Active Measurement: Efficient Estimation at Scale

Hamilton, Max, Lai, Jinlin, Zhao, Wenlong, Maji, Subhransu, Sheldon, Daniel

arXiv.org Artificial Intelligence

AI has the potential to transform scientific discovery by analyzing vast datasets with little human effort. However, current workflows often do not provide the accuracy or statistical guarantees that are needed. We introduce active measurement, a human-in-the-loop AI framework for scientific measurement. An AI model is used to predict measurements for individual units, which are then sampled for human labeling using importance sampling. With each new set of human labels, the AI model is improved and an unbiased Monte Carlo estimate of the total measurement is refined. Active measurement can provide precise estimates even with an imperfect AI model, and requires little human effort when the AI model is very accurate. We derive novel estimators, weighting schemes, and confidence intervals, and show that active measurement reduces estimation error compared to alternatives in several measurement tasks.


World's largest carnivorous bats are big softies

Popular Science

Breakthroughs, discoveries, and DIY tips sent every weekday. As social flying mammals, bats typically live in colonies (or cauldrons) of up to 100 individual bats. While many species work together to forage, spectral bats (Vampyrum spectrum were previously believed to be more solitary when finding food. However, that may not be the case. Not only do they appear to forage in groups, they also display affectionate greetings to one another and provide food to feed their families.


Roblox, Discord, OpenAI and Google found new child safety group

Engadget

Roblox, Discord, OpenAI and Google are launching a nonprofit organization called ROOST, or Robust Open Online Safety Tools, which hopes "to build scalable, interoperable safety infrastructure suited for the AI era." The organization plans on providing free, open-source safety tools to public and private organizations to use on their own platforms, with a special focus on child safety to start. The press release announcing ROOST specifically calls out plans to offer "tools to detect, review, and report child sexual abuse material (CSAM)." Partner companies are providing funding for these tools, and the technical expertise to build them, too. The operating theory of ROOST is that access to generative AI is rapidly changing the online landscape, making the need for "reliable and accessible safety infrastructure" all the more urgent.


software technology park: Artificial Intelligence Rules The Roost In Modern Era: Expert

#artificialintelligence

Patna: The director of Software Technology Park of India, Subodh Sachchan, on Friday said artificial intelligence and machine learning have applications in different fields of learning right from primary to higher education and research. In fact, the modern era belongs to artificial intelligence (AI), he said. Addressing the webinar as the main speaker on'Artificial Intelligence And Machine Learning' organised by the Patna University-UGC Human Resource Development Centre for college and university teachers of the state, Sachchan pointed out that AI is no longer confined to science and engineering education only, but it is fast becoming almost indispensable for all branches of learning. Digital technology found its greatest applications in the field of education during Covid-19 AI can drive efficiency, personalization and streamline administrative tasks to allow teachers the time and freedom to provide understanding and adaptability. By leveraging the best attributes of machines and teachers, the vision for artificial intelligence is one where they work together for the best outcome for students, he said.


Artificial intelligence can help highway departments find bats roosting under bridges

AIHub

Photographs and computer vision techniques using artificial intelligence are able to detect the presence of bats on bridges automatically with over 90% accuracy, according to our new study. More than 40 species of bats are found in the U.S., and many of them are endangered or threatened. Bats often nest by the hundreds or thousands underneath bridges, so transportation departments are required to survey for them before conducting repair or replacement projects. I conducted the recently published study with colleagues at the University of Virginia's MOB Lab in collaboration with the Virginia Transportation Research Council. Bridge surveys are important for protecting threatened and endangered bat species. Guano, or excrement, droppings and stains are common signs that bats are present.

The chickens are coming home to roost in the smart home - Stacey on IoT Internet of Things news and analysis

#artificialintelligence

The smart home is dead. I'm not sure exactly when the time of death should have been called, but it happened at some point between Google trying to rebrand the smart home as "the helpful home" and the publication of this article, which expresses dismay that at five years of age, Amazon's Alexa offers little more than a new way of interacting with things, without deep functionality or truly new use cases. This week in New York, at an IoT Consortium event, I listened to executives of dozens of companies associated with the smart home talk around its death but never address the fact directly. Instead, they talked about a lack of compelling use cases, how to move beyond a device-specific mindset, and the ways they are trying to handle consumer demand for interoperability in the smart home without actually providing such interoperability. For example, Google's Mark Spates, who works in the smart display and speaker division, said onstage, "I don't think we've done a good job explaining our value proposition to consumers. We have to come up with new stories that isn't just'Go buy another Mini.'"


Drone blowback: High-tech weapons come home to roost

New Scientist

SHORTLY after 9/11, the US deployed a new form of high-tech warfare: sending drones into foreign airspace to kill terror suspects. At first the strikes were restricted to Afghanistan, but soon they were extended into Pakistan, Yemen and Somalia. The strategy has been escalated by presidents Obama and Trump. Initially the US had a virtual monopoly on drone technology, but commentators pointed out that this would only be temporary. Legal scholars also warned that the strikes were of dubious international legality. The implication was clear: if the US could strike with impunity, what was there to stop others from doing the same?


Researchers "Translate" Bat Talk. Turns Out, They Argue--A Lot

#artificialintelligence

Plenty of animals communicate with one another, at least in a general way--wolves howl to each other, birds sing and dance to attract mates and big cats mark their territory with urine. But researchers at Tel Aviv University recently discovered that when at least one species communicates, it gets very specific. Egyptian fruit bats, it turns out, aren't just making high pitched squeals when they gather together in their roosts. According to Ramin Skibba at Nature, neuroecologist Yossi Yovel and his colleagues recorded a group of 22 Egyptian fruit bats, Rousettus aegyptiacus, for 75 days. Using a modified machine learning algorithm originally designed for recognizing human voices, they fed 15,000 calls into the software.
