Abstract: In the implementation of techniques for injecting faults by instrumentation code, a system identifies software and one or more fault configuration settings corresponding to faults for fault injection. Based on the fault configuration settings, the system then generates a modified version of the software code by generating instrumentation code via an agent and including the instrumentation code in the software code. The instrumentation code, when executed, is configured to simulate the faults having the fault configuration settings. Upon execution of the modified version of the software code including the instrumentation code by the system, the system simulates the faults as a fault injection. Based on the results of the fault injection, the system generates an outcome of the fault injection for display.

Abstract: Virtual environment arrangement and configuration techniques are described. In one example, virtualization techniques are employed to generate a virtual environment as implemented via a virtual reality platform by one or more computing devices. The virtual environment includes virtual stores arranged along virtual streets. Virtual digital content is included in the stores, such as to initiate conversion of a good or service represented by the content. Configuration of the virtual environment is based on user, provider, and/or machine learning inputs.

Abstract: A machine is configured to automatically order consumable items for an account. For example, the machine accesses image input associated with a consumable item. The image input is recorded by a camera associated with a client device. The machine identifies an account based on an identifier of the client device. The machine determines a level of consumption of the consumable item for the account based on the image input. The machine, based on the level of consumption, automatically places an order for the consumable item, for the account. The machine, in response to the automatic placing of the order, causes display of a notification describing the automatically placed order in a user interface of the client device. A selection of the notification describing the automatically placed order for the consumable item causes display of an automatically generated request to specify a schedule of future automatic orders for the consumable item.

Abstract: A machine is configured to automatically generate listings for multiple items. For example, the machine receives, from a client device, two or more images and two or more descriptions. The two or more images depict two or more items. The two or more descriptions pertain to the two or more items. The machine matches one or more images of the two or more images to a description of the two or more descriptions. The one or more images depict an item of the two or more items. The description pertains to the item. The machine, based on the matching, generates a listing of the item. The listing includes the one or more images depicting the item, and the description pertaining to the item. The machine causes display of the listing of the item in a user interface.

Abstract: Methods, systems, and media for lot classification are disclosed. In one example, a classification system for identifying lot listings receives a description for a listing in a publication system, identifies a string in the listing, identifies a quantity word or digit in the string, and converts an identified quantity word into digit form. A normalized string is tokenized to produce tokens, the tokenizing of the normalized string including splitting the normalized string into a series of substrings using a sequence of delimiters. For each substring, an additional split is performed by separating any digit from any other adjacent character, unless that character is another digit, and maintaining an internal character order of each split substring to produce a flattened list of tokenized tokens.

Abstract: A visual search recommendation engine utilizes an image quality indication model for a visual search recommendation. Specifically, the visual search recommendation engine receives a search image as a search query at a search engine. The visual search recommendation engine provides the search image as an input into the image quality indication model, which is trained to output an image quality indication based on image aspects of the search image. A plurality of images are identified from an image corpus. The visual search recommendation engine determines an image similarity based on a comparison between the plurality of images from the image corpus and the search image. The image quality indication and the image similarity indicate a search query performance for the search image. A first image exceeding the search query performance is identified. The first image is provided for display at the search engine.

Abstract: Storage space is reclaimed by cleaning and compacting data objects where data objects are stored by immutable storage. A storage area of which space needs to be reclaimed is identified. Active and stale data objects stored in a storage area are identified, and only active data objects are transferred to a shadow storage area from the storage area when recovering storage space. I/O operations can be fulfilled from the storage area and the shadow storage area. Compaction requests and I/O requests are throttled according to QOS parameters. Recovery of storage space does not cause a failure to meet performance requirements for any storage volume.

Abstract: In an example, a digital image comprising a representation of multiple physical objects is received at a client computer. The digital image is copied into a temporary canvas. The digital image is then analyzed to identify a plurality of potential object areas, each of the potential object areas having pixels with colors similar to the other pixels within the potential object area. A minimum bounding region for each of the identified potential object areas is identified, the minimum bounding region being a smallest region of a particular shape that bounds the corresponding potential object area. The pixels within a selected minimum bounding region are cropped from the digital image. The pixels within the selected minimum bounding region are then sent to an object recognition service on a server to identify an object represented by the pixels within the selected minimum bounding region.

Abstract: Systems and methods for generating tokenized reputation scores are described. In one example, a service provider system receives data describing user activity associated with a service provider account and determines that the user activity is eligible for a reputation reward of reputation tokens. The service provider system initiates a calculation of the reputation reward based on the data describing the user activity. Further, the service provider system verifies a transfer of reputation tokens to a blockchain account address associated with the service provider account, where the reputation tokens are based on the reputation reward calculated. The service provider system generates a reputation score based on an amount of reputation tokens associated with the blockchain account address and generates an indication of the reputation score. The indication of the reputation score is displayed in relation to a representation of the service provider account.

Abstract: Digital content view control is described as leveraging a hierarchical structure of objects defined within the digital content to control how those objects are rendered in a user interface. In one example, a user input is received to display a view of objects within digital content displayed in a user interface. In response, a data query module is configured to fetch data describing a hierarchical structure of the digital content. From this, a z-order determination module determines a z-order of objects included with the digital content. An object view generation module is also configured to generate object views depicting the objects included in the digital content. The object views, once rendered, support an ability to view positioning of objects within the hierarchy.
