 Around ten years ago, a little girl named Lisa went for a walk in the forest right there in outskirts of Moscow. They never came back. Authorities were all preoccupied with the celebration of the city day and terrified parents who went to social networks in the cry for help. And 500 people joined them and went to the forest in search for Lisa. And on day nine, the tragedy happened. They found Lisa's body. Four-year-old girl died of hypothermia. And in memory of Lisa, those 500 people created a volunteer movement with only one purpose – not to allow this tragedy to happen again. In Russia, most cities are surrounded by heavy forests and we have literally hundreds of thousands of people every sunny weekend going out in the forest. And this relates to a huge number of lost people. 120,000 people are getting lost in Russia every year and Lisa Alert is on the forefront of search and rescue operations. Our story with Lisa Alert began nine years ago. It's all started with basic SMS portal, which we developed to manage 50,000 Lisa Alert volunteers. And now we are going further. With artificial intelligence and 5G network, we are bringing Lisa Alert's operations to the new level. We knew that Lisa Alert had been using drones with limited results. The challenge was to make this technology more effective. Previously, 2,500 images were being captured by drones during 35 minutes of flight. These had to be manually uploaded. After that, 30 volunteers would look for them spending up to six hours. Our engineers developed an artificial intelligence model and neural network that can rapidly identify people on images by sending them in a real-time to our data centers over Beeline's mobile network, reducing the analysis time to two minutes. These results are then sent to Lisa Alert, so they can focus on the correct coordinates. Our biggest challenge is the search path. That's the most time consuming. With this technology with drones, the search path can be reduced dramatically so we can go directly to evacuation path. We are always looking for the future technologists and see how they can help Lisa Alert. Heatmaps will enable drones to work at night. Big Data will analyze circle of friends who missing person might have been in communication with and all of us will make search faster and faster. Lisa Alert is much more than just search and trace operations. Different people from different background come together to do something good. In the first nine months of 2019, over 15,000 people return home alive. But this very moment, more than 3,000 people are still missing. Together with Lisa Alert, we are committed to help rescue them because we strongly believe that those who are lost shall be found.
