Systems and methods for out-of-distribution classification
An embodiment proposed herein uses sparsification techniques to train the neural network with a high feature dimension that may yield desirable in-domain detection accuracy but may prune away dimensions in the output that are less important. Specifically, a sparsification vector is generated based on Gaussian distribution (or other probabilistic distribution) and is used to multiply with the higher dimension output to reduce the number of feature dimensions. The pruned output may be then used for the neural network to learn the sparsification vector. In this way, out-of-distribution detection accuracy can be improved. |

In response to a request for operational information regarding some or all of the devices, the system reads at least one of the volumes, and approximates the values of the data over a specified period of time. In some embodiments, the data may be buffered prior to storage, and a jitter analyzer determines whether the incoming data is anomalous relative to a baseline, which may be determined using related data sets. |

Detection of layout table(s) by a screen reader
Described herein is a system and method for detecting a layout table by a screen reader. Information regarding a document being displayed by an application is received from an application programming interface of a user interface automation system that provides information regarding user interface elements of application and/or the application. The information includes an indication that the document comprises a table. A determination is made as to whether the table is a data table or a layout table based upon the received information using a rule-based heuristic. When it is determined that the table is a layout table, presentation information associated with the layout table can be skipped over, and, cell data content within the layout table provided. Thus, for a determined layout table, the system and method allow the screen reader to act as if the containing table doesn't exist, but still read the content. |

Fast in-memory technique to build a reverse CSR graph index in an RDBMS
In an embodiment, a computer obtains a mapping of a relational schema of a database to a graph data model. The relational schema identifies vertex table(s) that correspond to vertex type(s) in the graph data model and edge table(s) that correspond to edge type(s) in the graph data model. Each edge type is associated with a source vertex type and a target vertex type. Based on that mapping, a forward compressed sparse row (CSR) representation is populated for forward traversal of edges of a same edge type. Each edge originates at a source vertex and terminates at a target vertex. Based on the forward CSR representation, a reverse CSR representation of the edge type is populated for reverse traversal of the edges of the edge type. Acceleration occurs in two ways. Values calculated for the forward CSR are reused for the reverse CSR. Elastic and inelastic scaling may occur. |

Real-time database performance tuning
Techniques are described for enabling real-time database performance measurement and tuning in a service provider network. To efficiently test one or more proposed configuration changes to a database in a service provider network, a database service is able to create a replicated copy of the database in an environment that mirrors that of the primary database. The database service then automatically causes database traffic destined for the primary database to be routed to both the primary database and the test database. Once the test database is created and traffic is routed to both databases, the database service obtains performance data by monitoring performance of both the primary database and the test database over a period of time. Based on the obtained performance database, the database service can automatically determine which of the primary database and the test database is exhibiting better performance. |

Software testing in parallel threads with a record-locking database
Test cases written to test a software application can be dynamically distributed among different sets of test cases that can be executed simultaneously in different parallel threads, thereby speeding up testing relative to executing the test cases sequentially in a single thread.

Locking individual database records can reduce and/or eliminate the chances that a test case in one parallel thread will be unable to access a record in the database because another test case in another parallel thread is simultaneously accessing the same database. |
