What is sentiment analysis? Using NLP and ML to extract meaning

#artificialintelligence

Sentiment analysis is analytical technique that uses statistics, natural language processing, and machine learning to determine the emotional meaning of communications. Companies use sentiment analysis to evaluate customer messages, call center interactions, online reviews, social media posts, and other content. Sentiment analysis can track changes in attitudes towards companies, products, or services, or individual features of those products or services. Get the latest insights with our CIO Daily newsletter. One of the most prominent examples of sentiment analysis on the Web today is the Hedonometer, a project of the University of Vermont's Computational Story Lab.

It opens the minds of readers about the applications of artificial intelligence in multiple industries across the world.


Automation is changing the rules for insurance underwriting - TechHQ

#artificialintelligence

The insurance industry is the very definition of risk-averse, and that includes the sector's critical operation of underwriting. Spend a working lifetime identifying, analyzing, quantifying and ascribing monetary value to risk, and one is likely to have a fairly strong aversion to undertaking new endeavors with inadequately understood consequences. For all the commentary suggesting otherwise, insurance still has an appetite for innovation. If the insurtech sector is any indication, then an interest in and requirement for new solutions is being recognized and addressed. It may not employ the language of disruption that runs through the wider fintech market, it may be short a few unicorns and unable to boast some of the record-breaking funding rounds, but a quiet tech revolution has been building in insurance nonetheless. Hence the advent of automated underwriting facilitated by artificial intelligence and advanced analytics (AI).


Five charts that reveal the geography of the AI economy

#artificialintelligence

Earlier this month, Brookings Metro published a data-driven snapshot of the growth and geography of the emerging artificial intelligence (AI) economy in the United States. Employing seven basic measures of AI research and commercial activity, the report benchmarked U.S. metropolitan areas on the basis of their core AI assets and capabilities as they stand now. Here, we look at the report's most important takeaways through five charts. The AI industry is growing rapidly, with AI-related projects accounting for a substantially larger share of federal research and development expenditures at U.S. colleges and universities. Similarly, newly founded firms that provide AI solutions of all tech startups expanded to more than 5%, from less than 1% a decade ago.


Could microscale concave interfaces help self-driving cars read road signs? – Physics World

#artificialintelligence

A structural colour technology that produces concentric rainbows could help autonomous vehicles read road signs, scientists in the US and China claim. As well as exploring the physics of these novel reflective surfaces, the researchers show that they can produce two different image signals at the same time. Autopilot systems that read both signals would be less likely to misinterpret altered road signs, they suggest. Car autopilot systems use infrared laser-based light detection and ranging (lidar) systems to scan their environment and recognize traffic situations. To read signs, autonomous vehicles rely on visible cameras and pattern recognition algorithms.

Source Code: A short film depicting artificial intelligence in a future war

#artificialintelligence

Please join the Atlantic Council's Scowcroft Center for Strategy and Security for the premiere screening of Source Code, a short film by Mark Kiefer depicting the interface of human and machine at war in 2065. The event will feature keynote remarks by futurist August Cole, author of Burn-In and Ghost Fleet, and will conclude with a panel discussion among Kiefer; author Jamie Metzl, from whose story, "A Visit to Weizenbaum," the film was adapted; and Tess deBlanc-Knowles, director of research and analysis at the National Security Commission on Artificial Intelligence (NSCAI). This latest installment in Forward Defense's Art of War project will take place on Wednesday, September 15, 2021 from 2:00 p.m. to 3:30 p.m. ET.

Artificial intelligence success is tied to ability to augment, not just automate

#artificialintelligence

Artificial intelligence is only a tool, but what a tool it is. It may be elevating our world into an era of enlightenment and productivity, or plunging us into a dark pit. To help achieve the former, and not the latter, it must be handled with a great deal of care and forethought. This is where technology leaders and practitioners need to step up and help pave the way, encouraging the use of AI to augment and amplify human capabilities. Those are some of the observations drawn from Stanford University's recently released report, the next installment out of its One-Hundred-Year Study on Artificial Intelligence, an extremely long-term effort to track and monitor AI as it progresses over the coming century.


Softmax function and Misconception

#artificialintelligence

Softmax is a mathematical function used to normalize the values between 0 and 1. In Deep Learning, Softmax is used as the activation function to normalize the output and scale each value in vector between 0 and 1. Softmax is used for classification tasks. At the last layer of the Network, an N-dimensional vector gets generated, one for each class in the Classification task. Softmax is used to normalize those weighted sum values between 0 and 1, and sum of them is equals to 1, that's why most people consider these values as Probabilities of classes but it is a Misconception we will discuss it in this article. Using this mathematical expression, we calculate normalized values for each class of data.
