IBM Plans To Create Chips That Work Like the Human Brain

August 2011, by 

IBM announced Thursday that it has received $21 million in funding  Advanced Research Projects Agency (DARPA) to develop a series of experimental computer chips designed to replicate the human brain’s perceptive, active and cognitive abilities.

According to IBM, the “neurosynaptic” chips “recreate the phenomena between spiking neurons and synapses in biological systems, such as the brain, through advanced algorithms and silicon circuitry” — meaning that they can be used to build complex, multi-sensory learning systems (“cognitive computers”) that behave more like human brains than calculators.

These computers will be able to learn through experiences, detect patterns and develop hypotheses, as well as remember and learn from the outcomes.

IBM and its partners even think the computers will be able to rival the brain’s compact size and relatively low power usage. The team’s long-term goal is to build a system with 10 billion neurons and 100 trillion synapses that is less than two liters in volume and consumes merely one kilowatt of power. To do so, they’ll need to abandon traditional Von Neumann architecture in favor of more efficient architecture that does away with set programming and integrates memory and processors.

The chips will be particularly advantageous in processing and reacting to information from multiple sensory modes in real time. IBM describes two potential use cases, one in which a system monitoring the world’s water supply could record and report metrics such as temperature, pressure, wave height, acoustics and ocean tide, and issue tsunami warnings based on its decision making; and another in which a grocer stocking shelves could use an instrumented glove that monitors sights, smells, texture and temperature to flag bad or contaminated produce.

“This is a major initiative to move beyond the von Neumann paradigm that has been ruling computer architecture for more than half a century,” observes Dharmendra Modha, project leader for IBM Research. “Future applications of computing will increasingly demand functionality that is not efficiently delivered by the traditional architecture. These chips are another significant step in the evolution of computers from calculators to learning systems.”

    Hello Web Admin, I noticed that your On-Page SEO is not that great, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you? That’s right AUTOMATICALLY, just watch this 4minute video for more information at. WordPress Seo Plugin
