Listening for illegal logging chainsaws using TensorFlow

Listening for illegal logging chainsaws using TensorFlow

Our team has built the world’s first scalable, real-time detection and alert system for logging and environmental conservation in the rainforest. Building hardware that will survive in the rainforest is challenging, but we’re using what’s already there: the trees. We’ve hidden modified smartphones powered with solar panels—called “Guardian” devices—in trees in threatened areas, and continuously monitor the sounds of the forest, sending all audio up to our cloud-based servers over the standard, local cell-phone network.

Could We Actually Nuke an Asteroid to Save Earth?

Could We Actually Nuke an Asteroid to Save Earth?

Two recent papers anticipate how nukes could be employed to either deflect an asteroid on a collision course with Earth, or blow it into smaller, less hazardous chunks. One, published in Acta Astronautica, proposes a vehicle called the Hypervelocity Asteroid Mitigation Mission for Emergency Response (HAMMER), which could be deployed to nudge asteroids away from Earth, or in a worst case scenario, as a delivery mechanism for a nuclear device.

Using Machine Learning to Improve Streaming Quality at Netflix

Network quality is difficult to characterize and predict. While the average bandwidth and round trip time supported by a network are well-known indicators of network quality, other characteristics such as stability and predictability make a big difference when it comes to video streaming. A richer characterization of network quality would prove useful for analyzing networks (for targeting/analyzing product improvements), determining initial video quality and/or adapting video quality throughout playback (more on that below).
