    Abstract: An input device determines presence of an actual user, instead of an artifact, by using multi-wavelength reflectance spectroscopy. Light sources are operated to illuminate an object with different colors of light at different times. A detector determines, at those different times, intensity data indicative of intensity light of these different colors as reflected from the object. The intensity data is processed to determine whether the object is part of a user or is an artifact. For example, if the object is deemed to be a user, biometric input may be acquired. The biometric input may then be processed to identify the user. The input device may be used at various locations, such as at an entry portal, point of sale, and so forth.

    Abstract: Systems and methods are disclosed to perform gradient exchange among processing nodes configured as a hyper-rectangle network of N-dimensions. Each processing node can operate as a collective parameter server node capable to perform collective compute operations. For each dimension in a sequence of dimensions, all processing nodes on a same edge can perform a scatter-reduce operation using respective collective parameter serving engines. The amount of data reduced in each dimension is an inverse of a number of processing nodes in that dimension. After the scatter-reduce operation is performed for all the dimensions, all processing nodes on the same edge can perform an all-gather operation for each dimension in a reverse sequence of dimensions.

    Abstract: Techniques are described that enable users to configure the mirroring of network traffic sent to or received by computing resources associated with a virtual network of computing resources at a service provider network. The mirrored network traffic can be used for many different purposes including, for example, network traffic content inspection, forensic and threat analysis, network troubleshooting, data loss prevention, and the like. Users can configure such network traffic mirroring without the need to manually install and manage network capture agents or other such processes on each computing resource for which network traffic mirroring is desired. Users can cause mirrored network traffic to be stored at a storage service in the form of packet capture (or “pcap”) files, which can be used by any number of available out-of-band security and monitoring appliances including other user-specific monitoring tools and/or other services of the service provider network.

    Abstract: Systems and methods are disclosed for containers having mechanical secured door indicators. In one embodiment, an example container may include a first container wall, a second container wall, a third container wall, and a fourth container wall configured to move from an open position to a closed positon. The fourth container wall may include a first portion coupled to the second container wall, and a second portion coupled to the third container wall, where the first portion and the second portion are coplanar when the fourth container wall is in the closed position. The foldable container may include a bottom container platform having a machine-readable code, and a pivotable arm configured to cover the machine-readable code when the fourth container wall is in the closed position, and to uncover the machine-readable code when the fourth container wall is not in the closed position.

    Abstract: Techniques for caching in a machine learning model (ML) hosting service are described. ML model usage data is aggregated from host usage data provided from each host of a first set of hosts, the ML model usage data including, for a particular ML model, a number of inference requests to the particular ML model. A priority order of hosts in a second set of hosts to service an inference request for the particular ML model is calculated. Based on the ML model usage data and the priority order, a set of ML models to load to a particular host in the second set of hosts is determined. The particular host is caused to load the set of ML models. A router is updated to direct ML model inference requests amongst the second set of hosts.

    Abstract: A computing system may determine audio data representing a message that is to be provided to a first user, wherein the first user is associated with at least a first device and a second device. First data corresponding to an audio characteristic of a first physical environment in which the first device is located and second data corresponding to the audio characteristic of a second physical environment in which the second device is located may be determined, wherein the second physical environment is different than the first physical environment and the second data is different than the first data. The computing system may determine, based at least in part on the first data and the second data, that the second physical environment is better suited for outputting audio corresponding to the message than the first physical environment, and may send the audio data to the second device via a network to cause the second device to output the audio based at least in part on the second physical environment being better suited for outputting the audio than the first physical environment.
