‘Anyone relying on lidar is doomed,’ Elon Musk says – TechCrunch

“LIDAR is a fool’s errand,” Elon Musk said.

“Anyone relying on LIDAR is doomed. Doomed! [They are] expensive sensors that are unnecessary. It’s like having a whole bunch of expensive appendices. Like, one appendix is bad, well now you have a whole bunch of them, it’s ridiculous, you’ll see.”

Not LIDAR like some of Tesla’s chief competitors.

Elon Musk previously explained that he views LIDAR as a crutch for self-driving vehicles.

For Tesla, cameras are the keys to the future and its CEO sees a future when cameras will enable Tesla to see through the most adverse weather situations.

The company today detailed its current generation self-driving computer that works with all existing Tesla vehicles.

Once the software is ready, it will enable all Teslas to drive autonomously with their existing sensor set – at least that’s what the company says – and that sensor set doesn’t include LIDAR..

This clever AI hid data from its creators to cheat at its appointed task – TechCrunch

The intention of the researchers was, as you might guess, to accelerate and improve the process of turning satellite imagery into Google’s famously accurate maps.

What tipped the team off was that, when the agent reconstructed aerial photographs from its street maps, there were lots of details that didn’t seem to be on the latter at all.

What the agent was actually being graded on was how close an aerial map was to the original, and the clarity of the street map.

The details of the aerial map are secretly written into the actual visual data of the street map: thousands of tiny changes in color that the human eye wouldn’t notice, but that the computer can easily detect.

The colorful maps in are a visualization of the slight differences the computer systematically introduced.

A computer creating its own steganographic method to evade having to actually learn to perform the task at hand is rather new.

As always, computers do exactly what they are asked, so you have to be very specific in what you ask them.
