MIT developing AI tool to predict flooding with realistic satellite images

JACKSONVILLE, Fla. – Scientists at MIT are creating a synthetic intelligence (AI) instrument that generates life like satellite tv for pc photos for example potential flooding situations.

Based on Space.com, the instrument combines a generative AI mannequin with a physics-based flood mannequin to establish areas liable to flooding.

It then creates detailed chook’s-eye views of what the area may appear to be after a flood, based mostly on the depth of an approaching storm.

Nevertheless, GANs (Generative Adversarial Networks) generally produce “hallucinations,” that are options in photos which will seem life like however are inaccurate or shouldn’t be current.

“Hallucinations can mislead viewers. We had been contemplating how we might use these generative AI fashions in a climate-impact context, the place having dependable information sources is important. That is the place the physics mannequin comes into play,” mentioned Lütjens.

“The thought is, at some point, we might use this earlier than a hurricane, the place it supplies an extra visualization layer for the general public,” Björn Lütjens, a postdoc within the Division of Earth, Atmospheric, and Planetary Sciences on the Massachusetts Institute of Know-how (MIT), mentioned in a statement.

“One of many largest challenges is encouraging folks to evacuate when they’re in danger,” Lütjens mentioned. “Perhaps this could possibly be one other visualization to assist improve that readiness.”

To reveal the mannequin, the researchers utilized it to a state of affairs in Houston, producing satellite tv for pc photos of flooding within the metropolis after a storm related in power to Hurricane Harvey.

They in contrast the AI-generated photos to precise satellite tv for pc photos and to pictures created with out the help of the physics-based flood mannequin.

The AI photos generated with out the physics mannequin had been extremely inaccurate, that includes quite a few “hallucinations,” primarily exhibiting flooding in areas the place it wouldn’t be doable.

In distinction, the pictures produced utilizing the physics-reinforced technique carefully matched the real-world state of affairs.

The scientists envision that this expertise can be helpful for predicting future flooding situations.

It can present dependable visuals that may assist policymakers put together for and make knowledgeable choices about flood planning, evacuation, and mitigation efforts.

Of their press launch, the scientists famous that policymakers usually assess potential flood areas utilizing visualizations, typically color-coded maps.

“The query is: Can visualizations of satellite tv for pc imagery add one other degree to this that is a little more tangible and emotionally partaking than a color-coded map of reds, yellows, and blues whereas nonetheless being reliable?” Lütjens mentioned.

At present, the staff’s technique is within the proof-of-concept stage and requires extra time to investigate different areas to foretell the outcomes of assorted storms extra precisely.

“We present a tangible method to mix machine studying with physics for a use case that’s risk-sensitive, which requires us to investigate the complexity of Earth’s programs and venture future actions and doable situations to maintain folks out of hurt’s manner.” Dava Newman, professor of AeroAstro and director of the MIT Media Lab mentioned. ”We will’t wait to get our generative AI instruments into the palms of decision-makers at the local people degree, which might make a major distinction and maybe save lives.”
