The Benefits And Core Processes Of Data Wrangling

Data wrangling, also known as data munging, is the process of cleaning, transforming, and organizing raw data for further analysis and integration. In this article, I will explore the significance and benefits of data wrangling, the process of making raw data usable for different end users, and the application of data wrangling in AI and machine learning. Let’s start by taking a closer look at data wrangling and its significance in finance. With a predicted market size of 103B in 2027 according to Statista, unlocking big data’s full potential is more relevant than ever. As big data continues to evolve, companies…

Just Nine Out Of 116 AI Professionals In Key Films Are Women, Study Finds

Report says pattern seen in films such as Ex Machina risks contributing to lack of women in tech. A relentless stream of movies, from Iron Man to Ex Machina, has helped entrench systemic gender inequality in the artificial intelligence industry by portraying AI researchers almost exclusively as men, a study has found. The overwhelming predominance of men as leading AI researchers in movies has shaped public perceptions of the industry, the authors say, and risks contributing to a dramatic lack of women in the tech workforce. Beyond the impact on gender balance, the study raises concerns about the knock-on effects…

Here’s How Data Science Can Help Solve Global Crises

Global disruptions are growing more complex, taxing the capacities of social impact organizations and governments on the front lines. Innovative companies use data science to improve every aspect of their operations, but those sophisticated tools aren’t available to many organizations and governments. Companies, funders and global institutions together can help organizations and governments build a robust data science infrastructure, to navigate future crises more equitably. Across the world, local officials and NGO workers are heroically responding to overlapping, complex crises – whether they’re battling new waves of the COVID-19 pandemic or delivering aid after natural disasters. The energy and determination…

How AI Can Worsen Health Care Disparities?

Data sources that “teach” artificial intelligence could amplify and worsen disparities in health care, says law professor Nicholson Price. Those data sources are not representative and/or are based on data from current unequal care, says Price, a member of the University of Michigan’s Institute for Healthcare Policy & Innovation. In a recent article in Science, Price and colleagues Ana Bracic of Michigan State University and Shawneequa Callier of George Washington University say these disparities are happening despite efforts in medicine by physicians and health systems trying strategies focused on diverse workforce recruitment or implicit bias training. Here, Price answers questions about bias and AI in healthcare: Q What is an example of anti-minority culture? A…

Foundation Models: 5 Things To Know About The Hottest New Trend In AI

If you’ve seen photos of a teapot shaped like an avocado or read a well-written article that veers off on slightly weird tangents, you may have been exposed to a new trend in artificial intelligence (AI). Machine learning systems called DALL-E, GPT and PaLM are making a splash with their incredible ability to generate creative work. These systems are known as “foundation models” and are not all hype and party tricks. So how does this new approach to AI work? And will it be the end of human creativity and the start of a deep-fake nightmare? 1. What are foundation models? Foundation models work by training a single huge system on large…

Using Artificial Intelligence In Health Sciences Education Requires Interdisciplinary Collaboration And Risk Assessment

Over the past five years, there has been an increase in research and development related to the use of artificial intelligence (AI) in health sciences education in fields such as medicine, nursing and occupational therapy. AI-enhanced technologies have been shown to have educational value and offer flexibility for students. For example, learning scenarios can be repeated and completed remotely, and educational experiences can be standardized. However, AI’s applications in health sciences education need to be explored further. To better understand advances in research and applications of AI as a part of the education of health sciences students, we conducted a…

Artificial Intelligence’s Promise And Peril

AS ALGORITHMS ANALYZE MAMMOGRAMS AND SMARTPHONES CAPTURE LIVED EXPERIENCES, RESEARCHERS ARE DEBATING THE USE OF AI IN PUBLIC HEALTH. John Quackenbush was frustrated with Google. It was January 2020, and a team led by researchers from Google Health had just published a study in Nature about an artificial intelligence (AI) system they had developed to analyze mammograms for signs of breast cancer. The system didn’t just work, according to the study, it worked exceptionally well. When the team fed it two large sets of images to analyze—one from the UK and one from the U.S.—it reduced false positives by 1.2 and 5.7 percent and…
