What we learned
Machine learning is a very broad spectrum. To put it simply, it is computers doing stuff without being programmed to do so. One way they do this is using past data to build up confidence in analysing things where there is similarities. An easy thing to do is analyse text to see where similar words might go together, for example if I typed gang after blahaj every time then the computer could suggest I type gang, without ever being programmed explicitly with blahaj or gang.
