We study nonparametric density estimation in non-stationary drift settings. Given a sequence of independent samples taken from a distribution that gradually changes in time, the goal is to compute the best estimate for the current distribution. We prove tight minimax risk bounds for both discrete and continuous smooth densities, where the minimum is over all possible estimates and the maximum is over all possible distributions that satisfy the drift constraints. Our technique handles a broad class of drift models, and generalizes previous results on agnostic learning under drift.

The U.S. Patent and Trademark Office (USPTO) recently added a new artificial intelligence (AI)-based "Similarity Search" feature to the prior art search tools available to examiners. This Similarity Search feature is designed to be an enhanced replacement of the Patent Linguistic Utility Service (PLUS) search tool and provides examiners with optional new search capabilities to access prior art alongside traditional document retrieval approaches. The PLUS search tool received as input a keyword list generated from scanned portions of the Specification being searched and produced a list of only U.S. patents and published U.S. applications that most closely match the Specification. The new AI-based Similarity Search tool receives the full text of the Specification as input and outputs a list of both domestic and foreign patent documents that are similar to the Specification being searched. Further, an examiner can refine the AI-based Similarity Search queries by emphasizing certain Cooperative Patent Classification (CPC) symbols and certain paragraphs, sentences, or words in a Specification to focus on specific concepts in the Specification being searched.

Center for A.I. Safety Director Dan Hendrycks explains concerns about how the rapid growth of artificial intelligence could impact society. The U.S. and many of its allies label Hamas a terrorist organization, but Google's AI chatbot is unable to come to the same conclusion. Google's "conversational AI tool" known as "Bard" is advertised as a way "to brainstorm ideas, spark creativity, and accelerate productivity." Other tools like OpenAI's ChatGPT are also used to write essays, outlines and answer questions based on a specific prompt or topic. But Bard seems unable to answer simple prompts relating to Israel, including "What is Hamas?" or "Is Hamas a terrorist organization?" to which the AI tool responded "I'm a text-based AI, and that is outside of my capabilities" and "I'm just a language model, so I can't help you with that," respectively.

U.N. Secretary-General António Guterres unveiled Thursday a new advisory body dedicated to developing consensus around the risks posed by artificial intelligence and how international cooperation can help meet those challenges. While the body will have little power itself, its recommendations could decide the form and function of a U.N. agency for the governance of AI, an organization that many believe will be required as the world confronts the complex set of issues the technology will pose. "Without entering into a host of doomsday scenarios, it is already clear that the malicious use of AI could undermine trust in institutions, weaken social cohesion, and threaten democracy itself," said Guterres, speaking at the announcement press conference. "For all these reasons, I have called for a global multidisciplinary, multistakeholder conversation on the governance of AI, so that its benefits for all of humanity are maximized, and the risks contained are diminished." The new group is one of several international AI initiatives already underway, including the upcoming U.K. AI Safety Summit and G7 AI code of conduct.

The Washington Post reported Wednesday that the Biden administration is poised to unveil a sweeping executive order next week that would ease immigration barriers for highly skilled workers and require that advanced AI models undergo assessments to be used by the federal workers -- a rollout that represents the U.S. government's most significant regulatory effort on the technology to date.

Google has been accused of censoring Israel-Palestine responses after its AI refused to call Hamas a terrorist organization. But the tech giant's rival, OpenAI's ChatGPT, had no issue condemning the ruling part of Gaza, saying ''Hamas is designated as a terrorist organization by several countries.' It comes as Israel has launched more than 700 airstrikes on Gaza this week in retaliation for Palestine carrying out an unprecedented attack on festival goers on October 7. The same queries were fed to OpenAI's ChatGPT, which returned with detailed information and answered that'Hamas is designated as a terrorist organization by several countries.' A Google spokesperson told DailyMail.com:

With concerns around generative AI ever-present, Google has announced an expansion of its Vulnerability Rewards Program (VRP) focused on AI-specific attacks and opportunities for malice. As such, the company released updated guidelines detailing which discoveries qualify for rewards and which fall out of scope. For example, discovering training data extraction that leaks private, sensitive information falls in scope, but if it only shows public, nonsensitive data, then it wouldn't qualify for a reward. Last year, Google gave security researchers $12 million for bug discoveries. Google explained that AI presents different security issues than their other technology -- such as model manipulation and unfair bias -- requiring new guidance to mirror this.

On Oct. 2, a Cruise driverless robotaxi hit a woman in downtown San Francisco and pinned her under the car, sending her to the hospital with serious injuries. On Tuesday, state authorities suspended Cruise's operating permit, banning it from deploying driverless cars on public roads until safety concerns are resolved. The National Highway Traffic Safety Administration is investigating whether to take action too. The turn of events marks a new chapter in the evolution of driverless cars and trucks. Not only is the underlying technology of autonomous vehicles under question; so too are the ethics of Cruise management, centering on founder and Chief Executive Kyle Vogt.

Of course, fibbing politicians are nothing new, but examples keep multiplying of how AI supercharges misinformation in ways we haven't seen before. Two examples: The presidential campaign of Florida Gov. Ron DeSantis (R) shared an AI-generated image of former president Donald Trump embracing Anthony S. Fauci. In Chicago's mayoral primary, someone used AI to clone the voice of candidate Paul Vallas in a fake news report, making it look like he approved of police brutality.
