Abstract: A method includes receiving a training example that includes audio data representing a spoken utterance and a ground truth transcription. For each word in the spoken utterance, the method also includes inserting a placeholder symbol before the respective word identifying a respective ground truth alignment for a beginning and an end of the respective word, determining a beginning word piece and an ending word piece, and generating a first constrained alignment for the beginning word piece and a second constrained alignment for the ending word piece. The first constrained alignment is aligned with the ground truth alignment for the beginning of the respective word and the second constrained alignment is aligned with the ground truth alignment for the ending of the respective word. The method also includes constraining an attention head of a second pass decoder by applying the first and second constrained alignments.

The first device may include a set of contacts and a second device may include a second set of contacts. The second set of contacts may be adapted to electronically engage with the first set of contacts of the first device to form at least a power and ground lines connection. Circuitry within the first device and the second device may include circuitry for providing data over the power line connection between the first device and the second device. The circuitry may comprise a power line, a ground line, a transmitter line carrying data signals, a capacitor coupling the transmitter line to the power line at a connection point, and a receiver comprising two field effect transistors.

Abstract: This document describes techniques and apparatuses directed at reducing intermodulation distortion effects in hearable devices. In aspects, an apparatus includes a first speaker and a second speaker disposed within a housing having an acoustic cavity adjacent to an aperture. The first speaker includes a first diaphragm facing the acoustic cavity and coupled to the housing by a forward roll surround. The second speaker includes a second diaphragm facing the acoustic cavity and coupled to the housing by a reverse roll surround. Intermodulation distortion effects that arise at the first diaphragm having the forward roll surround and the second diaphragm having the reverse roll surround are substantially offset by each other at the aperture.

Abstract: This document describes systems and techniques for a low-latency bridge to support out-of-order execution. The described systems and techniques can facilitate out-of-order execution by a memory controller of in-order transaction requests. When it receives transaction responses associated with in-order transaction requests, the bridge can send a first transaction response without storing it in a reorder buffer. Similarly, the bridge can determine whether a next transaction response is available to send to the respective client. The bridge introduces latency to a larger system (e.g., an SoC) only when a secondary response (e.g., not first) of in-order transaction responses is received first. In this way, the memory controller can process transaction requests from one or more clients with minimal latency introduced by the bridge and a smaller reorder buffer.

Abstract: A display panel includes an array of pixels extending in a plane and arranged in rows, wherein a first plurality of the rows extend to an edge of the pixel array and one or more rows at a corner of the pixel array are recessed from the edge. The display panel includes driver circuits each connected to a corresponding row of the pixel array and occupying an area in the plane, the area having a long dimension and an orthogonal short dimension. A first set of driver circuits are connected to corresponding rows of the first plurality of rows and a second set of driver circuits are connected to corresponding rows at the corner of the pixel array. The long dimension of each of the drivers of the first set of drivers is greater than the long dimension of each of the drivers of the second set of drivers.

Abstract: Systems and methods for compression of data that exhibits mixed compressibility, such as floating-point data, are provided. As one example, aspects of the present disclosure can be used to compress floating-point data that represents the values of parameters of a machine-learned model. Therefore, aspects of the present disclosure can be used to compress machine-learned models (e.g., for reducing storage requirements associated with the model, reducing the bandwidth expended to transmit the model, etc.).

Abstract: The disclosure is directed towards systems and methods for improving security in a computer network. The system can include a planner and a plurality of controllers. The controllers can be deployed within each zone of the production network. Each controller can be configured to assume the role of an attacker or a target for malicious network traffic. Simulations of malicious behavior can be performed by the controllers within the production network, and can therefore account for the complexities of the production network, such as stateful connections through switches, routers, and other intermediary devices. In some implementations, the planner can analyze data received from the controllers to provide a holistic analysis of the overall security posture of the production network.

Abstract: Some implementations relate to an automated assistant that can provide assistant suggestions based on content that the user has requested for the automated assistant to render at a computing device. In some instances, an assistant suggestion can correspond to a portion of the content that is not being rendered at the computing device but that is part of the content that the user is accessing. In other instances, an assistant suggestion can be based on data that can indicate how one or more users may have interacted with their automated assistant when viewing the content. Therefore, an assistant suggestion can correspond to an assistant operation that may have been initialized by another user who had previously viewed the content. In some implementations, an arrangement of the assistant suggestions can be modified according to which part of the content a user is viewing and/or user distance.

Abstract: Methods, systems, and media for navigating a user interface with a toolbar are provided.

Abstract: The present disclosure is generally related to a data processing system to determine operational statuses of agents interfacing with digital assistant applications. The data processing system can access a log database. The log database can maintain response metrics for an agent service. Each response metric can correspond to a response by the agent service to a request generated by a digital assistant application responsive to an input audio signal. The data processing system can transmit a ping request to the agent service and can wait for a second response from the agent service. The data processing system can determine an operational status of the agent service based on the response metrics and on a time elapsed since the transmission of the ping request. The data processing system can cause the digital assistant application to perform an action based on the operational status.

Abstract: Provided are systems and methods for synthesizing novel views of complex scenes (e.g., outdoor scenes). In some implementations, the systems and methods can include or use machine-learned models that are capable of learning from unstructured and/or unconstrained collections of imagery such as, for example, “in the wild” photographs. In particular, example implementations of the present disclosure can learn a volumetric scene density and radiance represented by a machine-learned model such as one or more multilayer perceptrons (MLPs).

Abstract: Embodiments are provided for managing the operation of sensors in an electronic device. According to certain aspects, the electronic device may detect a change in motion from a set of lower-sensitivity sensor data generated by a sensor(s) operating in a lower-sensitivity mode. When the change in motion is detected and during a timeout window, the sensor(s) may generate an additional set of lower-sensitivity sensor data and a set of higher-sensitivity sensor data. The electronic device may initially confirm the change in motion based on analyzing the set of higher-sensitivity sensor data. Further, the electronic device may determine that the additional set of lower-sensitivity does not indicate an additional change in motion, and may deem the confirmation of the change in motion as a false positive.
