Abstract: Techniques for analyzing access control policies across multiple provider networks. These techniques compile various policies into a unified policy language broad enough to include diverse policy features, yet specific enough for automated analysis. An automated differential testing method is employed to confirm the accuracy of this compilation by generating access requests, ensuring both original and translated policies consistently grant or deny access. Moreover, an abstraction technique is used to simplify and correlate the complex details of different policies, enabling easier user inquiries about them. For instance, users can determine if an account has write access in one network but not in another. This abstraction sometimes involves replacing actions in original policies, ensuring their compatibility in the target policy language.

Abstract: Techniques for using a language model (e.g., a large language model (LLM)) to generate a natural language response to a user input and prosody information (e.g., voice characteristics associated with a synthetic voice to output the natural language response to the user) are described. The prosody information may correspond to a natural language (e.g., text or tokenized) description, a spectrogram, and/or a latent representation of the voice characteristic(s) associated with the natural language response. In some embodiments, the natural language response and the prosody information may be generated by different portions of layers of the language model. In such embodiments, the output of the layer(s) of the language model configured to generate the natural language response may be provided to the layer(s) of the language model configured to generate the prosody information and the output may be used to generate the prosody information, and vice versa.

Abstract: Methods, systems, and computer-readable media for interactive command generation for natural language input are disclosed. A natural language dialog system receives a natural language input for a dialog with a user. The system determines a state representation of the dialog based at least in part on the natural language input. The state representation indicates an operation offered by a service. The system generates a natural language output based at least in part on the natural language input. The natural language output solicits an additional natural language input for the dialog. The system determines an updated state representation of the dialog based at least in part on the additional natural language input and the state representation. The updated state representation indicates parameter value(s) for the operation. Based at least in part on the updated state representation, the system generates a command invoking the operation with the parameter value(s).

Abstract: Connectivity between a radio-based application pipeline processing server and a control plane of a provider network is verified. Based on requests received at the control plane, a first isolated request handler, a second isolated request handler and an offloading manager are launched at the server. The offloading manager causes a first network function for which a request is received from the first request handler to be executed at a first network function accelerator of the server, and a second network function for which a request is received from the second request handler to be executed at a second network function accelerator of the server.

Abstract: An improved search system can address sparse behavioral signals. Machine learning is used to determine queries with historical data that are similar to an input query, which have limited behavioral signals. Co-acquisitions of items for query pairs are used to generate a similarity value for the pairs, which are used as labels during training of machine learning models. Multiple machine learning models are used during inference such that a subset of similar queries is determined with a less computationally expensive model and a more computationally expensive model is used to re-rank the subset of queries. Accordingly, for input queries with limited behavioral data, the search system identifies similar queries with behavioral data and their corresponding search results can be presented to a user.

Abstract: A system is provided for a self-learning policy engine that can be used by various spoken language understanding (SLU) processing components. The system also provides for sharing contextual information from processing performed by an upstream SLU component to a downstream SLU component to facilitate decision making by the downstream SLU component. The system also provides for a SLU component to select from a variety of actions to take. A SLU component may implement an instance of the self-learning policy that is specifically configured for the particular SLU component.

Abstract: Described implementations monitor potential voltage at a location to determine device usage at the location. The implementations utilize a plug-in energy sensor that is plugged directly into any electrical outlet at the location and measures deviation in voltage at the location. Once plugged into an electrical outlet, the plug-in energy sensor monitors one or more of the lead line and ground, the neutral line and ground, and/or the ground line with respect to a reference for changes in potential voltage at the location. Different devices and different device states of those devices generate different signatures of voltage as they operate, thereby making the signatures unique, or almost unique, to different device types, different devices, and/or different device states. By monitoring for signatures in the voltage, operation of devices in different device states at the location can be determined, along with start times and stop times of those states associated with the various devices.

Abstract: Techniques for implementing instance local boots in a cloud provider network via auxiliary domains are described. An auxiliary compute instance is launched and attached to a local storage device of the computing device. The auxiliary compute instance can pre-warm a boot volume by fetching its data from a remote system and storing the boot volume to the local storage device. The auxiliary compute instance is terminated, and a user compute device is launched into the same slot and connected to the local storage device. The user compute device utilizes the pre-warmed boot volume for launch.

Abstract: In networks, some communication links may be provided as part of a network overlay. Technologies are disclosed for monitoring/analyzing targeted networks (e.g., network overlays) using probe packets sent from outside of the targeted networks/overlays. The probe packets are configured to include a stack of headers, including indications of UDP source ports, which are respectively examined in order at network devices in the targeted network to determine a routing scheme to utilize to route the packet.
