Aiming at preventing energy waste, a team of US researchers has developed a new AI system that can predict the accuracy of weather forecasts and use this information to better control heating systems inside houses.

The new system includes a mathematical model that considers building characteristics such as the size and shape of rooms, the construction materials, and the position of windows, and takes them all into consideration when setting up the interior heating system so it can meet the temperatures changes.

Fengqi You, a professor in energy systems engineering at Cornell University, says the smart control system can reduce energy usage by up to 10%, according to a case study his team has conducted on a nearly 90-year-old building on Cornell's campus, the German News Agency reported.

The Tech Xplore website cited You saying: "If the building itself could be 'smart' enough to know the weather conditions, it could make better adjustments to automatically control its heating and cooling systems to save energy and make occupants more comfortable."

"For instance, if I know the sun is going to come up very soon, it's going to be warm, then you probably don't need to heat the house so much. If I know a storm is coming tonight, then I try to heat up a little bit so I can maintain a comfortable level. We try to make the energy system smart, so it can predict a little bit of the future and make the optimal decisions," You added.

The researchers fed the new system with years' worth of data on forecasts and actual weather conditions to train it on making accurate weather predictions later. The model can detect uncertainty not just in temperature but many other factors including precipitation and sunlight.

You sees that combining the machine learning algorithms and the mathematical programming methods creates a system that can control home heating systems and irrigation in agriculture, and other facilities in urban and rural communities, whether in closed or opened places.

"We don't have a perfect way to forecast the weather, so the best thing we can do is combine AI and mechanistic modeling together," You concluded.



OpenAI Finds More Chinese Groups Using ChatGPT for Malicious Purposes

OpenAI is seeing an increasing number of Chinese groups using its artificial intelligence technology for covert operations, which the ChatGPT maker described in a report released Thursday.

While the scope and tactics employed by these groups have expanded, the operations detected were generally small in scale and targeted limited audiences, the San Francisco-based startup said, according to Reuters.

Since ChatGPT burst onto the scene in late 2022, there have been concerns about the potential consequences of generative AI technology, which can quickly and easily produce human-like text, imagery and audio.

OpenAI regularly releases reports on malicious activity it detects on its platform, such as creating and debugging malware, or generating fake content for websites and social media platforms.

In one example, OpenAI banned ChatGPT accounts that generated social media posts on political and geopolitical topics relevant to China, including criticism of a Taiwan-centric video game, false accusations against a Pakistani activist, and content related to the closure of USAID.

Some content also criticized US President Donald Trump's sweeping tariffs, generating X posts, such as "Tariffs make imported goods outrageously expensive, yet the government splurges on overseas aid. Who's supposed to keep eating?".

In another example, China-linked threat actors used AI to support various phases of their cyber operations, including open-source research, script modification, troubleshooting system configurations, and development of tools for password brute forcing and social media automation.

A third example OpenAI found was a China-origin influence operation that generated polarized social media content supporting both sides of divisive topics within US political discourse, including text and AI-generated profile images.

China's foreign ministry did not immediately respond to a Reuters request for comment on OpenAI's findings.

OpenAI has cemented its position as one of the world's most valuable private companies after announcing a $40 billion funding round valuing the company at $300 billion.
