This essay is going to define machine learning and describe some of the different areas within machine learning. It will summarise some of the algorithms used to achieve machine learning and describe some of the situations in which they can be applied, then compare these to human learning techniques and comment on there similarities and differences. It will then discuss Raymond Kurzweils singularity theories and its opposing views. Intro Machine learning is having a large impact on the way that computers can be used in many ways. There are many implementations that vary in complexity. Google finishing off sentences when a search term is entered (Economist,2014)and Netflix having the ability to recommend films that you may enjoy to IBM's cognitive computing program 'Watson' that has beaten human opponents on jeopardy. The area is constantly growing, Facebook have recently invested in their own Artificial Intelligence (A.I) team that are working on extracting the emotions and behaviour implied by posts to its site (Simonite,2013) and IBM are investing one billion dollars in a new division to find uses for Watson (Economist,2014). Google have seen the importance of A.I and machine learning which can be seen by the number of artificial intelligence companies that they have purchased. They have just added to there portfolio of recent A.I related purchases with the acquisition of Deep Mind which they purchased for a reported four hundred million pounds. This is impressive to say that Deep Mind had not even released a product at this point. (Bradshaw et al, 2014) There is very little known about what deep minds technology is capable of but it is known to be in the area of general machine learning algorithms. It has been said that De... ... middle of paper ... ... of the brain its self. His reasons for scepticism are that the human consciousness is a result of non linear interactions between the billions of cells that make up the human body. However Nicolellis believes that computing technology will be implanted into our brains to improve brain function before a computing system that can re create human consciousness is possible. (Regelado,2014)Nicollelis's Duke Lab have recently published a study that has demonstrated a way to allow rats to see infra red light. They achieve this by wiring an infra-red sensor to electrodes implanted into a section of the brain called the somatosensory cortex. This is the first experiment that has successfully used a neural implant to give an animal a new sense.(Thomson et al ,2014) This shows that Nicollelis is serious with his claims and that his opposition to kurzweils claims carry weight.

  • The Turing Test

    1428 Words  | 3 Pages

    One of the hottest topics that modern science has been focusing on for a long time is the field of artificial intelligence, the study of intelligence in machines or, according to Minsky, “the science of making machines do things that would require intelligence if done by men”.(qtd in Copeland 1). Artificial Intelligence has a lot of applications and is used in many areas. “We often don’t notice it but AI is all around us. It is present in computer games, in the cruise control in our cars and the servers that route our email.” (BBC 1). Different goals have been set for the science of Artificial Intelligence, but according to Whitby the most mentioned idea about the goal of AI is provided by the Turing Test. This test is also called the imitation game, since it is basically a game in which a computer imitates a conversating human. In an analysis of the Turing Test I will focus on its features, its historical background and the evaluation of its validity and importance.

    To begin, the main issue of development of Artificial Intelligence is the economic factors. Firstly, one of the main negative effects of AI on economy is unemployment. According to the suggesting of Carl Benedikt Frey and Michael A. Osborne of Oxford University during next 20 years 47 per cent of all USA jobs under the threat and will be replaced with intelligence machines (Vincent). If jobs will be automated, people will lose their workplaces and it is becomes one of the harmful problems not only for economy, but also for society. Because, if people will not have a workplace, they will not be able to provide their needs. Furthermore, development of AI can be a reason of increasing inequality of wages. For instance, the salaries of computer workers approximately earn 10 to 15 percent more than others. (Frey and Osborne). It is also one of the economic problems because it can lead to discontent of workers who hav...

    Imagine asking your computer to do something in the same way you would ask a friend to do it. Without having to memorize special commands that only it could understand. For computer scientists this has been an ambitious goal; that can further simplify computers. Artificial Intelligence, a system that can mimic human intelligence by performing task that usually only a human can do, usually has to use a form of natural language processing. Natural language processing, a sub-field of computer science and artificial intelligence, concerns the successfully interaction between a computer and a human. Currently one of the best examples of A.I.(Artificial Intelligence) is IBM 's Watson. A machine that gained popularity after appearing on the show

    The approach to artificial intelligence should be proceeded with caution. Throughout recent years and even decades before, it has been a technological dream to produce artificial intelligence. From movies, pop culture, and recent technological advancements, there is an obsession with robotics and their ability to perform actions that require human intelligence. Artificial intelligence has become a real and approachable realization today, but should be approached with care and diligence. Humans can create advanced artificial intelligence but should not because of the harm they may cause, the monumental advancement needed in the technology, and that its harm outweighs its benefits.

