I want to be able to input a block of text and then have it guess a string within a predefined range (i.e. a string that starts with three letters and ends with five numbers like "XXX12345", etc). Ideally, the string it will be guessing will be somewhere in the block of text, but sometimes it won't be.
I have been struggling where to begin on this or if I am even going in the right direction for considering Machine/Deep learning to try to do this.
Help!
