As members of the Machine Learning community, it would be a good idea for us all to have an idea of the history of the sector we work in. Although we are currently living through an authentic boom in Machine Learning, this field has not always been so prolific, going through periods of high expectations and advances as well as “winters” of severe stagnation.

Birth [1952 – 1956]

1950 — Alan Turing creates the “Turing Test” to determine whether or not a machine is truly intelligent. In order to pass the test, the machine must be capable of making a human believe that it is another human instead of a computer.

1952 — Arthur Samuel writes the first computer program capable of learning. The software was a program that could play checkers and improved with each game it played.

1956 — Martin Minsky and John McCarthy, with the help of Claude Shannon and Nathan Rochester, held a conference at Dartmouth in 1956, which is considered to be where the field of Artificial Intelligence was born. Minsky convinced the attendees to adopt the term “Artificial Intelligence” as the name for the new field.

1958 — Frank Rosenblatt designs the Perceptron, the first artificial neural network.

First Winter of AI [1974 – 1980]

In the second half of the 1970s, the field suffered its first “winter.” Various agencies that had been financing AI research cut funds after years of high expectations and few actual advances.

1979 — Students at Stanford University invent the “Stanford Cart,” a mobile robot capable of moving autonomously around a room while avoiding obstacles.

1967 — The algorithm “Nearest Neighbor” is written. This milestone is considered the birth of the field of pattern recognition in computers.

The Explosion of the 1980s [1980 – 1987]

The 80s are known as the birth of expert systems, based on rules. These were rapidly adopted by the corporate sector, generating new interest in Machine Learning.

1981 — Gerald Dejong introduces the concept of “Explanation Based Learning” (EBL), in which a computer analyzes the training data and creates general rules allowing the less important data to be discarded.

1985 — Terry Sejnowski invents NetTalk, which learns to pronounce words in the same way a child would learn to do.

Second AI Winter [1987 – 1993]

At the end of the 1980s and the beginning of the 90s, AI experienced a second “winter.” This time, its effects lasted for several years and the reputation of the field did not fully recover until the early 2000s.

1990s — Work in Machine Learning moves from a knowledge-driven focus to a data-driven one. Scientists begin to create programs that analyze large quantities of data and extract conclusions from the results.

1997 — The computer Deep Blue, by IBM, beats world chess champion Gary Kaspárov.

Explosion and Commercial Adoption [2006 – Present Day]

The growth in the potential for calculation together with the great abundance of available data have relaunched the field of Machine Learning. Many businesses are moving their companies towards data and incorporating Machine Learning into its processes, products and services in order to gain an edge over their competition.

2006 — Geoffrey Hinton coined the phrase “Deep Learning” to explain the new architectures of profound neural networks capable of learning much better models.

2011 — The Watson computer by IBM beats it human competitors at Jeopardy, a game show that consists of answering questions in natural language.

2012 — Jeff Dean, at Google, with the assistance of Andrew Ng (Stanford University), leads the project GoogleBrain, which developed a deep neural network using all of the capacity of the Google infrastructure to detect patterns in videos and images.

2012 — Geoffrey Hinton leads the winning team in the Computer Vision contest at Imagenet using a deep neural network (DNN). The team won by a large margin, giving rise to the current explosion of Machine Learning based on DNNs.

2012 — The research laboratory Google X uses GoogleBrain to autonomously analyze Youtube videos and detect those containing cats.

2014 — Facebook develops DeepFace, an algorithm based on DNNs capable of recognizing people with the same precision as a human being.

2014 — Google buys DeepMind, a British deep learning startup that had recently demonstrated DNN capabilities with an algorithm capable of playing Atari games by simply viewing the pixels on the screen, the same way a person would. The algorithm, after hours of training, was capable of beating human experts in the games.

2015 — Amazon launches its own Machine Learning platform.

2015 — Microsoft creates the “Distributed Machine Learning Toolkit”, which allows for the efficient distribution of machine learning problems to multiple computers.

2015 — Elon Musk and Sam Altman, among others, found the non-profit organization OoenAI, providing it with one billion dollars with the objective of ensuring that artificial intelligence has a positive impact on humanity.

2016 – Google DeepMind beats professional Go player Lee Sedol five games to one at what is considered to be one of the most complex board games.  Expert Go players confirmed that the algorithm was capable of making “creative” moves that they had never seen before.

Today, we are experiencing a third explosion in artificial intelligence. Although there are skeptics who say we cannot discard the possibility of a third winter, this time the advances in the sector are being applied to business to the point of creating whole new markets and producing significant changes in the strategies of both big and small businesses.

The wide availability of data seems to be the fuel behind these algorithm motors which, in turn, are surpassing the limitations of calculation that existed prior to distributed computing. All of this seems to indicate that we should continue to have access to more and more data that will feed our algorithms will the scientific community does not seem to be running out of ideas to continue advancing the field. 2017 and the following years promise to be truly frenetic.
