New delhi sources stated that two digital applications (apps) developed by Indian under-graduate students for women's safety and to check air pollution in Delhi on smart phones won Marconi Society annual awards for the good of humanity. An official said "The Android application named 'Rakshak' detects speech patterns through an audio microphone of any user's smart phone".
Furthermore the app generates the alert after analyzing emotion and distress speech patterns. It was named after Nobel laureate (Physics) Guglielmo Marconi (1874-1937), who invented the radio in 1908, the Society was set up in 1975 by his daughter Gioia Marconi Baraga through an endowment, which annually gives awards for outstanding contribution in science and the principle of creativity in the service of humanity.
As per the statement "The new app builds on the work done by last year's Celestini prize winners, which showed that a machine learning model can be built to estimate air quality from an image by extracting image features such as transmission index or haziness and combining them with meteorological data and historical air quality data". Moreover the VisionAir team also enables other developers to create new machine learning models by open-sourcing smart phone images from several locations in delhi, from different phones with ground truth air quality data from Central Pollution Control Board monitors and Airveda sensors.
