R AI Machine Learning Explained Rodney BrooksAn essay in my series on the Future of Robotics and Artificial Intelligence. Much of the recent enthusiasm about Artificial Intelligence is based on the spectacular recent successes of machine learning, itself often capitalized as Machine Learning, and often referred to as ML. It has become common in the technology world that the presence of ML in a company, in a development process, or in a product is viewed as a certification of technical superiority, something that will outstrip all competition. Machine Learning is what has enabled the new assistants in our houses such as the Amazon Echo Alexa and Google Home by allowing them to reliably understand as we speak to them. Machine Learning is how Google chooses what advertisements to place, how it saves enormous amounts of electricity at its data centers, and how it labels images so that we can search for them with key words. Machine learning is how Deep. Mind a Google company was able to build a program called Alpha Go which beat the world Go champion. Machine Learning is how Amazon knows what recommendations to make to you whenever you are at its web site. Machine Learning is how Pay. Pal detects fraudulent transactions. Machine Learning is how Facebook is able to translate between languages. And the list goes on While ML has started to have an impact on many aspects of our life, and will more and more so over the coming decades, some sobriety is not out of place. Machine Learning1 is not magic. Neither AI programs, nor robots, wander around in the world ready to learn about whatever there is around them. Every successful application of ML is hard won by researchers or engineers carefully analyzing the problem that is at hand. They select one or many different ML algorithms, and custom design how to connect them together and to the data. In some cases there is an extensive period of training on very large sets of data before the algorithm can be run on the problem that is being solved. In that case there may be months of work to do in collecting the right sort of data from which ML will actually learn. In other cases the learning algorithm will be integrated in to the application and will learn while doing the task that is desiredit might require some training wheels in the early stages, and they too must be designed. In any case there is always a big design project about how, when the ultimate system is operational, the data that comes in will be organized, processed and mapped before it reaches the ML component of the system. When we are tending plants we pour water on them and perhaps give them some fertilizer and they grow. I think many people in the press, in management, and in the non technical world have been dazzled by the success of Machine Learning, and have come to think of it a little like water or fertilizer for hard problems. They often mistakenly believe that a generic version will work on any and all problems. But while ML can sometimes have miraculous results it needs to be carefully customized after the DNA of the problem has beed analyzed. And even then it might not be what is neededto extend the metaphor, perhaps it is the climate that needs to be adjusted and no amount of fertilizer or ML will do the job. How does Machine Learning work, and is it the same as when a child or adult learns something new The examples above certainly seem to cover some of the same sort of territory, learning how to understand a human speaking, learning how to play a game, learning to name objects based on their appearance. Machine Learning started with games. In the early 1. 94. They had been built, using the technology of vacuum tubes, to calculate gunnery tables and to decrypt coded military communications of the enemy. Even then, however, people were starting to think about how these computers might be used to carry out intelligent activities, fifteen years before the term Artificial Intelligence was first floated by John Mc. Carthy. Alan Turing, who in 1. Donald Michie, a classics student from Oxford later he would earn a doctorate in genetics, worked together at Bletchley Park, the famous UK code breaking establishment that Churchill credited with subtracting years from the war. Turing contributed to the design of the Colossus computer there, and through a key programming breakthrough that Michie made the design of the second version of the Colossus was changed to accommodate his ideas ever better. Meanwhile at the local pub the pair had a weekly chess game together and discussed how to program a computer to play chess, but they were only able to get as far as simulations with pen and paper. In the United States right after the war, Arthur Samuel. ILLIAC computer at the University of Illinois at Urbana Champaign. While the computer was still being built he planned out how to program it to play checkers or draughts in British English, but left in 1. IBM before the University computer was completed. At IBM he worked on both vacuum tubes and transistors to bring IBMs first commercial general purpose digital computers to market. On the side he was able to implement a program that by 1. This was one of the first non arithmetical programs to run on general purpose digital computers, and has been called the first AI program to run in the United States. Samuel continued to improve the program over time and in 1. Download Google Chrome Offline Installer Windows Xp. But Samuel wondered whether the improvements he was making to the program by hand could be made by the machine itself. In 1. 95. 9 he published a paper titled Some Studies in Machine Learning Using the Game of Checkers2, the first time the phrase Machine Learning was usedearlier there had been models of learning machines, but this was a more general concept. The first sentence in his paper was The studies reported here have been concerned with programming of a digital computer to behave in a way which, if done by human beings or animals, would be described as involving the process of learning. Right there is his justification for using the term learning, and while I would not quibble with it, I think that it may have had some unintended consequences which we will explore towards the end of this post. What Samuel had realized, demonstrated, and exploited, was that digital computers were by 1. Machine Learning on appropriate parts of the problem. This is exactly what has lead, almost 6. ML is now having on the world. Age Of Empires 2 Mods Game Of Thrones'>Age Of Empires 2 Mods Game Of Thrones. One of the two learning techniques Samuel described was something he called rote learning, and today would be labelled as a well known programming technique called memoization. The other learning technique that he investigated involved adjusting numerical weights on how much the program should believe each of over thirty measures of how good or bad a particular board position was for the program or its human opponent. This is closer in spirit to techniques in modern ML. By improving this measure the program could get better and better at playing. By 1. 96. 