Indian Origin Team Develops Model For Safer Self-driving Cars

"When the system is deployed into the real world, it can use learned model to act more cautiously and intelligently," said Ramakrishnan

A team of Indian American researchers has developed a novel model that uses human inputs to uncover Artificial Intelligence (AI) “blind spots” in self-driving cars, so that the vehicles can avoid dangerous errors in the real world.

The model developed by MIT and Microsoft researchers identifies instances in which autonomous systems have “learned” from training examples that don’t match what’s actually happening in the real world.

Engineers could use this model to improve the safety of AI systems, such as driverless vehicles and autonomous robots.

“The model helps autonomous systems better know what they don’t know,” said first author Ramya Ramakrishnan from Computer Science and Artificial Intelligence Laboratory at MIT.

“Many times, when these systems are deployed, their trained simulations don’t match the real-world setting [and] they could make mistakes, such as getting into accidents.

“The idea is to use humans to bridge that gap between simulation and the real world, in a safe way, so we can reduce some of those errors,” explained Ramakrishnan.

The AI systems powering driverless cars are trained extensively in virtual simulations to prepare the vehicle for nearly every event on the road.

But sometimes the car makes an unexpected error in the real world because an event occurs that should, but doesn’t, alter the car’s behaviour.

The researchers validated their method using video games, with a simulated human correcting the learned path of an on-screen character.

The next step is to incorporate the model with traditional training and testing approaches for autonomous cars and robots with human feedback.

New Electric Car by Sony Leaves Car Makers Worried: Report

Why car makers should be afraid of Sony's electric car

One of the biggest surprises at this year’s CES 2020 came in the form of a new concept car unveiled by the entertainment and tech giant Sony – a move that must make traditional car makers worried, says a new report.

According to data-driven market research company Cascend, the car was built by Sony’s internal AI and robotics team (who makes their robotic dog, Aibo) with (significant) engineering support from Austria-based automotive contract manufacturer Magna Steyr.

“With increasing sensors, displays, controllers and infotainment, vehicles are becoming more-and-more like electronics products,” said the report.

Sony already makes display and infotainment systems which are becoming much more important parts of the car and controls.

Sony also makes high-res CMOS optical cameras and sensors, solid state lidar, radar and time-of-flight sensors — integrated into an advanced driver assistance system which Sony calls its ‘Safety Cocoon’,” the report added.

Called the Sony Vision-S, the concept car is an electric concept sedan.

It comes equipped with a phenomenal 33 different sensors both outside and inside the car, a widescreen display, 360 degree audio, and always-on connectivity, with some pieces coming from industry players like BlackBerry and Bosch.

Vision S is also powered by a “newly-designed EV platform” — engineered by automotive supplier Magna.

“Sony outsourced much of the “car stuff” from autoparts makers powered by an EV “platform” (supposedly engineered by auto supplier Magna) that Sony expects will be able to power other vehicles (like SUVs),” the report said.

Electric vehicles are a massive disruption in car-makers’ manufacturing processes. Their core technologies around combustion engines, drive trains, suspension and body design (over 100 years of development) aren’t particularly relevant.

“And because of this, new EV companies (which aren’t traditional car makers) are springing up everywhere,” said the report.

China understands they can leapfrog traditional car makers (of which they have basically none) to become a powerhouse in EV and are investing heavily. (IANS)
