Coursera Inc. (/ k ər ˈ s ɛ r ə /) is an American global massive open online course provider. It was founded in 2012 [2] [3] by Stanford University computer science professors Andrew Ng and Daphne Koller. [4] Coursera works with universities and other organizations to offer online courses, certifications, and degrees in a variety of subjects.
In 2011, Ng founded the Google Brain project at Google, which developed large-scale artificial neural networks using Google's distributed computing infrastructure. [44] Among its notable results was a neural network trained using deep learning algorithms on 16,000 CPU cores , which learned to recognize cats after watching only YouTube videos ...
Google Answers' predecessor was Google Questions and Answers, which was launched in June 2001. This service involved Google staffers answering questions by e-mail for a flat fee (US$3.00). It was fully functional for about 24 hours, after which it was shut down, possibly due to excessive demand and the tough competition that Yahoo! set in place ...
For many years, sequence modelling and generation was done by using plain recurrent neural networks (RNNs). A well-cited early example was the Elman network (1990). In theory, the information from one token can propagate arbitrarily far down the sequence, but in practice the vanishing-gradient problem leaves the model's state at the end of a long sentence without precise, extractable ...
On the other hand, a problem is AI-Hard if and only if there is an AI-Complete problem that is polynomial time Turing-reducible to . This also gives as a consequence the existence of AI-Easy problems, that are solvable in polynomial time by a deterministic Turing machine with an oracle for some problem.
In addition, Google’s Network News Transfer Protocol (NNTP) server and associated peering will no longer be available, meaning Google will not support serving new Usenet content or exchanging content with other NNTP servers. This change will not impact any non-Usenet content on Google Groups, including all user and organization-created groups.
is the message ">" sent to 3 with argument 4 (the answer of which will be false). The programmer is free to define new binary selectors just as they are free to define novel unary and keyword messages. Notice, that the Smalltalk-80 language itself does not imply the meaning of those operators.
Updates to the standard are planned to occur biannually. [28]Version 1.0 of the specification was published on 4 October 2022. [29] It introduced support for lighting products (such as mains power plugs, electric lights and switches), door locks, thermostats and heating, ventilation, and air conditioning controllers, blinds and shades, home security sensors (such as door, window and motion ...
