Abstract: The system trains a machine learning model using a loss function, with a part that penalizes overall signal loss, and a second part of the loss function that penalizes texture loss. The system computes a first neural feature of a first media frame stored by a media server using the trained machine learning model. The system causes a client device to receive a second media frame as a part of a media stream from the media server where the second frame is a modified version of the first media frame. The system causes the client to compute a second neural feature of the second media frame using the trained machine learning model, and compute a QoE metric based on the first neural feature and the second neural feature. The system receives the QoE metric, and uses it to modify at least one parameter of the media stream.

Abstract: A soil layer detection drilling device includes a drilling cylinder, and a soil-sampling assembly is provided inside the drilling cylinder. When the soil is drilled, equipment is in a vertical state, a controller is turned on to control a rotary motor to rotate, and the drilling cylinder is driven to drill the soil with the cooperation of drive wheels and a drive belt. Four slide blocks are evenly distributed around an outer circumference of a sliding disk and are matingly connected with slide grooves provided on an inner wall of the drilling cylinder, so when the drilling cylinder rotates, the soil-sampling assembly also rotates. A conical head first in contact with the ground starts to drill the ground, then the drilling cylinder gradually drills into a soil layer, and the drilling cylinder is idled as the drilling cylinder arrives at a certain depth, to clear soil on auger blades.

Abstract: Systems and methods are provided herein for engaging navigation modes based on traffic events. For example, the disclosed system receives a request for navigating a user device from a start location to a final destination. The user device optionally indicates that turn-by-turn navigational directions are to be provided from an intermediate location to the final destination. The system determines all possible routes the user device can take from the start location to the intermediate location and, in some embodiments, from the intermediate location to the final destination. Once engaged, the system monitors the user device's progress from the start location to the intermediate location without displaying turn-by-turn navigation. During which time, the system notifies the user device of any traffic events that may impact the journey. When prompted, the system provides turn-by-turn navigational directions to bypass the traffic event.
