MORS

"While conventional recommendation algorithms usually prioritize optimizing a single objective, it is now evident that considering additional metrics is crucial for improving the overall user experience. 

"Despite the importance of considering multiple objectives, conventional recommendation models face the challenge of balancing these objectives, which can sometimes conflict with each other. To tackle this challenge, there is a growing interest in multi-objective recommender systems (MORS) that consider multiple objectives simultaneously and provide a more personalized and varied set of recommendations. 

"MORS can optimize recommendations based on various metrics, including accuracy, diversity, novelty, and user satisfaction, leading to more efficient and personalized recommendation systems. 

"The objective of this paper is to conduct a systematic review study to assess the current state of research in the field of MORS and identify potential avenues for future exploration. 

"The study selection procedure includes 78 primary studies published from 2019 to January 2023. These preliminary studies are categorized based on different variables to address the research questions outlined in this study. 

"The findings of this systematic review study reveal a diverse range of applications, objectives, datasets, methodologies, and evaluation metrics utilized in the field of MORS."

The year-old search engine , whose founders previously worked in A.I. research at OpenAI and Meta, has quickly become one of the most buzzed-about products in the tech world. Tech insiders rave about it on social media, and investors like Jeff Bezos — who was also an early investor in Google — have showered it with cash. The company recently announced that it had raised $74 million in a funding round led by Institutional Venture Partners, which valued the company at $520 million. Many start-ups have tried and failed to challenge Google over the years. (One would-be competitor, Neeva, shut down last year after failing to gain traction.)  But Google seems less invincible these days.   Many users have complained that their Google search results have gotten clogged with spammy, low-quality websites, and some people have started looking for answers in places like Reddit and TikTok instead.

"Although a nuclear confrontation based on fake intelligence may seem unlikely, the stakes during crises are high and timelines are short, creating situations where fake data could well tilt the balance toward nuclear war. "The evolution of nuclear systems has led to further ambiguity in crises and shorter timeframes for verifying intelligence. An intercontinental ballistic missile from Russia could reach the U.S. within 25 minutes. A submarine-launched ballistic missile could arrive even sooner.  "Many modern missiles carry ambiguous payloads, making it unclear whether they are nuclear-tipped. AI tools for verifying the authenticity of content are not sufficiently reliable, making this ambiguity difficult to resolve in a short window. "The likeliest nuclear hotspots are also the arenas involving actors with low levels of trust on both sides — be that the U.S. and the Chinese Communist Party or Russia, or India and Pakistan. Even if communication is established in a...
