The new polymer bank note, shown in an image provided by the Bank of England, was unveiled to the public nearly two years after officials first announced it would honor Turing. The Bank of England has unveiled the new £50 note featuring mathematician and computer science pioneer Alan Turing, who helped the Allies win World War II with his code-breaking prowess but died an outcast after facing government persecution over his homosexuality. The bank revealed the note's design and features -- which include a number of clever visual references to Turing's work -- on Thursday, nearly two years after first announcing that it would honor Turing. The banknote will officially enter circulation on June 23, Turing's birthday.

The UK has finally unveiled its Alan Turing bank note, and it's a fitting tribute to the pioneering computer scientist in both what it represents and the technology behind it. To start, the durable polymer £50 bill completes the Bank of England's "most secure" set of notes to date with anti-counterfeiting features appropriate for the legendary WWII codebreaker, including a metallic hologram as well as windows themed around Bletchley Park and a microchip. The imagery is a nod to Turing's many achievements, including some deep cuts that you might not immediately recognize. The mathematical formula you see comes from Turing's influential 1936 paper "On Computable Numbers," a foundational work for computer science. You'll also see pictures of the Automatic Computing Engine Pilot Machine (the trial model for a very early computer) and schematics for the British Bombe codebreaking machine Turing specified.

A very popular algorithm, in Machine Learning, is the Decision Tree Classifier. In this article, the Banknote dataset will be used to illustrate the capabilities of this model. A decision tree is a basic machine learning algorithm that can be used for classification problems. From a high level, a decision tree starts with a basic statement at the top of the tree, and then based on if that statement is True or False, it will then move down a different path to the next condition. This will then continue throughout the duration of the model.

MANCHESTER, ENGLAND - Mathematician Alan Turing, whose cracking of a Nazi code helped the Allies to win World War II but who committed suicide after being convicted for homosexuality, will appear on the Bank of England's new £50 banknote, the central bank said Monday. "As the father of computer science and artificial intelligence, as well as war hero, Alan Turing's contributions were far-ranging and path-breaking," BoE Gov. Mark Carney, who took the final decision on the character selection, said. "Turing is a giant on whose shoulders so many now stand." Turing's electro-mechanical machine, a forerunner of modern computers, unraveled the Enigma code used by Nazi Germany and helped give the Allies an advantage in the naval struggle for control of the Atlantic. His work at Bletchley Park, Britain's wartime code-breaking center, was credited with shortening the war and saving many thousands of lives.
