Fun Machine Learning Facts

Machine learning reduced Google Translate’s error rate by 60%.

Google Translate was initially released in 2006 with a phrase-based machine translation algorithm, and it wasn’t until ten years later, in 2016, that it started to translate with decent quality. This improvement was achieved by introducing Google’s neural machine translation system into it -- a system that uses an artificial neural network to translate whole sentences instead of translating word by word.

Machine Learning FAQs

How does machine learning work?

Machine learning is a form of artificial intelligence that aims to enable machines to think in a similar way as humans would. It relies on using past experiences to improve and learn. This is done by feeding the machine an enormous amount of data it can use to find patterns and use them in future cases.

(Data Robot)

What is the difference between machine learning and deep learning?

While both machine learning and deep learning fall under the broad umbrella of artificial intelligence, deep learning requires little to no human intervention. This is because deep learning uses an artificial neural network to learn and make intelligent decisions independently, unlike machine learning which only makes decisions based on previous experiences.

What is machine learning used for?

According to machine learning facts, the are many use cases for machine learning already, and businesses are always finding new ways to use it. Some of the most popular examples of companies using ML are search engines, spam filters, recommendations and fraud detection systems, voice recognition technology, etc.

(Royal Society)

When was machine learning invented?

A lesser known machine learning statistic is that the term “machine learning” was originally coined by Arthur Samuel, a computer scientist working in IBM, in 1952. He created the world’s first AI in the form of a computer program capable of playing checkers against a human opponent and improving after each game played. He called this ability machine learning.
