The traditional public transit system may no longer be the most efficient or cost-effective option for suburban commuters. According to a group of researchers at Concordia University, the solution lies in the implementation of On-Demand Transit (ODT). This innovative approach, outlined in a paper published in the journal Transportation Research Record, replaces the traditional bus
In the world of computer science, bipartite matching is a well-known problem that arises in various scenarios such as rideshare apps, organ donor matching, and ad placements. This task involves pairing two sets of elements in a way that maximizes overall satisfaction. Associate Professor Saket Navlakha from Cold Spring Harbor Laboratory has delved into this
As companies like Microsoft and Google continue to develop generative AI tools such as ChatGPT, the promise of saving time and money is undeniable. However, the issue of models “hallucinating” or inventing answers poses a significant challenge. According to Vik Singh, a Microsoft vice president, the key missing element is the ability of AI models
The recent blocking of social media platform X in Brazil has sparked controversy and division among users and politicians regarding the legitimacy of the ban.
