Flexible reference picture management for video encoding and decoding
Innovations in flexible reference picture management are described. For example, a video encoder and video decoder use a global reference picture set (“GRPS”) of reference pictures that remain in memory, and hence are available for use in video encoding/decoding, longer than conventional reference pictures. In particular, reference pictures of the GRPS remain available across random access boundaries. Or, as another example, a video encoder and video decoder clip a reference picture so that useful regions of the reference picture are retained in memory, while unhelpful or redundant regions of the reference picture are discarded. Reference picture clipping can reduce the amount of memory needed to store reference pictures or improve the utilization of available memory by providing better options for motion compensation. Or, as still another example, a video encoder and video decoder filter a reference picture to remove random noise (e.g., capture noise due to camera imperfections during capture). |

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for hotword detection on multiple devices are disclosed. In one aspect, a method includes the actions of receiving audio data that corresponds to an utterance. The actions further include determining that the utterance likely includes a particular, predefined hotword. The actions further include transmitting (i) data indicating that the computing device likely received the particular, predefined hotword, (ii) data identifying the computing device, and (iii) data identifying a group of nearby computing devices that includes the computing device. The actions further include receiving an instruction to commence speech recognition processing on the audio data. The actions further include in response to receiving the instruction to commence speech recognition processing on the audio data, processing at least a portion of the audio data using an automated speech recognizer on the computing device. |

Inferring sentiment to manage crowded spaces by using unstructured data
Facilities of a shared environment are automatically optimized by inferring sentiment from unstructured conversational data towards various environmental entities such as heat, light, service levels, etc. Conversational audio streams from different areas are analyzed to identify an entity and associated sentiment, and a heatmap is created representing the sentiment across the different areas. The conversational audio streams are captured by directional microphones and are assigned metadata such as a location tag indicating a position of a microphone within the shared environment. Heatmap creation can be supplemented by other sensory data. A cognitive system is used to generate actions for control of the facilities based on the heatmap. A suggested action may still be subject to operational policies for the facility. In some scenarios a first suggested facility action compensates for an effect of a second suggested facility action. |

Method for a virtual assistant, data processing system hosting a virtual assistant for a user and agent device for enabling a user to interact with a virtual assistant
A method for a virtual assistant is provided. The method includes controlling, in a first operation mode, at least one sensor to sense a physical quantity. Further, the method includes receiving, in the first operation mode, sensor data indicative of the physical quantity from the at least one sensor. Additionally, the method includes processing, in the first operation mode, the sensor data to detect whether the sensor data exhibit a predetermined characteristic. If the predetermined characteristic is detected in the sensor data, the method includes setting the operation mode of the virtual assistant to a second operation mode assigned to the predetermined characteristic. |

Generation of matched corpus for language model training
A computer-implemented method for generating a text is disclosed. The method includes obtaining a first text collection matched with a target domain and a second text collection including a plurality of samples, each of which describes rewriting between a first text and a second text that has a style different from the first text. The method also includes training a text generation model with the first text collection and the second text collection, in which the text generation model has, in a vocabulary, one or more operation tokens indicating rewriting. The method further includes outputting a plurality of texts obtained from the text generation model. |

Personalizing a DNN-based text-to-speech system using small target speech corpus
A personalized text-to-speech system configured to perform speaker adaption is disclosed. The TTS system includes an acoustic model comprising a base neural network and a differential neural network. The base neural network is configured to generate acoustic parameters corresponding to a base speaker or voice actor, while the differential neural network is configured to generate acoustic parameters corresponding to differences between acoustic parameters of the base speaker and a particular target speaker. The output of the acoustic model is then a weighted linear combination of the output from the base neural network and differential neural network. The base neural network and differential neural network share a first input layer and first plurality of hidden layers. Thereafter, the base neural network further comprises a second plurality of hidden layers and output layer. In parallel, the differential neural network further comprises a third plurality of hidden layers and separate output layer. |

System and method for 3D display of dynamic objects on synthetic vision system in cockpit display system
A method for displaying objects in an aerial vehicle is disclosed. The method includes: determining if sensed objects or calculated virtual objects around the travel path of the aerial vehicle are within a field of view of a three-dimensional view in front of the aerial vehicle displayed on a display screen in the aerial vehicle; selecting, for each graphical object representing an object within the field of view of the three-dimensional view, a graphical object display size for the object, wherein the display size of an object is determined based on a non-linear projection per distance between the object and the view point that is scaled based on a continuous, non-linear scaling function, which causes the object to be displayed smaller at certain distances and larger at other distances than it would if linear scaling alone were applied; causing the display of the one or more graphical objects with the selected display size. |

System and method for prioritizing AR information based on persistence of real-life objects in the user's view
Systems and methods described herein in accordance with some embodiments may display augmented reality (AR) information related to an object based on a predicted persistence of the object within view of the user. In some embodiments, display of AR information is prioritized based upon a prediction of how soon an object will disappear from view, perhaps if the predicted disappearance will occur sooner than some threshold time. Systems and methods described herein in accordance with some embodiments extend to mixed reality (MR) systems, and provide for displaying an image of an object that has become obstructed or has disappeared from view and/or for displaying AR information related to an object that has become obstructed or has disappeared from view. |
