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.

Abstract: A neural text-to-speech system may be configured to emphasize words. Applying emphasis where appropriate enables the TTS system to better reproduce prosodic characteristics of human speech. Emphasis may make the resulting synthesized speech more understandable and engaging than synthesized speech lacking emphasis. Emphasis may be manually annotated to, and/or predicted from, a source text (e.g., a book). In some implementations, the system may use a generative model such as a variational autoencoder to generate word acoustic embeddings indicating how emphasis is to be reflected in the synthesized speech. A phoneme encoder of the TTS system may process phonemes to generate phoneme embeddings. A decoder may process the word acoustic embeddings and the phoneme embeddings to generate spectrogram data representing the synthesized speech.

Abstract: A feature deployment service of a provider network may deploy feature processing units (FPUs) to implement data processing features at both a provider network and edge devices. The use of FPUs may allow a client to use new features at the edge, without delays due to compliance/testing or software upgrades. An FPU includes a model and compute logic that are used to implement a data processing feature. A feature processing service deploys the FPU to an FPU engine at the provider network and also deploys the FPU to edge devices of the client's network that each include an edge FPU engine. The FPU engine at the provider network and the edge FPU engine at each edge device conform to a common specification/API, allowing deployment and use of the same FPU/data processing features at both the cloud and the edge.

Abstract: An agent running on an IoT device of a client's network may receive a default password from a provider network and use the received default password to determine whether the password assigned to the IoT device has been changed from the default password to a different one. The agent may retrieve a salt string, a hashing algorithm, and a hashed string from a password database of the IoT device, combine the salt string with the received default password to generate a salted default password, and apply the hashing algorithm to the salted default password to generate a new hashed string. The agent may then compare the new hashed string to the hashed string retrieved from the password database. If they match, then the agent sends an indication to the provider network that the default password is still assigned to the IoT device.

Abstract: Managed lifecycle roles are disclosed. Managed lifecycle roles may be used for secure credential vending or otherwise. For instance, an entity (e.g., administrator or other entity) requests, via an interface of a role manager, creation of a role associated with a lifecycle definition (e.g., an expression of an enforceable expiration of the role or similar characteristic). The role manager stores the role and role lifecycle definition to a data store. Another entity requests to use the role to perform some operation with respect to a resource. A credential service validates the request against a lifecycle definition for the role (and against an access control list, in some examples) and responds to valid requests with credentials useable to perform the operation with respect to the resource. The other entity uses the credentials to perform the operation with respect to the resource. A sweep process manages attributes of the roles.

Abstract: Anomalous interactions with a website or other system may be detected based on the types of characteristics associated with previous anomalous interactions, independent of the values associated with those characteristics. Historical data is used to determine characteristics of interactions, each characteristic having a type and a value. For historical interactions in which a set of characteristic values are associated with a potentially anomalous interaction, the characteristic types are analyzed in subsequent interactions. If values for those characteristic types occur at a frequency greater than a threshold frequency for a set of subsequent interactions, this may indicate that the interactions are anomalous. Use of the characteristic types for this purpose, rather than historical characteristic values, enables anomalous interactions to be detected independent of the characteristic values associated with the interactions.

Abstract: Methods, systems, and computer-readable media for unified search and navigation for cloud-based services are disclosed. A unified search system receives textual input entered using a search interface. The search interface is displayed in a user interface concurrently with a management console for a cloud provider network. Based (at least in part) on the textual input, the system performs a search using one or more indexes usable to determine service names and descriptive information for the services. The system generates search results comprising a portion of the service names and a portion of the descriptive information. The search results are displayed using a search results overlay that is displayed concurrently with at least a portion of the management console. The system receives additional input entered using the overlay and comprising a selection of a particular search result. Responsive to the selection, additional information associated with the particular search result is displayed.
