Abstract: A vector-labeled database may improve a cache hit rate for read requests by performing a partial approximate nearest neighbor index search at a router to designate the cache that results of a read request are to be written to. The selected cache may be associated with a particular node of a layer of an approximate nearest neighbor index search. The router may direct all reads with search vectors close to the particular node to the associated cache.

Abstract: Selective frequency dissipation is implemented that enables cooling of energy gap protected qubits such that excited energy states resulting from heating or other undesired processes are returned to a lower excited energy state or a ground state manifold, thus reducing the probability of errors. Also, the selective frequency dissipation inhibits leakage from the energy gap protected qubits when in the ground state. Additionally or alternatively, Hamiltonian engineering by inducing parity rotations is implemented to decouple the wells of the energy gap protected qubit to further reduce errors when leakage does happen.

Abstract: A vector-labeled database, which stores data in association with multi-dimensional vectors, comprises a hot tier which is optimized for writes, a cold tier which is optimized for reads, and a medium tier which is optimized to balance reads and writes. Incoming transactions are executed at the hot tier, and moved to the medium and cold tier in batches. Reads for the vector-labeled database search all tiers, and merge the results of the searches of the individual tiers.

Abstract: Devices and techniques are generally described for machine translation. In various examples, first text in a first spoken language may be received. A first candidate translation of the first text in a second spoken language may be determined based at least in part on the first text from among a candidate pool of non-translated text associated with a first domain. Combined data representing the first text and the first candidate translation may be generated. A first machine learning model may generate second text by modifying at least one word of the first candidate translation. The second text representing a machine translation of the first text may be output.

Abstract: Techniques for filtering for harmful generative artificial intelligence (AI) results are described. An example of filtering includes receiving a request for an input phrase to be responded to by a generative AI model; comparing to the received input phrase to at least one known harmful input phrase to determine that the received input phrase is to be provided to the generative AI model; providing the received input phrase to the generative AI model; and generating a response by at least in part on an output of the generative AI model.

Abstract: A station is used to induct item(s) into an environment. The station includes a case module configured to receive the item(s), which may be packaged in a box, and sensor(s) configured to scan the box. A camera and lighting module of the station may read the item(s) as they are unpackaged from the box and transferred into one or more totes located on a tote module. The item(s) may be passed over the camera and lighting module and then placed into the tote. Sensor(s) are used to determine which of the one or more totes the item(s) are placed. As the tote(s) become full, the tote(s) may be inducted into the environment for storage, order fulfillment, etc. The station may be used to conveniently remove item(s) from their boxes and place the item(s) into the totes that allow automated storage systems to move the totes throughout the environment.

Abstract: Approaches presented herein relate to the management of secure secrets in a distributed environment. In particular, various embodiments provide for the management of unique digital identities across multiple regions, where each region can include its own certificate authority. While these certificate authorities may operate independently, they can be part of a multi-primary system where unique identities and keys are stored redundantly across environments. In the event of a failure of a certificate authority in one region, another certificate authority in another region can continue security and authentication management, without a need to issue new identities or change operation of any of the regions. Parties to secure communications, such as application containers, can each receive their own unique identity which can be shared across various regions to allow related tasks (e.g., certificate issuance or revocation) to be performed identically from any of those regions.

Abstract: Techniques for heat management in a serverless managed database service in a cloud provider network are described. The service receives a request to launch a database instance that can scale resource usage based on a computing resource demand of a database application. A set of candidate host computer systems to host the database instance is identified. A host resource usage metric of each host computer system in the set of candidate host computer systems is obtained. A host computer system from the set of candidate host computer systems is selected to host the database instance, the selection based at least in part on the host resource usage metric of the selected host computer system. The database instance is launched on the selected host computer system.

Abstract: Systems and methods are provided for an improved business intelligence platform that maintains and uses personalized data cache for processing natural language queries with personalized fuzzy matching in lieu of using predefined indexes of large amounts of data. The systems and methods provide for performing fuzzy matching using a natural language query and a personalized data cache storing a copy of data previously provided in response to interactions associated with a user profile, wherein the personalized data cache is separate from a data source storing the response data, and wherein the fuzzy matching does not use any fuzzy index of the data source generated prior to receiving the natural language query; obtaining, from results of the fuzzy matching, a set of query terms; obtaining the response data from the data source using the set of query terms; and generating a response to the natural language query using the response data.

