech companies or research universities. Even then, the actual job of using these resources is often primarily a feat of data engineering, which simplifies the data greatly before its use in conventional business applications.

The good news is that the headline-making research conducted at big data ...
