Eclipsing the Competition: The Solar PV Industry Simulation | LearningEdge at MIT Sloan
Mit learning edge simulation dating. The Massachusetts Institute of Technology's (MIT) Sloan School of Management's LearningEdge offers. The basic idea—that software can simulate the neocortex's large array of neurons write software that is familiar with the attributes of, say, an edge or a sound. Management simulation games create a virtual world for students to explore business issues. Experience real-world lessons with MIT Sloan's LearningEdge.
Google also used the technology to cut the error rate on speech recognition in its latest Android mobile software.

In October, Microsoft chief research officer Rick Rashid wowed attendees at a lecture in China with a demonstration of speech software that transcribed his spoken words into English text with an error rate of 7 percent, translated them into Chinese-language text, and then simulated his own voice uttering them in Mandarin. That same month, a team of three graduate students and two professors won a contest held by Merck to identify molecules that could lead to new drugs.
The group used deep learning to zero in on the molecules most likely to bind to their targets. Google in particular has become a magnet for deep learning and related AI talent.

In March the company bought a startup cofounded by Geoffrey Hinton, a University of Toronto computer science professor who was part of the team that won the Merck contest. All this has normally cautious AI researchers hopeful that intelligent machines may finally escape the pages of science fiction. Indeed, machine intelligence is starting to transform everything from communications and computing to medicine, manufacturing, and transportation.
Microsoft has deployed deep learning in its Windows Phone and Bing voice search. Extending deep learning into applications beyond speech and image recognition will require more conceptual and software breakthroughs, not to mention many more advances in processing power. One has been to feed computers with information and rules about the world, which required programmers to laboriously write software that is familiar with the attributes of, say, an edge or a sound.
That took lots of time and still left the systems unable to deal with ambiguous data; they were limited to narrow, controlled applications such as phone menu systems that ask you to make queries by saying specific words.
Neural networks, developed in the s not long after the dawn of AI research, looked promising because they attempted to simulate the way the brain worked, though in greatly simplified form. These weights determine how each simulated neuron responds—with a mathematical output between 0 and 1—to a digitized feature such as an edge or a shade of blue in an image, or a particular energy level at one frequency in a phoneme, the individual unit of sound in spoken syllables.
Programmers would train a neural network to detect an object or phoneme by blitzing the network with digitized versions of images containing those objects or sound waves containing those phonemes.
This is much the same way a child learns what a dog is by noticing the details of head shape, behavior, and the like in furry, barking animals that other people call dogs. But early neural networks could simulate only a very limited number of neurons at once, so they could not recognize patterns of great complexity. They languished through the s. But the technique still required heavy human involvement: And complex speech or image recognition required more computer power than was then available.
InHinton developed a more efficient way to teach individual layers of neurons.
The first layer learns primitive features, like an edge in an image or the tiniest unit of speech sound. It does this by finding combinations of digitized pixels or sound waves that occur more often than they should by chance.
The process is repeated in successive layers until the system can reliably recognize phonemes or objects.
Design and Model with LiveLink™ for Solid Edge®
Last June, Google demonstrated one of the largest neural networks yet, with more than a billion connections. One simulated neuron in the software model fixated on images of cats. Others focused on human faces, yellow flowers, and other objects.
And thanks to the power of deep learning, the system identified these discrete objects even though no humans had ever defined or labeled them. What stunned some AI experts, though, was the magnitude of improvement in image recognition. That might not sound impressive, but it was 70 percent better than previous methods. And, Dean notes, there were 22, categories to choose from; correctly slotting objects into some of them required, for example, distinguishing between two similar varieties of skate fish.
Will you win customers and become cash flow positive before you run out of funds? Will you succeed and take your firm public?
John Sterman In this live web-based simulation, participants play the role of senior management at SunPower, a leading firm in the solar photovoltaic industry. The game simulates the solar PV industry as described in the SunPower case study. Users compete against other firms, simulated by the computer, and set the industry conditions so as to learn about strategy under different conditions relating to learning, knowledge spillovers, and competitor behavior.
Dennis Meadows, John Sterman and Andrew King Fishbanks is a multiplayer web-based simulation in which participants play the role of fishers and seek to maximize their net worth as they compete against other players and deal with variations in fish stocks and their catch.
Participants buy, sell, and build ships; decide where to fish; and negotiate with one another. Policy options available to instructors include auctions of new boats, permits, and quotas. Os participantes compram, vendem e encomendam barcos, decidem onde pescar e negociam entre si.
