Abstract: Coordinating processing of audio queries is provided. A system receives a query. The system provides the query to a first digital assistant component and a second digital assistant component for processing. The system receives a first response to the query from the first digital assistant component, and a second response to the query from the second digital assistant component. The first digital assistant component can be authorized to access a database the second digital assistant component is prohibited from accessing. The system determines, based on a ranking decision function, to select the second response to the query from the second digital assistant component. The system provides, responsive to the selection, the second response from the second digital assistant to a computing device.

Abstract: This application relates to apparatus and methods for training machine learning models. In some examples, a pool of worker pods are generated that can execute tasks to train a machine learning model. The pool of work pods are assigned tasks by a master that communicates with the worker pods using a work queue. Each worker pod can provide output using a results queue. The embodiments may operate with less reliable memory, such as object stores, which may be less costly than other types of storage mechanisms. To operate in less reliable environments, each worker pod can include a checkpoint mechanism that can recover from interruptions, such as interruptions due to node failure or preemption. For example, the checkpoint mechanism may allow a worker pod to continue processing a task, when the task is interrupted, from a last checkpoint. Processing results are provided to a results queue when a task completes.

Abstract: Systems and methods for assessing vehicle operation are provided. According to certain aspects, an electronic device may receive and analyze image data depicting an individual located within a vehicle. The electronic device may also access and compile certain data related to an environment of the vehicle, and specifically to the vehicle's position relative to the sun. According to embodiments, the electronic device may determine, based on the accessed data, whether the vehicle is traveling into a direction of the sun, and may generate and record an indication of the same.

Abstract: A system, method, and apparatus are provided for establishing a secure, split-terminated, communication connection between a client and a server (or two other communicants), without exposing to possible compromise one or more private keys used at an intermediate device to establish the communication connection. The private key(s) is or are stored on a key server that is separate from the intermediate device and from any other devices whose private keys are also stored on the key server. During the handshaking to establish the communication connection, one or more handshaking messages (or components of the messages) are submitted to the key server, by the intermediate device, for encryption or decryption with the corresponding key(s). The resulting encrypted or decrypted information is returned to the intermediate device for further action (e.g., to be forwarded or processed).
