Predicative analytics, a statistical or data mining approach that determines outcomes using a series of algorithms and techniques used on both structured and unstructured data, has become a technology high in demand. Although not a new method, its ease of use, inexpensive computing power and organizations increasing amounts of data have driven its adoption.
The technology is being used for retention analysis, fraud detection, medical diagnosis and risk assessment, to name a few. Fern Halper, director of research for advanced analytics at TDWI, highlighted four trends about predicative analytics in a blog post on TDWI website.
Techniques: Although the top three predicative analytics techniques are linear regression, decision trees and clustering, others have become more widely used. These include time series data analysis, which can be applied to weather observations, stock market prices, and machine-generated data; machine learning, which can uncover previously unknown patterns in data; and ensemble modeling, in which predictions from a group of models are used to generate more accurate results.
Open source: Open source solutions enable a wide community to engage in innovation. The R language, a free software environment for data manipulation, statistics and graphics has become one of the most popular open source solutions addressing predicative analytics in the enterprise.
In-memory analytics: In-memory analytics processes data in random-access memory rather than on disk, which lets users to analyze large data sets more effectively.
Predictive analytics in the cloud: The use of the public cloud for analytics appears to be increasing. Organizations are starting to investigate the cloud for business intelligence, and users are putting their big data in the cloud where so can process real-time data as well as running predictive models on extremely large multisource data sets.

The National Atlas of the United States and the National Map will be combined into a single source for geospatial and cartographic information, the U.S. Geological Survey announced.
The purpose of the merger is to streamline access to information from the USGS National Geospatial Program, which will help set priorities for its civilian mapping role and “consolidate core investments,” the USGS said.
The National Atlas provides a map-like view of the geospatial and geostatistical collected for the United States. It was designed to “enhance and extend our geographic knowledge and understanding and to foster national self-awareness,” according to its website. It will be removed from service on Sept. 30, 2014, as part of the conversion. Some of the products and services from the National Atlas will continue to be available from The National Map, while others will not, the agency said. A National Atlas transition page is online and will be updated with the latest news on the continuation or disposition of National Atlas products and services.
The National Map is designed to improve and deliver topographic information for the United States. It has been used for scientific analysis and emergency response, according to the USGS website.
In an effort to make the transition an easy one, the agency said it would post updates to the National Map and National Atlas websites during the conversion, including the “availability of the products and services currently delivered by nationalatlas.gov.”
“We recognize how important it is for citizens to have access to the cartographic and geographic information of our nation, said National Geospatial Program Director Mark DeMulder. “We are committed to providing that access through nationalmap.gov.”

Apple introduced its iBeacon at a developers conference last June, an “indoor positioning system” it described as "a new class of low-powered, low-cost transmitters that can notify nearby iOS 7 devices of their presence."
Like other beacons, Apple’s iBeacon works in the Bluetooth Low Energy frequency range to send notifications to other devices within a network of “location-aware” beacons mounted on nearby surfaces.
While the technology is new, initial interest has focused on applications in the retail, events or energy savings, but the technology has also spawned ideas for applications in the public-sector community. In a blog on the National Center for State Courts website, court technology consultant Jim McMillan proposed several, including apps for courthouse navigation and public safety.
“It would be great to be able to provide an automatic guide to assist the public in what is called ‘wayfaring’ though a courthouse facility,” McMillan wrote. Or a courtroom beacon system could be set up to locate over-scheduled attorneys trying to keep up with the typical delays and sudden shifts in the docket.
Finally, beacons could help tighten courthouse security, wrote McMillan, “by automatically locating and calling the closest bailiffs or deputies to the courtroom if there is a problem that they could address.”
For other location-aware applications of beacon technology, “our imagination is the only limit,” he said.

Survey: 2013 Data Governance Survey Results, by Rand Secure Data
Key Points: In spite of the fact that organizations expect overall data growth in the next year between 26 percent and 50 percent, with the median amount of data stored between 20TB to 50TB, respondents reported that their data management tools (archiving, backup and ediscovery) don’t meet expectations.
Only 8 percent of organizations with more than 500 TB of data rated their data archiving solutions as excellent, and over 32 percent of respondents overall ranked their data and email archiving solutions as average or poor. The more data an organization has, the lower the solutions were ranked.
Of the 98 percent of respondents who said they have backup solutions in place, 25 percent of them said they were extremely satisfied with their current solution, while just under 40 percent said they are or may be looking to implement or upgrade their backup solution within the next year. Nearly 15 percent more of survey respondents however indicated archiving is more important than backup to their organizations.
Nearly 20 percent of respondents reported they do not have an ediscovery solution in their organization, while only 10 percent with a solution rated it as excellent. Over one quarter rated their solution as poor, and more than half (51 percent) are or may be looking to upgrade their solution in the next year.
Bottom line: The dissatisfaction over data and email archiving systems combined with their importance within organizations signify a need in the market for new and innovative data and email archiving solutions.

The Department of Homeland Security is rolling out a plan to offer states and territorial government organizations a set of free managed security services, including intrusion detection and prevention, netflow analysis and firewall monitoring.
The services will be provided by the Center for Internet Security’s Multistate Information Sharing and Analysis Center (MS-ISAC), a 24x7 operations center that provides real-time network monitoring, threat warnings and incident mitigation and response.
The plan is part of a multipronged effort to boost government threat information sharing and cooperation called for in the National Institute of Standards and Technology’s Cybersecurity Framework, a set of voluntary guidelines released by NIST in February to promote the protection of critical systems and management of cybersecurity risk.
Phyllis Schneck, DHS deputy undersecretary for cybersecurity for the National Protection and Programs Directorate (NPPD), said making the managed services available and adopting the NIST framework a key step making local government information systems secure.
“The adoption of the framework will encourage longer term risk-based planning and better security overall – this is a win-win and we are excited to be able to provide such tactical assistance to our state and territorial stakeholders,” she said in a recent blog post.
To help promote the use of the NIST framework and coordinate projects to strengthen information sharing, DHS this February launched the Critical Infrastructure Cyber Community (C3) Voluntary Program, which will help coordinate critical infrastructure operations, DHS said.
In its first year, the C3 Voluntary Program will focus on engaging with “sector-specific agencies,” including the defense industrial base, energy and emergency services sectors to adopt the NIST framework.
Later phases of the program will “reach out to all critical infrastructure (groups) interested in using the framework,” according to DHS.
The C3 program will also encourage the critical infrastructure community to “manage cybersecurity as part of an ‘all hazards approach’ to enterprise risk management,” according to DHS.
