U.S. Judge Questions Trump Administration on Birth Control Rules

U.S. News

The contraception mandate was implemented as part of the 2010 Affordable Care Act, former Democratic President Barack Obama's signature healthcare legislation, popularly known as Obamacare. Republicans, who control the U.S. House of Representatives, Senate and White House, have so far failed to repeal the law, a top presidential campaign promise of Trump.


Latent Laplacian Maximum Entropy Discrimination for Detection of High-Utility Anomalies

arXiv.org Machine Learning

Anomaly detection is a very pervasive problem applicable to a variety of domains including network intrusion, fraud detection, and system failures. It is a crucial task in many applications because failure to detect anomalous activity could result in highly undesirable outcomes. For example, (i) detection of anomalous medical claims is important to identify fraud; (ii) detection of fraudulent credit card transactions is necessary to help prevent identity theft; and (iii) detection of abnormal network traffic is necessary to identify hacking. Many techniques have been developed for anomaly detection. These methods can be broadly classified into two categories: (i) rule-based systems, and (ii) statistical datadriven approaches. The rule-based systems are based on domain expertise and look for specific types of anomalies while the data-driven approaches look to identify anomalies by identifying statistically rare patterns. Examples of datadriven methods include parametric methods that assume a known family for the nominal (non-anomalous) distribution and nonparametric methods such as those using unsupervised or semi-supervised support vector machines (SVMs) [1], [2] or based on minimum volume set estimation [3], [4], [5]. The advantage of data-driven approaches over rule-based methods is that they can identify novel types of anomalies that are unknown to the domain expert.


Back off, Jeff Sessions. California and other states should be able to legalize and regulate pot on their own

Los Angeles Times

California voters decided last year that the sale of recreational marijuana should be made legal, beginning on Jan. 1, 2018. But Proposition 64 left many of the details to local governments and state regulators. So the last several months have been a race against the calendar, as officials have sought to develop rules governing where, when and how businesses may grow, transport and sell marijuana to adults. Last month, the state unveiled 276 pages of regulations for the new recreational pot marketplace. Among other things, the rules set hefty licensing fees, regulate how much THC will be allowed in edibles and other cannabis products, and require marijuana businesses to track their product from seed to sale.


Machine Learning or Linguistic Rules: Two Approaches to Building a Chatbot

#artificialintelligence

"It gets better over time" may be the leading slogan for artificial intelligence (AI) these days. Is "better later" acceptable in today's marketplace? How long should we wait for AI to become great? For a company that is trying to decide whether to use chatbots to serve customers, those questions matter. Because companies know that interactions are probably going to begin with a question, they need to program customer service chatbots to determine the intent of the message -- i.e., what it is the customer wants.


Years After Lehman: Final Rules Set on Strengthening Banks

U.S. News

The Basel committee rules have been an ongoing international response to the 2007-2009 financial crisis that saw the bankruptcy of U.S. investment bank Lehman Brothers and taxpayer bailouts of big banks. The financial crisis was the prelude to the Great Recession that saw many people lose their jobs and homes. Governments in the United States, Europe and elsewhere were pushed to rescue banks to prevent a cutoff of credit to businesses that would further harm the economy and increase unemployment.


Democratic AI in the Hybrid Cloud

#artificialintelligence

Sponsored You've got an application or workflow that needs to do lots of repetitive work typically done by people in the past. Or you want to branch out into some new area of digital business or customer experience. It might just be a perfect fit for an artificial intelligence algorithm, perhaps using a form of machine learning or a rules-based system. AI has been a long-promised concept but has been held back by, among other factors, a lack of the kinds of raw computer power required to process vast amounts of data and to crunch complex algorithms. It's only now, thanks to cloud, these resources are becoming available, as Intel and service providers make available this kind of power available through their massive server farms.


Intelligent EHRs: Predicting Procedure Codes From Diagnosis Codes

arXiv.org Machine Learning

In order to submit a claim to insurance companies, a doctor needs to code a patient encounter with both the diagnosis (ICDs) and procedures performed (CPTs) in an Electronic Health Record (EHR). Identifying and applying relevant procedures code is a cumbersome and time-consuming task as a doctor has to choose from around 13,000 procedure codes with no predefined one-to-one mapping. In this paper, we propose a state-of-the-art deep learning method for automatic and intelligent coding of procedures (CPTs) from the diagnosis codes (ICDs) entered by the doctor. Precisely, we cast the learning problem as a multi-label classification problem and use distributed representation to learn the input mapping of high-dimensional sparse ICDs codes. Our final model trained on 2.3 million claims is able to outperform existing rule-based probabilistic and association-rule mining based methods and has a recall of 90@3.


AI Will Change Organizations From Within

#artificialintelligence

Over the past year I've spoken formally and informally with hundreds of companies about their AI initiatives. The biggest AH-HA moment comes when these companies realize the difference between implementing traditional technology and applying analytics with adopting AI. AI is a change from within. New rules for AI are emerging that seem counter intuitive to those who are deeply rooted in today's analytics and rule based decisioning. AI learns by observing and understanding patterns, and optimizes based on continuous input and training. Instruction is not a set of rules, formulas and code.


Learning Certifiably Optimal Rule Lists for Categorical Data

arXiv.org Machine Learning

We present the design and implementation of a custom discrete optimization technique for building rule lists over a categorical feature space. Our algorithm produces rule lists with optimal training performance, according to the regularized empirical risk, with a certificate of optimality. By leveraging algorithmic bounds, efficient data structures, and computational reuse, we achieve several orders of magnitude speedup in time and a massive reduction of memory consumption. We demonstrate that our approach produces optimal rule lists on practical problems in seconds. Our results indicate that it is possible to construct optimal sparse rule lists that are approximately as accurate as the COMPAS proprietary risk prediction tool on data from Broward County, Florida, but that are completely interpretable. This framework is a novel alternative to CART and other decision tree methods for interpretable modeling.


North Dakota Rules Set for Use of Controversial Weed Killer

U.S. News

Monsanto has sued Arkansas over dicamba bans in that state, but a court battle doesn't appear likely in North Dakota. The company says it prefers to work with states and will urge North Dakota officials to be flexible on the cutoff date if conditions warrant.
