Titagarh (West Bengal), May 9, 2017: India is preparing a law for safeguarding its interest in Antarctica, an official of the Ministry of Earth Sciences (MoES) said here on Tuesday.
“India doesn’t have laws for Antarctica. We are preparing it and it is in circulation in the , law ministry,” MoES secretary Madhavan Nair Rajeevan told the media.
“The law entails regulating our activities. When we go there if we do a mistake, what will happen, what to do. It is about safeguarding our own interests,” he said.

Rajeevan said India is also poised to expand its research activities in the coldest continent.
Maitri, which is India’s second research station in Antarctica as part of the Indian Antarctic Programme, will be replaced by a new one in the next few years.
“The Maitri station will be replaced by a new station in the next three-to-four years. Scientific activities will be expanded. We are also planning to buy a ship which can go to Antarctica,” Rajeevan added. (IANS)
Just as most smartphone cameras now allow users to focus on a single object among many, it may soon be possible to pick out individual voices in a crowd by suppressing all other sounds, thanks to a new Artificial Intelligence (AI) system developed by Google researchers.
This is an important development as computers as not as good as humans at focusing their attention on a particular person in a noisy environment. Known as the cocktail party effect, the capability to mentally “mute” all other voices and sounds comes natural to us humans.
However, automatic speech separation — separating an audio signal into its individual speech sources — remains a significant challenge for computers, Inbar Mosseri and Oran Lang, software engineers at Google Research, wrote in a blog post this week. In a new paper, the researchers presented a deep learning audio-visual model for isolating a single speech signal from a mixture of sounds such as other voices and background noise.
“In this work, we are able to computationally produce videos in which speech of specific people is enhanced while all other sounds are suppressed,” Mosseri and Lang said. The method works on ordinary videos with a single audio track, and all that is required from the user is to select the face of the person in the video they want to hear, or to have such a person be selected algorithmically based on context.
The researchers believe this capability can have a wide range of applications, from speech enhancement and recognition in videos, through video conferencing, to improved hearing aids, especially in situations where there are multiple people speaking. “A unique aspect of our technique is in combining both the auditory and visual signals of an input video to separate the speech,” the researchers said.
“Intuitively, movements of a person’s mouth, for example, should correlate with the sounds produced as that person is speaking, which in turn can help identify which parts of the audio correspond to that person,” they explained.
The visual signal not only improves the speech separation quality significantly in cases of mixed speech, but, importantly, it also associates the separated, clean speech tracks with the visible speakers in the video, the researchers said. IANS
