Bayes’ theorem, also known as Bayes’ rule or Bayes’ law named after 18th-century British mathematician Thomas Bayes, is a mathematical formula used to calculate conditional probability. In other words, it is used to calculate the probability of an event based on its association with another event. It incorporates prior knowledge while calculating the probability of occurrence of the same in the future. It is often used in today’s highly demanding Machine Learning and Artificial Intelligence applications and is now one of the most useful concepts for understanding few Vantage algorithms to predict the probability of an outcome. So, let’s try to understand ... Read More

And it serves to remind us that even though we are all hunkered down in our safe spots, we are all in this together and must work as a group to get through this and be in a better place. I thought of that as I roamed the grocery store and stared at the rows and rows of empty shelves. This should not have happened. The problem was that panic set in and when that happens, people ...

Feed: Teradata Blog. On February 5, the number of confirmed COVID-19 cases jumped 45% when authorities included clinically diagnosed patients in Hubei province in China[1]. The reason for this uptick was largely publicized as a modification to national treatment guidelines, adding 13,332 cases to the confirmed list. In other words, until the use of more specific diagnostics through nucleic acid testing kits and CT scans, there was a large number of unconfirmed cases (patients that present but are not diagnosed) of the infection in Hubei, as their health systems were representing a large percentage of presumed positive cases as “Pneumonia” ...

Introduction What happens when a virus-based disease spreads stealthily across the world, at an alarming spread rate, without sight of it ending anytime soon? Relatively unheard of just a couple of months ago, the new coronavirus disease (COVID-19) that emerged from Wuhan has already triggered a global health emergency. This infection outbreak has since spread to more than 150 countries, affecting more than 170,000 cases, and resulting to more than 6,500 deaths.  Globally, the rate of infection has grown at such an alarming rate that many countries have already declared state of emergency, with those hardest hit declaring lockdowns ...

Answers and Outcomes More than 400 KPIs measure stc’s success against its DARE strategy. ‘Quality of Experience’ stands out as a key categorical measure of stc’s progress against its corporate strategy.  Creating a superior customer experience means stc’s customers become stickier, are willing to upgrade, accept a cross-sell, or upsell more frequently which drives stc loyalty. However, before stc can accelerate growth in their traditional business through upsell and cross-selling opportunities, they must ensure that customer experience is simplified to minimize customer disruptions, making stc easy to do business with. ‘Quality of Service’ starts with optimizing calls ...
