Conversational AI: Design and Build a Contextual AI Assistant - DZone AI


Though conversational AI has been around since the 1960s, it's experiencing a renewed focus in recent years. While we're still in the early days of the design and development of intelligent conversational AI, Google quite rightly announced that we were moving from a mobile-first to an AI-first world, where we expect technology to be naturally conversational, thoughtfully contextual, and evolutionarily competent. In other words, we expect technology to learn and evolve. Most chatbots today can handle simple questions and respond with prebuilt responses based on rule-based conversation processing. For instance, if user says X, respond with Y; if user says Z, call a REST API, and so forth.

The limitations of artificial intelligence in cardiology


Artificial intelligence (#AI) seems to be all the rage these days, as it should be, given its potential to revolutionize medicine in many ways. Siri and Alexa use #AI too, so we can't easily escape it. Why would we want to? Of course, one concern about the algorithms is that they often are trained on ethnically homogenous datasets, potentially limiting their generalizability to the general population in the United States, and to others around the world. It is quite common for innovations in personalized medicine to be trained and validated in Caucasian populations, with the typical exclusion of minorities.

10 AI Apps for Android That Will Boost Your Productivity - Tech Business Guide %


For the business leader or entrepreneur, every day can seem like a battle. Phone calls, text messages, setting appointments, taking notes of conversations, attending meetings. Even prioritizing your email inbox seems like a daunting task. Wouldn't it be great if you could have a personal assistant who would take care of all that for you? Well, that is the promise of Artificial Intelligence Apps.

An AI Taught Itself to Solve a Rubik's Cube in 20 Moves


"Our AI takes about 20 moves, most of the time solving it in the minimum number of steps," Baldi says. "Right there, you can see the strategy is different, so my best guess is that the AI's form of reasoning is completely different from a human's." The ultimate goal of projects such as this one is to build the next generation of AI systems, Baldi says. Whether they know it or not, artificial intelligence touches people every day through apps such as Siri and Alexa and recommendation engines working behind the scenes of their favorite online services. "But these systems are not really intelligent; they're brittle, and you can easily break or fool them," Baldi says.

Rule Based System


Every rule based system contains four basic components. Firstly, the system contains a set of rules, also known as the rule base, and acts as the domain of knowledge for the computer. Second, there is an interference engine, also called the semantic reasoner. This component is responsible for interpretation of the rules and taking action accordingly. The interference engine works in three steps: match, conflict-resolution, and act.

Dominant Strategy Equilibrium. The Evolution Of Choice Under Uncertainty. Analyze & Golden rules.


Why Partnership Strategy, not Technology, drives Digital Transformation? Known from the 17th century (Blaise Pascal invoked it in his famous wager, which is contained in his Pensées, published in 1670), the idea of expected value is that, when faced with a number of actions, each of which could give rise to more than one possible outcome with different probabilities, the rational procedure is to identify all possible outcomes, determine their values (positive or negative) and the probabilities that will result from each course of action, and multiply the two to give an "expected value", or the average expectation for an outcome; the action to be chosen should be the one that gives rise to the highest total expected value. Decision theory (or the theory of choice) is closely related to the field of game theory and is an interdisciplinary topic, studied by economists, statisticians, psychologists, biologists, political and other social scientists, philosophers, and computer scientists. The need for decision under uncertainty has never been stronger. Although the digital realm is evolving fast, the partnership strategical choice remains a human prerogative and a key driver of the digital ecosystem evolution.

Computational Sustainability

Communications of the ACM

These are exciting times for computational sciences with the digital revolution permeating a variety of areas and radically transforming business, science, and our daily lives. The Internet and the World Wide Web, GPS, satellite communications, remote sensing, and smartphones are dramatically accelerating the pace of discovery, engendering globally connected networks of people and devices. The rise of practically relevant artificial intelligence (AI) is also playing an increasing part in this revolution, fostering e-commerce, social networks, personalized medicine, IBM Watson and AlphaGo, self-driving cars, and other groundbreaking transformations. Unfortunately, humanity is also facing tremendous challenges. Nearly a billion people still live below the international poverty line and human activities and climate change are threatening our planet and the livelihood of current and future generations. Moreover, the impact of computing and information technology has been uneven, mainly benefiting profitable sectors, with fewer societal and environmental benefits, further exacerbating inequalities and the destruction of our planet. Our vision is that computer scientists can and should play a key role in helping address societal and environmental challenges in pursuit of a sustainable future, while also advancing computer science as a discipline. For over a decade, we have been deeply engaged in computational research to address societal and environmental challenges, while nurturing the new field of Computational Sustainability.

On Being 'Random Enough'

Communications of the ACM

The concept of randomness is easy to grasp on an intuitive level but challenging to characterize in rigorous mathematical terms. In "Algorithmic Randomness" (May 2019), Rod Downey and Denis R. Hirschfeldt present a comprehensive discussion of this issue, incorporating the distinct perspectives of "statisticians, coders, and gamblers." Randomness is also a concern to "modelers" who depend on simulation models driven by random number generators or analytic models built using probabilistic assumptions. In such cases, the underlying mathematical model is often an ergodic stochastic process, and the issue is whether the output of the simulator's random number generator or the observed behavior of the real-world system being modeled is "random enough" to establish confidence in the model's predictions. In a sense, this highly pragmatic perspective represents a less restrictive approach to the issue of randomness: if any of the strong criteria described by the authors are satisfied, the output of the simulator's random number generator or the observed behavior of the system being modeled should be sufficiently random to establish confidence in a model's predictions.

Microsoft harvests unintentional audio in program that listens to Xbox users via Cortana and Kinect

Daily Mail - Science & tech

Microsoft's listening program continues to grow in scope after a new report reveals that contractors harvested unintentional audio from Xbox users through Cortana and the Kinect. Motherboard reports that Xbox users were recorded by Microsoft as part of a program to analyze users' voice-commands for accuracy and that those recordings were assessed by human contractors. While the program was designed to only scrape audio uttered after a wake-word, contractors hired by Microsoft report that some recordings were taken accidentally without provocation. The practice, reports Motherboard, has been ongoing for several years since the early days of Xbox One and predates Xbox's integration with its voice assistant, Cortana. Xbox users were being recorded by Microsoft in a listening program that scraped audio from Cortana and its augmented reality hardware, Kinect.

Combating Insurance Fraud With Machine Learning


Most insurance companies depend on human expertise and business rules-based software to protect themselves from fraud. And the drive for digital transformation and process automation means data and scenarios change faster than you can update the rules. Machine learning has the potential to allow insurers to move from the current state of "detect and react" to "predict and prevent." It excels at automating the process of taking large volumes of data, analysing multiple fraud indicators in parallel – which taken individually may often be quite normal – and finding potential fraud. Generally, there are two ways to teach or train a machine learning algorithm, which depend on the available data: supervised and unsupervised learning.
