A centroid is generated for each cluster. Using the model performance metric data, a misclassification indicator arrow is generated for each misclassified data point. The misclassification indicator arrow indicates both the predicted class and the actual class. The clusters, the centroids, and the misclassification indicator arrow are displayed as a graphical visualization of the machine learning model. |

Generating and visualizing bias scores representing bias in digital segments within segment-generation-user interfaces
This disclosure relates to methods, non-transitory computer readable media, and systems that generate and visualize bias scores within segment-generation-user interfaces prior to executing proposed actions with regard to target segments. For example, the disclosed systems can generate a bias score indicating a measure of bias for a characteristic within a segment of users selected for a proposed action and visualize the bias score and corresponding characteristic in a segment-generation-user interface. In some implementations, the disclosed systems can further integrate detecting and visualizing bias as a bias score with selectable options for a segmentation-bias system to generate and modify segments of users to reduce detected bias. |

Distributed database configuration
Replicas are selected in a large distributed network, and the roles for these replicas are identified. In one example, a leader is selected from among candidate computing dusters. To make this selection, an activity monitor predicts or monitors the workload of one or more clients. Different activities of the workload are given corresponding weights. The delay in performing requested activities, modified by these weights is found, and the candidate leader with the lowest weighted delay is selected as the leader. |

Distributed transaction management method and system
A distributed transaction in which appropriate patterns are combined without modifying implementation of a management system even when a service characteristic of a participating system changes. A management system receives input of a distributed transaction flow defining respective call sequential numbers of participating systems and service characteristic information representing respective service characteristics of the participating systems. The management system specifies an applied pattern for each of the participating systems based on pattern information including information for each pattern that represents a constraint condition of a service characteristic of a participating system as a call target. The applied pattern is a pattern satisfying the constraint condition corresponding to the service characteristic of the participating system. The management system generates a pattern-applied call program for each of the participating systems, and generates a distributed transaction program based on the pattern-applied call programs and a call sequence of the participating systems. |

Methods and systems for no fail searching
The method of no fail searching may include receiving a set of keywords from an input set of search fields within a GUI, retrieving a set of search results based on the set of keywords from the input set of search fields, organizing the set of search results according to a set of content types, ranking each search field according to the set of content types, removing the lowest ranked search field from the set of keywords to create a broadened set of search fields when at least one content type has zero results, repeating the retrieving, organizing, ranking, and removing steps until either each content type contains a threshold amount of search results or all search fields have been removed, wherein the broadened set of search fields is used as the input set of search fields in subsequent retrieving steps. |

Method and system for ranking plurality of digital documents
A method and server for ranking a plurality of documents are disclosed. The method includes determining, by the server, for each document from the plurality of documents a proximity value between a respective document vector and an other document vector. A given proximity value for a respective document being indicative of a similarity between (i) the respective document and (ii) at least one other one from the plurality of documents. The method also comprises using, by the server, the proximity values of the plurality of documents for ranking the plurality of documents. |

Data query method, apparatus and device
A method including obtaining resource overheads according to feature information of a received query request; according to the resource overheads and a compute node resource, dynamically adjusting a compute node in a resource pool; and querying, by using the compute node, data corresponding to the query request. A compute node in a resource pool may be dynamically adjusted, so that the compute node in the resource pool may process all the received query requests, and therefore, the processing efficiency and a resource utilization rate of the compute node are more effectively improved, such that the compute node may more efficiently perform parallel processing on the multiple query requests, and the utilization rates of a CPU resource, a memory resource and a network bandwidth resource are increased, thus achieving better effect from the perspectives of overall computing resource and user query load and improving the usage experience of a user. |

Low-latency database system
A database system comprised of a decoupled compute layer and storage layer is implemented to store, build, and maintain a canonical dataset, a temporary buffer, and an edits dataset. The canonical dataset is a set of batch updated data. The data is appended in chunks to the canonical dataset such that the canonical dataset becomes a historical dataset over time. The buffer is a write ahead log that contains the most recent chunks of data and provides atomicity and durability for the database system. The edits dataset is the set of data that contains edits such as cell mutations, row appends and/or row deletions. The database system enables users to make cell or row-level edits to tables and observe those edits in analytical systems or downstream builds with minimal latency. |

Cross-language search
In accordance with one disclosed method, a computing system may receive, via a first version of an application presenting an interface in a first language, a first query entered in a second language different from the first language. The computing system may search resources accessible to a second version of the application to identify at least a first resource corresponding to the first query, the second version of the application being in the second language. Based at least in part on a result of the searching, an indication of the first resource may be returned to the interface. |

Policy driven data placement and information lifecycle management
A method, apparatus, and system for policy driven data placement and information lifecycle management in a database management system are provided. A user or database application can specify declarative policies that define the movement and transformation of stored database objects. The policies are associated with a database object and may also be inherited. A policy defines, for a database object, an archiving action to be taken, a scope, and a condition before the archiving action is triggered. Archiving actions may include compression, data movement, table clustering, and other actions to place the database object into an appropriate storage tier for a lifecycle phase of the database object. Conditions based on access statistics can be specified at the row level and may use segment or block level heatmaps. Policy evaluation occurs periodically in the background, with actions queued as tasks for a task scheduler. |
