TECH SPECIAL......................... COMPUTERS AS HUMANS


COMPUTERS AS HUMANS 

The next wave of computing will be about applications that are as intuitive and capable as human beings. And IBM and a few startups are providing the platform for this explosive opportunity


    In a few months from now, or at least sometime next year, a few IBM partners will release a series of software products that will be unlike anything people have encountered so far. Instead of doing a task for you through a software program, these products will prepare you instead to do that task yourself. You could ask the computer about your health, a home purchase, or a travel plan. You don’t need visits from sales executives for product briefings. The computer will gently guide you to make the right choice at the right time.
Currently, these products are being built around Watson, the famous IBM computer that won the Jeopardy championship. To be precise, it is built around a more compact and powerful machine than the Jeopardy champion. IBM threw open this machine to programmers on the cloud three weeks ago to build products and services in a few industries to begin with. IBM has applications from 200 potential partners, including a few from India, focused initially on healthcare, financial services and travel. “We are trying to build an ecosystem of partners around Watson,” says Jay Subrahmonia, vice-president of development and delivery, Watson Solutions at IBM.
IBM calls it cognitive computing, to distinguish it from the more common term, artificial intelligence. It is purportedly the next wave of computing, infinitely more powerful and long-lasting than any other computing wave we have seen. It changes the way we interact with computers, the reason we use computers, and also the way we program computers. It is a big business opportunity as well. Just the global healthcare market for such systems is projected to increase from $201 million now to $239 billion by 2019, according to the market research firm WinterGreen Research.
Next Computing Wave
Computers that we use now are fast but dumb. Those in the cognitive computing era will understand the context in which they function. They will also learn constantly and improve their capabilities. Yet, they won’t be based on any single technology, as the current examples show. The core of Watson is based on natural language processing (NLP), or the ability to understand human languages. But it combines this ability with massive computing resources and a host of other computing technologies like machine learning, information retrieval and automated reasoning. Other companies—many based in the Silicon Valley—are building different solutions based on different technologies. Grok, a recent startup from Palm Pilot founder Jeff Hawkins, mimics the human brain to predict anomalies in IT systems. Palantir Technologies, based in Palo Alto, uses cognitive analytics to predict suspicious or terrorist activities. ColdLight, based in a small town in Pennsylvania, uses machine learning to examine thousands of factors simultaneously, usually to identify fraud. All of them, and hundreds of similar companies, are part of the coming cognitive computing wave. The common theme: understanding data. In some ways, they are an extension of the current wave of analytics and big data companies, but there are some differences. Traditional analytics requires a human being to ask a question. In cognitive computing, we get the answers without knowing what to ask. Deloitte estimates the US cognitive computing market will expand in five years from the current $1 billion to $50 billion. “Growth usually takes place through labour and capital,” says Rajeev Ronanki, lead for Deloitte’s cognitive computing practice. “Here it is related to machine learning algorithms.” This difference can make the cognitive computing market grow rapidly. “Traditional approaches are like giving the computing system a fish,” says Ronanki, “whereas cognitive systems are akin to teaching a computer how to fish.” This can cause a fundamental shift with how markets grow. For IBM, taking Watson to the cloud was a nobrainer. Its current price is not known, but it is considered too expensive as a standalone system. The hardware cost alone of the machine that won Jeopardy was $3 million, but Watson contains plenty of algorithms and data as well. Putting it on the cloud would enable companies to pay as they use it. Watson is also complex for even the brighte s t o f p ro g r a m m e r s. A n Ap p l i c at i o n Programming Interface (API) on the cloud would substantially simplify the task of programming, as the programmer would not need to understand what is inside the box.
When Computers Talk, See...
So far, Watson has been used mainly to solve problems in healthcare. At the Memorial Sloan-Kettering Cancer Center in New York, Watson goes through millions of pages of cancer data and recommends the best treatment options for patients. The sports goods company North Face uses Watson to provide customers recommendations for the ideal gear for a trip. Over the next year, Watson will seep into more industries as developers make applications on the cloud.
IBM says that Watson will be among its fastestgrowing business ever. In the near future, analysts expect Watson to drive the cognitive computing industry as well. Yet the arena is busy with startups, some of whom claim to have developed breakthrough technologies. Take Grok. It came out of a project called Numenta started by Jeff Hawkins. Numenta is supposed to have cracked how the b r a i n wo rk s ; i t s Cortical Lear ning Algorithm is modelled on the neocortex, the part of the brain involved in higher functions like reasoning, thought and language. Grok was spun off this year from Numenta, which is now an open source project to advance the technology.
Grok’s first product—in Beta stage—is to detect anomalies in IT systems and prevent problems before they become manifest. Current products to detect anomalies look for patterns exceeding a threshold. It is hard, if not impossible, to detect anomalies below this threshold, which is usually the case at night, when few people use the systems. Grok tries to solve this problem combining three methods: learning online by itself, creating models automatically, and recognising patterns. “Our models learn continuously,” says Craig Vaughn, vicepresident of marketing and products at Grok. “They keep changing as IT policies change.”
This ability to learn is at the heart of any cognitive computing system, and distinguishes it from traditional analytics. It is relevant wherever there is a fast data stream: retail, healthcare, travel, telecom. But not if the data stream consists of images—computers cannot understand images. This is why robots are so unreliable. “If robots could understand the world,” says Dileep George, founder of Vicarious, “the benefits could be enormous.” For example, we could have sent them inside the Fukushima reactor to fix it.
Vicarious, near San Francisco, is among the many companies trying to make computers see. George, an IIT graduate, has funding from top VCs like Peter Thiel. It had a breakthrough recently; it cracked the Captcha, a set of overlapping and contorted letters that humans can recognise easily but computers find impossible to read. Vicarious created an algorithm that can separate the overlapping letters with a high degree of accuracy. It is a good step towards making computers understand the environment around them. But there is a long way to go.
How is it Being Applied
Cancer treatment
Memorial Sloan-Kettering Cancer Center in New York is training IBM’s Watson to absorb millions of pages of cancer-research results, and use it to recommend ways of treatment
Online shopping
Fluid, an online shopping technology firm, is using Watson to enhance customer shopping experience, by holding a conversation with them and making recommendations
