The current world speed record for riding a bike down a straight, flat road was set in 2012 by a Dutch team, but the Swiss have a plan to topple their rivals — with a little help from machine learning. An algorithm trained on aerodynamics could streamline their bike, perhaps cutting air resistance by enough to set a new record.
Currently the record is held by Sebastiaan Bowier, who in 2012 set a record of 133.78 km/h, or just over 83 mph. It’s hard to imagine how his bike, which looked more like a tiny landbound rocket than any kind of bicycle, could be significantly improved on.
But every little bit counts when records are measured down a hundredth of a unit, and anyway, who knows but that some strange new shape might totally change the game?
To pursue this, researchers at the École Polytechnique Fédérale de Lausanne’s Computer Vision Laboratory developed a machine learning algorithm that, trained on 3D shapes and their aerodynamic qualities, “learns to develop an intuition about the laws of physics,” as the university’s Pierre Baqué said.
“The standard machine learning algorithms we use to work with in our lab take images as input,” he explained in …read more
