Why Does PayPal Care What People Think About Apple?

Why Does PayPal Care What People Think About Apple? | Data Nerd's Corner | Scoop.it
From the moment Apple revealed its mobile wallet to the world, PayPal has wasted little opportunity to take its share of digs at the product.
Carla Gentry CSPO's insight:

If Apple Pay works as advertised, benefiting from the perceived security of Touch ID, it could finally win many consumers over to mobile payments. But it's up to consumers to decide whether to forgive Apple for iCloud's role in the celebrity photo leaks. If PayPal is the more trustworthy service, it should go without saying.

This brings the round total up to $444 million, as the Palo Alto, Calif.-based company appears to have held multiples closes since late last year. The most recent filings were this past February, which showed around $390 million raised. Some news reports suggested the round was being sold by placement agent Morgan Stanley with a $9 billion valuation.

Medical Calculators Use Big Data to Help Patients Make Choices

Medical Calculators Use Big Data to Help Patients Make Choices | Data Nerd's Corner | Scoop.it
Doctors are turning to clinical calculators that crunch big data to help patients make informed medical decisions. Cleveland Clinic's Michael Kattan has developed so-called "nomograms" that use statistical modeling to tailor predictions to individual patients.
Carla Gentry CSPO's insight:

But that one-size-fits-all approach doesn't take into account a patient's unique characteristics, such as age, gender, race, extent and type of disease and other health factors, says Michael Kattan, chairman of the department of quantitative health sciences at Cleveland Clinic's Lerner Research Institute. So doctors are turning to increasingly sophisticated calculators that can combine all these unique characteristics, compare them with the vast databases of similar cases and studies, and use them to predict probable outcomes depending on the treatment a patient chooses.

Carla Gentry CSPO's insight:

 It is why we can empathize and mourn a tragedy that hits home while mocking and cheering an AC-130 blasting away insurgents. It is also why we are able to remain surprisingly ambivalent to things that should shock us a great deal – drone strikes that kill innocents, renegade soldiers murdering entire families in Afghanistan, or labeling the deaths of dozens of Palestinian children by Israeli missiles simply collateral damage.

But all this changed with Google, which served as a role model for how data science research could not only be better conducted, but also how specific kinds of data could be more efficiently collected, understood and used to help businesses, says Howard. In particular, the company developed a software technique for processing huge troves of data called MapReduce, which broke tasks into many smaller components to perform among multiple machines,” says Kenneth Cukier, Data Editor for The Economist.

Carla Gentry CSPO's insight:

This kind of limitless data-mining is possible because most sites, including OkCupid, have use policies that give them unfettered rights to harness users’ details for research and product improvement.

Google’s search engine makes it wonderfully easy to locate stuff on the web, whether it’s in a news article, a corporate website, or a video on YouTube.

There are a few other Dremel clones out there already, such as Cloudera’s Impala and MapR’s Drill. But these other projects are more concerned with collecting data, says Madsen, while Quest is focused on manipulating data. “Data in its raw form isn’t that useful,” he says. “You have to do things to it. You have to shape, and discard the stuff you don’t need.”

Human Interaction: the Missing Link Between Big Data, Devices & Apps - A Smarter Planet Blog

Human Interaction: the Missing Link Between Big Data, Devices & Apps - A Smarter Planet Blog | Data Nerd's Corner | Scoop.it
By Kevin Parent I’ve devoted my career to telling stories with technology. Part of that decades-long work has focused on improving the ways in which humans interact with machines. Along the way, two things have become clear. First, the things that computers and humans are good at are complementary, not duplicative. While machines are steadily …
Carla Gentry CSPO's insight:

Attempts to integrate disparate systems have invariably been resource-intensive, prone to failure and non-scalable to new applications. Relying on analysts to retrieve data introduces lag time between question and response. Analytics programs and dashboards provide information that’s valuable, but can be narrow in scope.

But it doesn’t have to be this way. Instead using technology to generate ever-more overwhelming amounts of data, new technologies can help people use data in a way that is much more like telling a story than running a regression.

Using Data Science Techniques for the Automatic Clustering of IT Alerts | Pivotal P.O.V. | Data Nerd's Corner | Scoop.it
Carla Gentry CSPO's insight:

Insights such as these are useful for setting up alert review policies and can help automate response prioritization. Operationalizing the categorization of alerts enables their automatic routing to the right support person. In addition, root cause analysis and failure prediction use cases can also benefit from signals from these alert clusters.

While broad class labels of alerts may be available, often they are too general to be useful. So how can we use data science to achieve finer categorization of alerts?

Semi-structured text alerts are generated by IT infrastructure components such as storage devices, network devices, servers, etc. For the client-facing data science engagement I detail in this post, we leveraged only the textual information. To cluster the text data, the following steps were performed:

Our business is not based on having information about you. You're not our product. Our product are these, and this watch, and Macs, and so forth. And so we run a very different company. I think everyone has to ask, how do companies make their money? Follow the money. And if they're making money mainly by collecting gobs of personal data, I think you have a right to be worried. And you should really understand what's happening to that data, and the companies — I think — should be very transparent.

E-commerce is growing around the world. In fact, global online purchase intention rates doubled—in some cases tripled—between 2011 and 2014 across more than half of 22 categories measured by Nielsen. But not all age groups are shopping online to the same degree.

Guest: The slide toward an impulse society, thanks to big data and Amazon.com | Data Nerd's Corner | Scoop.it
Thoughtful consumerism isn’t so easy these days — in many ways, it’s getting harder as the marketplace gets better at targeting what shoppers want, writes guest columnist Paul Roberts.
Carla Gentry CSPO's insight:

But that cynicism is itself, in essence, a part of the marketing that we can reject. Consumers can push back against those bottom-line values and restore values that support the real, long-term needs of our communities and our citizens. Sure, the consumer marketplace will keep trying to make it easier to think small and short-term to undermine our own interests. (Imagine the sky filled with delivery drones.) But we can choose a different outcome. We can resist the click.

What is Data Science – Again?

What is Data Science – Again? | Data Nerd's Corner | Scoop.it
A look at some disparate definitions of data science
Carla Gentry CSPO's insight:

In his not-to-be-missed blog, Schutt's adviser at Columbia, noted statistician Andrew Gelman, is even more unabashed in chronicling differences between data science and statistics. “There’s so much that goes on with data that is about computing, not statistics. I do think it would be fair to consider statistics (which includes sampling, experimental design, and data collection as well as data analysis (which itself includes model building, visualization, and model checking as well as inference)) as a subset of data science.....The question then arises: why do descriptions of data science focus so strongly on statistical tasks? (As Schutt and O’Neil write, “the media often describes data science in a way that makes it sound like as if it’s simply statistics or machine learning in the context of the tech industry.”) I think it’s because statistics is the fun part and the part that, in this context, is new. The tech industry has always had to deal with databases and coding; that stuff is a necessity. The statistical part of data science is more of an option. To put it another way: you can do tech without statistics but you can’t do it without coding and databases.” A second Gelman blog, Statistics is the least important part of data science, reiterates these points.
