Big design problems require creative and exploratory decision making, a skill in which humans excel.

When engineers use artificial intelligence (AI), they have traditionally applied it to a problem within a defined set of rules rather than having it generally follow human strategies to create something new.

The findings were published in the -- ASME Journal of Mechanical Design.

This research considers an AI framework that learns human design strategies through observation of human data to generate new designs without explicit goal information, bias, or guidance.

The study was co-authored by Jonathan Cagan, professor of mechanical engineering and interim dean of Carnegie Mellon University’s College of Engineering.

And, Ayush Raina, a PhD candidate in mechanical engineering at Carnegie Mellon, and Chris McComb, an assistant professor of engineering design at the Pennsylvania State University.

“The AI is not just mimicking or regurgitating solutions that already exist,” said Cagan. “It’s learning how people solve a specific type of problem and creating new design solutions from scratch.” How good can AI be? “The answer is quite good.”

The study focuses on truss problems because they represent complex engineering design challenges.

Commonly seen in bridges, a truss is an assembly of rods forming a complete structure.

The AI agents were trained to observe the progression in design modification sequences that had been followed in creating a truss based on the same visual information that engineers use -- pixels on a screen -- but without further context.

When it was the agents’ turn to design, they imagined design progressions that were similar to those used by humans and then generated design moves to realise them.

The researchers emphasised visualisation in the process because vision is an integral part of how humans perceive the world and go about solving problems.

The framework was made up of multiple deep neural networks which worked together in a prediction-based situation.

Using a neural network, the AI looked through a set of five sequential images and predicted the next design using the information it gathered from these images.

“We were trying to have the agents create designs similar to how humans do it, imitating the process they use: how they look at the design, how they take the next action and then create a new design, step by step,” said Raina.
