Sana Benefits gets $6.3 million to disrupt 'Stone Age' healthcare insurance industry

#artificialintelligence

Sana Benefits, an Austin company that wants to disrupt the healthcare insurance industry with more efficient software, said it has raised $6.3 million in seed funding. The company joins a raft of upstarts disrupting a notoriously inefficient healthcare system. These startups include players like Oscar Health, Clover, and Bright Health -- all of which have raised hundreds of millions to billions of dollars over the last few years. Most of them have been focused on individuals and not as much on the employer plans that cover half of Americans. Sana distinguishes itself in that it's one of the few new providers focused on providers, and specifically the market for small and medium sized businesses (a thousand or fewer employees).


An Active Approach for Model Interpretation

arXiv.org Artificial Intelligence

Model interpretation, or explanation of a machine learning classifier, aims to extract generalizable knowledge from a trained classifier into a human-understandable format, for various purposes such as model assessment, debugging and trust. From a computaional viewpoint, it is formulated as approximating the target classifier using a simpler interpretable model, such as rule models like a decision set/list/tree. Often, this approximation is handled as standard supervised learning and the only difference is that the labels are provided by the target classifier instead of ground truth. This paradigm is particularly popular because there exists a variety of well-studied supervised algorithms for learning an interpretable classifier. However, we argue that this paradigm is suboptimal for it does not utilize the unique property of the model interpretation problem, that is, the ability to generate synthetic instances and query the target classifier for their labels. We call this the active-query property, suggesting that we should consider model interpretation from an active learning perspective. Following this insight, we argue that the active-query property should be employed when designing a model interpretation algorithm, and that the generation of synthetic instances should be integrated seamlessly with the algorithm that learns the model interpretation. In this paper, we demonstrate that by doing so, it is possible to achieve more faithful interpretation with simpler model complexity. As a technical contribution, we present an active algorithm Active Decision Set Induction (ADS) to learn a decision set, a set of if-else rules, for model interpretation. ADS performs a local search over the space of all decision sets. In every iteration, ADS computes confidence intervals for the value of the objective function of all local actions and utilizes active-query to determine the best one.


How AI spots fraud quicker than people - Raconteur

#artificialintelligence

Identity fraud, in which a slice of your identity ranging from new credit cards to entire bank accounts is taken over by criminals, rose by 49 per cent in 2015 on the previous year. That totalled almost 170,000 cases, according to data collected by Cifas, the financial industry's non-profit fraud advisory service. The reason for the rise is that more and more we use the internet for financial transactions, but have very few ways to verify our identity without cumbersome systems involving human interaction, which are also vulnerable to fraud. Cifas' 2015 Fraudscape report shows that 86 per cent of identity fraud happened online, with bank accounts and credit or debit cards most targeted, closely followed by loans and communications, typically mobile phone accounts. Businesses looking to tackle fraud are turning to artificial intelligence and deploying neural networks because the systems learn in a manner like the brain's own neurons to try to bust fraud Traditionally, companies dealing with such problems have acted after the fact, trying to unravel complex or opportunistic frauds by working back through audit trails.


Introduction to Natural Language Processing (NLP) - KDnuggets

#artificialintelligence

NLP is an interdisciplinary field concerned with the interactions between computers and human natural languages (e.g: English) -- speech or text. Okay, now we get it, NLP plays a major role in our daily computer interactions, let's see more business-related NLP use-cases: NLP is divided into two fields: Linguistics and Computer Science. The Linguistics side is concerned with language, it's formation, syntax, meaning, different kind of phrases (noun or verb) and whatnot. The Computer Science side is concerned with applying linguistic knowledge, by transforming it into computer programs with the help of sub-fields such as Artificial Intelligence (Machine Learning & Deep Learning). Scientific advancements in NLP can be divided into 3 categories (Rule-based systems, Classical Machine Learning models and Deep Learning models).

How to adapt your production lines recipe in real time with AI to guarantee the highest quality

#artificialintelligence

This variation of production quality often depends on the heterogenous nature of the raw materials, even in the same batch, and in variables that cannot be controlled by the operators, such as the exterior temperature, the humidity, etc. Still, can't we do anything when rule-based systems and classic engineering cannot compensate in real time for these conditions? "To obtain a constant high quality, companies can either invent new predefined recipes, or must dynamically change the existing recipe", analyzes Jean-Philippe Hugo, CEO of Wizata. "Nowadays, recipes are highly complex and traditional methods aren't enough to stay ahead of the competition: your engineers and operators need to be assisted by a new set of eyes, powered by an artificial intelligence that takes advantage of the predictive power in the data to know in advance the final product quality, and how to select the optimal parameters to achieve a better result."

Rule-based Anomaly Detection: This is already framed by specific set of rules that describe an anomaly and assigns the thresholds and limits. We typically rely on the experience of industry experts whose findings are ideal to detect known anomalies. These anomalies are familiar anomalies to us and we can easily recognize, whether it is normal or abnormal. One of the major flaws of rule-based systems is that they don't detect anomalies automatically as patterns change. To learn new patterns, a new model would have to be built each time.
