Scientists exploring computers that can learn and adapt like a brain

For six or seven decades, computers have been based on processing electronic 1s and 0s. Now, computer scientists are breaking out of that paradigm in strange new directions, as they seek new ways to tackle problems that digital computers can’t easily solve.

 
One approach is quantum computing, in which the computer takes advantage of the ambiguous, “quantum” states of matter. After years of being mostly hypothetical quantum computing is edging into the real world: One startup, D-Wave, is building quantum computers that, it hopes, can determine a variety of possible solutions simultaneously and save energy by speeding up the computing process by many orders of magnitude. That could be useful for cryptography, among other applications.
 
Another approach is neuromorphic processing, in which circuits are wired together in a manner similar to the way neurons in the human brain connect to each other. As a neuromorphic processor evaluates a problem, it weights connections based on the results of its analysis, enabling the whole complex to “learn” in the same way human brains learn. This technology, and the Stanford researchers exploring it, is the subject of a New York Times story today.
 
The promise is that computers will some day be able to use this technology to improve their abilities at things like speech and image recognition, which humans excel at but computers, until lately, have not done so well at. 
 
Computer scientists have worked with “neural networks,” which are written in software and run on traditional silicon chips, for decades. The technology has advanced in recent years, and last year a Google neural network scanned a database of 10 million images and taught itself to recognize cats.

I found that machine learning has tremendous relevance for "big data” and could be applied to finding patterns among enormous and often heterogeneous data sets. Reply

Recently, it was reported that graphene flakes could advance quantum computing. They demonstrated spin-selective behavior that could ultimately lead to the creation of quantum computers. So, the field looks promising Reply

El-Hamalawy is particularly critical of Muslim groups for breaking an agreement between the secular organisers of the demonstration and the Islamic leadership. Parties to the agreement included the Gamaa Islamiya, Salafi Nour Party and the Muslim Brotherhood. El-Hamalawy explains, “An agreement was announced yesterday whereby the Islamists vowed not to include the application of Sharia on the list of their demands and not to attack or provoke any secular protesters. In exchange, the leftist and liberal groups agreed not to engage in the “Elections First” or “Constitution First” debate and promised not to chant against SCAF.” He goes on to argue that the Muslim groups, “wit Reply
