San Francisco, May 3: After making deep investments in Artificial Intelligence (AI) technology, Facebook has announced the next version of its open-source AI framework for developers.

Called "PyTorch 1.0", the framework provides everyone in the AI research community with a fast, seamless path for building a broad range of AI projects.

"The technology in PyTorch 1.0 is already being used at scale, including performing nearly 6 billion text translations per day for the 48 most commonly used languages on Facebook," the company announced during its F8 developer conference in San Jose on Wednesday.

The AI research and engineering teams at Facebook have successfully trained an image recognition system on a dataset of 3.5 billion publicly available photos, using the hashtags on those photos in place of human annotations.

"This new technique will allow our researchers to scale their work much more quickly, and they've already used it to score a record-high 85.4 per cent accuracy on the widely used 'ImageNet' benchmark," Facebook said.

The "PyTorch 1.0" toolkit will be available in beta within the next few months, making Facebook's state-of-the-art AI research tools available to everyone.

"With it, developers can take advantage of computer vision advances like 'DensePose', which can put a full polygonal mesh overlay on people as they move through a scene- something that will help make AR camera applications more compelling," the company said.

Mumbai (PTI): Aviation watchdog DGCA on Friday eased the flight duty norms by allowing substitution of leaves with a weekly rest period amid massive operational disruptions at IndiGo, according to sources.

As per the revised Flight Duty Time Limitations (FDTL) norms, "no leave shall be substituted for weekly rest", which means that weekly rest period and leaves are to be treated separately. The clause was part of efforts to address fatigue issues among the pilots.

Citing IndiGo flight disruptions, sources told PTI that the Directorate General of Civil Aviation (DGCA) has decided to withdraw the provision 'no leave shall be substituted for weekly rest' from the FDTL norms.

"In view of the ongoing operational disruptions and representations received from various airlines regarding the need to ensure continuity and stability of operations, it has been considered necessary to review the said provision," DGCA said in a communication dated December 5.

The gaps in planning ahead of the implementation of the revised FDTL, the second phase of which came into force from November 1, have resulted in crew shortage at IndiGo and is one of the key reasons for the current disruptions.