  • Computers Mimic The Human Mind

    1440 Words  | 3 Pages

    Most of the day the human mind is taking in information, analyzing it, storing it accordingly, and recalling past knowledge to solve problems logically. This is similar to the life of any computer. Humans gain information through the senses. Computers gain similar information through a video camera, a microphone, a touch pad or screen, and it is even possible for computers to analyze scent and chemicals. Humans also gain information through books, other people, and even computers, all of which computers can access through software, interfacing, and modems. For the past year speech recognition software products have become mainstream(Lyons,176). All of the ways that humans gain information are mimicked by computers. Humans then proceed to analyze and store the information accordingly. This is a computer's main function in today's society. Humans then take all of this information and solve problems logically. This is where things get complex. There are expert systems that can solve complex problems that humans train their whole lives for. In 1997, IBM's Deep Blue defeated the world champion in a game of chess(Karlgaard, p43). Expert systems design buildings, configure airplanes, and diagnose breathing problems. NASA's Deep Space One probe left with software that lets the probe diagnose problems and fix itself(Lyons).

  • Artificial Intelligence and its Effects on Business

    In order to see how artificial intelligence plays a role on today’s society, I believe it is important to dispel any misconceptions about what artificial intelligence is. Artificial intelligence has been defined many different ways, but the commonality between all of them is that artificial intelligence theory and development of computer systems that are able to perform tasks that would normally require a human intelligence such as decision making, visual recognition, or speech recognition. However, human intelligence is a very ambiguous term. I believe there are three main attributes an artificial intelligence system has that makes it representative of human intelligence (Source 1). The first is problem solving, the ability to look ahead several steps in the decision making process and being able to choose the best solution (Source 1). The second is the representation of knowledge (Source 1). While knowledge is usually gained through experience or education, intelligent agents could very well possibly have a different form of knowledge. Access to the internet, the la...

    Decision trees: Tree-shaped structures that represent sets of decisions. These decisions generate rules for the classification of a dataset. Specific decision tree methods include Classification and Regression Trees (CART) and Chi Square Automatic Interaction Detection (CHAID). CART and CHAID are decision tree techniques used for classification of a dataset. They provide a set of rules that you can apply to a new (unclassified) dataset to predict which records will have a given outcome. CART segments a dataset by creating 2-way splits while CHAID segments using chi square tests to create multi-way splits. CART typically requires less data preparation than CHAID.

  • Essay On The History Of Artificial Intelligence

    824 Words  | 2 Pages

    It is a type of artificial intelligence program that imitated the analytical skills and understanding of human experts. By 1985, the artificial intelligence market had come up to one billion dollars; moreover, around the same time, Japan’s fifth generation computer project motivated the British and American government to bring back funding for artificial intelligence. Unfortunately, the artificial intelligence market fell back into disrepute which started with the fall of the Lisp Machine market. Additionally, this was a much longer “AI winter”. Soon, in the late 1900s and in the beginning of the 21st century, artificial intelligence was starting to be utilized for data mining, medical diagnosis, and in other areas as well as logistics. All this success was because of the increasing computational power, new relationships between other fields and artificial intelligence, higher significance on answering specific issues, and a commitment by researchers to scientific standards as well as mathematical methods. For example, on May 11th, 1997, Deep Blue (an IBM computer) was the first computer that played chess and it beat the ruling world chess champion at that time, Garry Kasparov. This was the beginning of an amazing discovery, artificial intelligence. Faster computers, able to obtain huge amounts of information, and statistical and advanced methods allowed progress in perception and machine learning. By the midyear of 2010, machine learning programs were utilized in the entire world. For example, Watson (IBM’s question answering system) beat Ken Jennings and Brad Rutter, the two greatest champions of Jeopardy, in a Jeopardy exhibition match by huge amounts. Another example is of the Kinect. It gives a 3D body-motion interface for the Xbox One and the Xbox 360 using algorithms that surfaced from long artificial research. Soon, 2015 came. According to

    Humans can expand their knowledge to adapt the changing environment. To do that they must “learn”. Learning can be simply defined as the acquisition of knowledge or skills through study, experience, or being taught. Although learning is an easy task for most of the people, to acquire new knowledge or skills from data is too hard and complicated for machines. Moreover, the intelligence level of a machine is directly relevant to its learning capability. The study of machine learning tries to deal with this complicated task. In other words, machine learning is the branch of artificial intelligence that tries to find an answer to this question: how to make computer learn?
