I can guarantee that anybody reading this blog uses machine learning dozens of times each day without even realizing it. When you perform a web, search using Google or Bing, for instance, the search engine works so well because their software has figured out how to predict searches and rank pages for you.
I chose the title for this blog a bit tongue in cheek. You see, there are numerous blog posts about how to “properly” redact PDF files. While all of those other blog posts correctly explain the challenges that makes redacting PDF files difficult and outline all of the steps that one must take to ensure private information is completely and irreversibly redacted, all of those blog posts fail to mention one critical idea that anyone tasked with the important job of redacting electronic documents should be aware of -- automation.
