‘Artificial intelligence may soon anticipate pandemics and disasters’


Scientists’ primary goal is to predict the size and timing of natural disasters. However, because they are statistically so uncommon, there is insufficient information to reliably anticipate them.

Academics from Brown University and the Massachusetts Institute of Technology say that artificial intelligence can now be used to predict them.

By combining efficient machine learning, which is an application of AI, and statistical algorithms, which require fewer data to produce accurate predictions, they were able to successfully avoid the requirement for enormous amounts of data in a recent study that was published in the journal Nature Computational Science.

In a university release, study author George Karniadakis, a Brown professor of applied mathematics and engineering, stated, “You have to realize that these are stochastic events.”

“We don’t have a lot of historical data because these are rare events like an outburst of a pandemic like COVID-19, an environmental disaster in the Gulf of Mexico, an earthquake, huge wildfires in California, a 30-meter wave that capssizes a ship,”

“To predict them further into the future, we lack sufficient samples from the past. The following is the topic of our paper: To reduce the number of data points required, what is the best data we can use?

The best approach, according to the team, was sequential sampling with active learning.

These algorithms can learn from the incoming data and study it to find additional data points that are just as important or more important. In other words, less knowledge can accomplish more.

The machine learning model they used is DeepOnet, a type of artificial neural network that mimics human brain neuronal connections by using stacked and interconnected nodes.

This tool processes data across both of these neural networks, combining their capabilities into one.

In the end, this makes it possible to examine enormous quantities of data in a very short amount of time while simultaneously producing enormous quantities of data in response.

By utilizing DeepOnet and dynamic learning draws near, the scientists had the option to show that even without a lot of information, they can dependably recognize cautioning indications of a devastating event.

Karniadakis explained that the objective is not to collect every piece of data and input it into the system but rather to actively search for occurrences that will signify the unusual events.

That’s what he added in spite of the fact that there may not be numerous instances of the genuine occasion, those forerunners could exist. They can be identified mathematically, and when paired with actual events, they will help this data-hungry operator learn.

The team even found that their method could outperform conventional models, and they agree that their framework could set a standard for more accurate predictions of unusual natural events.

They discovered that damaging waves that are more than twice the size of nearby waves can be predicted by looking at likely conditions over time. In the team’s article, they explain how scientists could budget for and forecast even more accurately for future experiments.