1 his program had beat the Connecticut state checker champion. Another first for AI, and enabled by the first ML program. Arthur Samuel built his AI and ML systems not as an academic researcher but as a scholar working on his own time apart from his day job. However he had an incredible advantage over all the AI academic researchers. Algorithm Wikipedia. Flow chart of an algorithm Euclids algorithm for calculating the greatest common divisor g. A and B. The algorithm proceeds by successive subtractions in two loops IF the test B A yields yes or true more accurately the numberb in location B is greater than or equal to the numbera in location A THEN, the algorithm specifies B B A meaning the number b a replaces the old b. Similarly, IF A B, THEN A A B. The process terminates when the contents of B is 0, yielding the g. A. Algorithm derived from Scott 2. Tausworthe 1. 97. In mathematics and computer science, an algorithm   listenAL g ridh m is an unambiguous specification of how to solve a class of problems. Algorithms can perform calculation, data processing and automated reasoning tasks. An algorithm is an effective method that can be expressed within a finite amount of space and time1 and in a well defined formal language2 for calculating a function. Starting from an initial state and initial input perhaps empty,4 the instructions describe a computation that, when executed, proceeds through a finite5 number of well defined successive states, eventually producing output6 and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic some algorithms, known as randomized algorithms, incorporate random input. The concept of algorithm has existed for centuries however, a partial formalization of what would become the modern algorithm began with attempts to solve the Entscheidungsproblem the decision problem posed by David Hilbert in 1. Subsequent formalizations were framed as attempts to define effective calculability8 or effective method 9 those formalizations included the GdelHerbrandKleenerecursive functions of 1. Alonzo Churchs lambda calculus of 1. Emil Posts Formulation 1 of 1. Alan Turings Turing machines of 1. Giving a formal definition of algorithms, corresponding to the intuitive notion, remains a challenging problem. Etymology. The word algorithm is a combination of the Latin word algorismus, named after Al Khwarizmi1. Greek word arithmos, i. Al Khwrizm Persian, c. Persian mathematician, astronomer, geographer, and scholar in the House of Wisdom in Baghdad, whose name means the native of Khwarezm, a region that was part of Greater Iran and is now in Uzbekistan. About 8. 25, he wrote a treatise in the Arabic language, which was translated into Latin in the 1. Algoritmi de numero Indorum. This title means Algoritmi on the numbers of the Indians, where Algoritmi was the translators Latinization of Al Khwarizmis name. Al Khwarizmi was the most widely read mathematician in Europe in the late Middle Ages, primarily through his other book, the Algebra. In late medieval Latin, algorismus, English algorism, the corruption of his name, simply meant the decimal number system. In the 1. 5th century, under the influence of the Greek word number cf. Latin word was altered to algorithmus, and the corresponding English term algorithm is first attested in the 1. In English, it was first used in about 1. Chaucer in 1. 39. English adopted the French term, but it wasnt until the late 1. English. Another early use of the word is from 1. Carmen de Algorismo composed by Alexandre de Villedieu. It begins thus Haec algorismus ars praesens dicitur, in qua Talibus Indorum fruimur bis quinque figuris. Algorism is the art by which at present we use those Indian figures, which number two times five. Codice Biblia Software Download more. The poem is a few hundred lines long and summarizes the art of calculating with the new style of Indian dice, or Talibus Indorum, or Hindu numerals. Informal definition. An informal definition could be a set of rules that precisely defines a sequence of operations. Generally, a program is only an algorithm if it stops eventually. A prototypical example of an algorithm is the Euclidean algorithm to determine the maximum common divisor of two integers an example there are others is described by the flow chart above and as an example in a later section. Boolos, Jeffrey 1. No human being can write fast enough, or long enough, or small enough smaller and smaller without limit. But humans can do something equally useful, in the case of certain enumerably infinite sets They can give explicit instructions for determining the nth member of the set, for arbitrary finite n. Such instructions are to be given quite explicitly, in a form in which they could be followed by a computing machine, or by a human who is capable of carrying out only very elementary operations on symbols. An enumerably infinite set is one whose elements can be put into one to one correspondence with the integers. Thus, Boolos and Jeffrey are saying that an algorithm implies instructions for a process that creates output integers from an arbitrary input integer or integers that, in theory, can be arbitrarily large. Thus an algorithm can be an algebraic equation such as y m n two arbitrary input variables m and n that produce an output y. But various authors attempts to define the notion indicate that the word implies much more than this, something on the order of for the addition example Precise instructions in language understood by the computer2. The concept of algorithm is also used to define the notion of decidability. That notion is central for explaining how formal systems come into being starting from a small set of axioms and rules. In logic, the time that an algorithm requires to complete cannot be measured, as it is not apparently related with our customary physical dimension. From such uncertainties, that characterize ongoing work, stems the unavailability of a definition of algorithm that suits both concrete in some sense and abstract usage of the term. Formalization. Algorithms are essential to the way computers process data. Many computer programs contain algorithms that detail the specific instructions a computer should perform in a specific order to carry out a specified task, such as calculating employees paychecks or printing students report cards. Thus, an algorithm can be considered to be any sequence of operations that can be simulated by a Turing complete system. Authors who assert this thesis include Minsky 1. Savage 1. 98. 7 and Gurevich 2. Minsky But we will also maintain, with Turing. Although this may seem extreme, the arguments. Gurevich. Turings informal argument in favor of his thesis justifies a stronger thesis every algorithm can be simulated by a Turing machine. Savage 1. 98. 7, an algorithm is a computational process defined by a Turing machine. Typically, when an algorithm is associated with processing information, data can be read from an input source, written to an output device and stored for further processing. Stored data are regarded as part of the internal state of the entity performing the algorithm. In practice, the state is stored in one or more data structures. For some such computational process, the algorithm must be rigorously defined specified in the way it applies in all possible circumstances that could arise. That is, any conditional steps must be systematically dealt with, case by case the criteria for each case must be clear and computable. Because an algorithm is a precise list of precise steps, the order of computation is always crucial to the functioning of the algorithm.
