One-to-one customer engagement enabled by machine learning yields a 13 percent reduction in bounce rate and a 33 percent average order value improvement at Marmot. A recent study from Gallup shed light on just how valuable it is to invest in customer engagement. Fully engaged customers, defined as those who have had a measurable reaction, connection, or experience with your brand, represent a 23 percent share of wallet, profitability, revenue, and relationship growth premium compared to average shoppers. By contrast, the study found that disengaged customers -- those who have no emotional connection to your brand -- represent a 13 percent discount in those same measures. It's no surprise that customer engagement and loyalty applications have been hot in retail, particularly e-commerce, where customer data is easier to gather and easier to analyze than in any other channel.

Least squares regression can cause impossible estimates such as probabilities that are less than zero and greater than 1.So, when the predicted value is measured as a probability, use Logistic Regression We use the log of the odds rather than the odds directly because an odds ratio cannot be a negative number--but its log can be negative. Notice that we have randomly initialized our coefficients for income and other predictors. These will be adjusted by Solver based on a likelihood function.We will cover them later Column H tells us the predicted probability of the borrower's actual behavior, whether that behavior is repayment or default--not simply, as in Column G, the predicted probability of defaulting on the loan. One property of logarithms is that their sum equals the logarithm of the product of the numbers on which they're based The logarithms of probabilities are always negative numbers, but the closer a probability is to 1.0, the closer its logarithm is to 0.0. I haven't covered cross-validation, which is commonly used to validate a logistic regression equation.If you don't always have a large number of cases to work with, a different approach is to use statistical inference.

Brain–computer interfaces (BCIs) have traditionally been used to enable communication and control for paralyzed patients.1 However, it is also thought that BCIs hold promise for fulfilling the longstanding goal of creating artificial systems (i.e., which can perform with the adaptability, robustness, and general intelligence of humans). To augment the sensing and processing capabilities of such artificial systems, BCI systems can thus be used on healthy individuals. In this way, the biological machinery that enables human cognition can be leveraged. Image triage--a visual target search over a set of images--is a prime application for this new class of BCI.

Some economists are also worried future economies will consist of low-skilled jobs that are not profitable to automate and high-skilled jobs that complement new technologies. The losers will be a widening swathe of middle-skilled workers. Because the trajectory of future technology is unpredictable, the exact impact on jobs is rather unclear. A much cited study by researchers at Oxford University found that 47pc of jobs in the US could become automated in the next 20 years. Yet a recent OECD paper* found (more plausibly, in this columnist's view) that 9pc of jobs at highrisk of being automated. The figure for Ireland was even lower, at 8pc.

Scientists with the international scientific collaboration known as the "Walk Again Project" use noninvasive brain-machine interfaces in their efforts to reawaken damaged fibers in the spinal cord. Scientists with the international scientific collaboration known as the "Walk Again Project" use noninvasive brain-machine interfaces in their efforts to reawaken damaged fibers in the spinal cord. Researchers in Brazil who are trying to help people with spine injuries gain mobility have made a surprising discovery: Injured people doing brain training while interacting with robot-like machines were able to regain some sensation and movement. The findings, published in Scientific Reports (one of the Nature journals), suggest that damaged spinal tissue in some people with paraplegia can be retrained to a certain extent -- somewhat the way certain people can regain some brain function following stroke though repetition and practice. Even people with severe injuries can regain some sensation and function through physical therapy if some nerve fibers remain.

British actor Kenny Baker, who starred as R2-D2 in six Star Wars films, has died aged 81 after a long illness, his niece has confirmed. Baker made his name as the robot in the first Star Wars film in 1977 alongside Anthony Daniels's C-3PO character. Star Wars creator George Lucas paid tribute to a "real gentleman" and Mark Hamill - Luke Skywalker in the films - said he had lost "a lifelong friend". Born in Birmingham, Baker's other films include Time Bandits and Flash Gordon. After starring in the original Star Wars film he went on to appear in the sequels, The Empire Strikes Back and Return of the Jedi, and the three prequels between 1999 and 2005.

Airships, which are distinct from blimps by being much more rigid and sounding much less silly, are one of those unusual technologies that has been undergoing a resurgence recently after falling out of favor half a century ago. Airships have potential to be a very practical and cost effective way to move massive amounts of stuff from one place to another place, especially if the another place is low on infrastructure and has a reasonable amount of patience. Lockheed Martin's Skunk Works has been developing a particular kind of airship called a hybrid airship, which uses a combination of aerodynamics and lifting gas to get airborne, for the last decade or so. The P-791 technology demonstrator first flew in 2006, and a company called Hybrid Enterprises is taking Lockheed's airship technology to commercialization. Their LMH-1 will be able to carry over 20,000 kilograms of whatever you want, along with 19 passengers, up to 2,500 kilometers, and it's going to be a real thing: Hybrid Airships recently closed a US 480 million contract to built 12 of them for cargo delivery.

Scientists and engineers led by Duke University neuroscientist Miguel A. Nicolelis report that a group of spinal-cord-injury patients who trained to walk using a brain computer interface (BCI) in combination with an Occulus Rift virtual reality device and with a robotic exoskeleton have regained the ability to voluntarily move their leg muscles and to feel touch and pain in their paralyzed limbs. The study, the results of 12 months of training, is the first long-term BCI experiment to show significant recovery from such severe injuries, the researchers say. The researchers reported their results today in the journal Scientific Reports. A non-invasive electroencephelogram-based brain computer interface was central to the therapies. During the virtual reality excercises, patients were told to imagine walking through a virtual scene.

Digital transformation in marketing is simply the application of information and technology to bolster marketer's performance. The marketing technology landscape has exploded in the past 3 years, with 323 marketing tech startups fetching over 11 billion from venture capitalists in 2015 alone. The unprecedented growth in marketing technology landscape is overshadowed by the massive growth of information and business related data production and consumption. We are in the age of the customer, where everyone is mobile, social, data driven and almost always connected. According to Pew 2016 research, 1 in 5 U.S. adults (50 million) are almost always online.
