This week’s list of data news highlights covers August 2-8 and includes articles about a computer model to predict supreme court decisions and a collaboration between two major health insurers to create a data exchange system.
A team of scholars has developed a computer model that forecasts U.S. Supreme Court decisions with 70 percent accuracy. The model was built from data on 7,700 cases and more than 68,000 justice votes. The model takes into account information on the case’s topic, what lower court it originated in, and other data. In the future, the model’s creators hope to pit it against human predictors to improve its accuracy and possibly deploy similar models for lower courts.
Insurers Blue Shield of California and Wellpoint Inc.’s Anthem Blue Cross announced this week that they would collaborate on a health information exchange covering about nine million plan members. The initiative, called California Integrated Data Exchange, will be an independent nonprofit organization that gives participating doctors and hospitals access to the trove of information in exchange for sharing their own patients’ records. California’s top health official said she would be willing to explore the possibility of including information from the state’s Medicaid participants in the exchange in the future.
This week, IBM researchers detailed a new computer processor that is inspired by the architecture of the brain. The processor, called TrueNorth, manipulates information using an interconnected network of transistors that behave like neurons. Its creators hope their device, which is about as complex as a bee’s brain, will lend itself to artificial intelligence applications.
A connected baby activity tracker from San Francisco-based startup Sproutling is now available for pre-order. The tracker, which uses sensors to measure babies’ heart rate, temperature, mood, and position while they sleep, comes with a mobile app from which parents can monitor their children remotely and get alerts if something is wrong. The company is also hoping parents will let the company anonymously share their babies’ data, both to improve Sproutling’s models but also to contribute to research in the field of neonatal health.
The Florida Department of Children and Families (DCF) is hoping to use predictive analytics to reduce child abuse risk. Earlier this year, the DCF released a report determining key risk factors for child fatalities and concluded that the agency should develop a child welfare analytics system that incorporates a wider set of data. Some suggestions for data to include in the predictive models include information on financial hardship, substance abuse in the family, or household members with a history of violence.
General Electric (GE) is using Internet of Things sensors to gather data on its factory floors and optimize its production. The sensors collect granular information on temperature and humidity conditions, machine performance, and product quality. In June, the company announced it would commit $400 million to build a “brilliant factory” in which machine parts report information continuously and operators can predictively schedule maintenance before anything breaks. The efforts are part of an initiative the company calls “the industrial Internet,” for which it set aside $1 billion in funding in 2011.
Researchers from MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct sounds from vibrations in objects. Specifically, they set out to recover intelligible speech from tiny vibrations in objects—such as a potato chip bag, a cup of water, and the leaves of a potted plant—that were filmed through soundproof glass. The algorithm’s creators hope it can one day be applied in law enforcement and forensics contexts.
Data software company Splunk launched its eRegulations Insights Project this week to sort through all the public comments left on government filing repository regulations.gov. The company has found a number of insights so far, including the fact that a third of the public comments made since 2012 focused on three issues: the Affordable Care Act, the Keystone Pipeline, and political contributions from nonprofits. The recently released FCC Open Internet comments were not included in the project, as they are housed on a separate system.
The UK’s second-highest court ruled this week that individuals seeking government data through freedom of information requests have a choice of file format. The case, in which a Buckinghamshire man fought a protracted battle with that city for student test results data, hinged on provisions in the country’s freedom of information laws that let requesters specify whether they wanted the information in hard copy or electronic format. The judge found that the provisions naturally extend themselves to electronic file formats.
Music streaming company Spotify is using deep learning, a branch of machine learning inspired by neurons in the brain, to improve its song recommendation algorithms. Deep learning is helping Spotify analyze the acoustic content of songs in order to recommend music that sounds similar to what its users already like, rather than simply recommending songs that listeners with similar taste have liked. The company also hopes this approach will help it filter out sonic mismatches from its current recommendations.