Abstract: Techniques for securing DHCP communications between DHCP servers and client devices in a network to authenticate the devices before providing IP addresses. A client device may store one-time programmable (OTP) seed parameters, and use the OTP seed parameters to derive a unique private key. The private key is used to sign payloads of each DHCP packet sent to the DHCP server. The DHCP server is provided with a public key that verifies signatures made using the private key, and is also provided a list of unique identifiers for client devices that are permitted into the network. The DHCP server uses the public key to verify signatures on DHCP packets, and further verifies that the unique identifier in the DHCP packets is included in the list of expected unique identifiers. Firmware code measurements can be sent in the DHCP packets for the DHCP server to authenticate firmware of the client device.

Each container is configured to hold one or more items. The system also includes a robotic arm having an end effector configured to pick a target item from one of the plurality of containers. The end effector includes (i) first and second plates disposed parallel to each other and (ii) an extendable suction cup disposed between the first and second plates. The end effector is configured to extend the extendable suction cup to contact the target item, create a seal with the target item, after creating the seal, retract the extendable suction cup to remove the target item from the container, and after retracting the extendable suction cup, engage the target item between the first and second plates.

Abstract: Systems and methods are disclosed for implementation of a scalable and efficient scaling algorithm for clustering data objects within a data set, as well as implementation of the algorithm to control content generation and selection. A data set can be initially divided randomly into subsets. A base clustering algorithm, such as k-means clustering, can be applied in parallel to each subset to identify a set of local centroids representative of local clusters within each subset. The local centroids can be aggregated from across subsets and the base clustering algorithm can be applied to the aggregated local centroids to result in global clusters. Data objects associated with each global cluster (such as by being clustered within a local cluster corresponding to a global cluster) represent a global clustering of the data set. These global clusters can form the basis for additional iterations of local and global clustering, further refining global clustering.

Abstract: A system receives a request for content insertion in a web page for presentation at a device. The request includes contextual information about web traffic between the device and a web server, and the request excludes an identifier of a user of the device. The system associates the request with a cohort that represents a set of previous content insertion requests and characterized by a set of attribute values. The system determines a property of the cohort. The property indicates a count of previously presented content or a decision regarding blocking a future insertion of the content. The system determines that the content can be inserted in the web page. The system sends to the web server in response to the request, an indication to insert the content in the web page. The indication causes the content to be shown in the web page upon presentation at the device.

Abstract: Centralized data set management techniques are implemented for data sets for machine learning applications. New data sets may be created from a search of managed data set labels. Data objects of the managed data sets that are found in the search are then used to generate a new data set. The new data set is then made available for machine learning applications to use.

Abstract: Techniques for permission controls from a first provider for a second provider are described. In an example, a computer system stores first account data of a user with a first service provider. The first account data enables execution of a first online service of the first service provider to provide a second online service of a second service provider. The computer system receives second account data of the user with the second service provider. The computer system generates, based on a mapping between a first schema of the second account data and a second schema, third account data. The computer system generates, based on the first account data and the third account data, a report associated with controlling execution of the second online service. The computer system sends permission data to the second service provider indicating whether a permission exists to control the execution of the second online service.

Abstract: Methods and apparatus for conditional master election in a distributed database are described. A plurality of replicas of a database object are stored by a distributed database service. Some types of operations corresponding to client requests directed at the database object are to be coordinated by a master replica. Client access to the database object is enabled prior to election of a master replica. In response to a triggering condition, a particular replica is elected master. The master coordinates implementation of operations with one or more other replicas in response to client requests.

The system receives data associated with the packages in the MHE, and causes, at a first instance in time, the wedge to move from the retracted state to the extended state, and causes, at a second instance in time, the wedge to move from the extended state to the retracted state.

Abstract: Described are apparatuses, assemblies, and processes to create a carbon fiber part with a smooth convex surface using an interior mold. An uncured part may be formed by wrapping fiber and resin around a mandrel (interior mold). One or more caul plate and optional shims may be placed over the uncured part in alignment with features that correspond between the caul plate(s) and the mandrel. The assembly may be enclosed in a vacuum bag and consolidated. The assembly may be placed on a jig base. A compression member may be coupled to the jig base to contain the assembly therebetween. The compression member may exert a force onto the caul plate to compress the uncured part against the mandrel during a curing process, thereby creating a smooth surface finish of the resulting cured part that is free from substantial undesirable warping or wrinkles about the surface.

Abstract: Techniques for generating a multi-modal, context aware embedded representation of an entity and contextual data associated with the entity are described. The system may receive a natural language entity for which an embedded representation is to be generated. The system uses the natural language entity to determine/generate various context data associated with the entity (e.g., slot type, usage example, phonemes, audio data, image/video data, etc.). The system may tokenize and encode the natural language entity and the context data. Thereafter, the encoded entity and the context data may be inputted to a language model, which generates a single embedded representation corresponding to the entity and the context data. Thereafter, the embedded representation may be used by a system component for performing processing with respect to a user input.
