An AI to save cats

Only 500 leopard wild cats survive in the almost urban jungle of Taiwan and are on the verge of extinction. In order to protect the endangered species, DT42, a Taiwan-based deep learning startup is using AI (in collaboration with Taiwan’s Directorate General of Highways) to “detect leopard cats when they near roads and keep them out of harm’s way, reducing roadkills.” Just a reminder that while we can fear AI, it can come in handy.

Details on Tesla’s new big beefy chips

Each Tesla computer has two AI chips, a redundant design for better safety, Venkataramanan said. There’s redundancy in the chips’ power supplies and data input feeds, too. Even the car’s cameras are on two separate power supplies to guard against failures. ….Each Tesla AI chip runs at 2GHz and performs 36 trillion operations per second. That performance is possible because Tesla optimized the chips for self-driving cars and dropped anything more general purpose…..For example, the chip handles data recorded as 8-bit integers instead of the 16-bit floating-point numbers more common in AI tasks but that require more power to process. For another, it’s got an extremely limited set of instructions it can process. And it’s got a gargantuan 32 megabytes of high-speed SRAM memory on the chip, which means it doesn’t have to wait around while fetching data from much slower conventional DRAM memory.

Apple has taught Silicon Valley the importance of owning its own chip destiny and now pretty much everyone willing to push the technical edge is building their own chips, for more vertical integration in their designs. Tesla gave a glimpse into how it can keep ahead of its deep pocketed rivals. At the Hot Chips conference, Tesla showed details on its newest innovation. The chip took 14 months to design and Samsung is going to make the processor. It is in newer Tesla cars. It is 21-times faster than the Nvidia chip they were using and about 80 percent of the cost.

What Did Tesla Do Now?

In many ways, Tesla — Elon Musk’s lightning rod of a car company — is the perfect allegory for modern Silicon Valley. The ongoing psychodrama of personalities drowns out the amazing technical achievements that are happening all around us. While the latter is what will ultimately determine our future, it’s the soap opera most of us can’t turn away from.

As usual, this has been a real “Dr. Jekyll and Mr. Hyde” kind of week for Tesla. It had a disastrous earnings report card, and Elon keeps creating all the wrong sorts of headlines. But in the middle of this maelstrom, the company announced a new chip that is going to eventually become the brain for their electric car. This chip is not just any chip — it will be able to make sense of a growing number of sensors that allow the car to become better and better at assisted (if not fully automated) driving.
