Abstract: A system and method reduces or minimizes the number of characteristic values required to evaluate a rule by selecting elements of the rule in an order most likely to allow evaluation of the rule without requiring evaluation of other elements of the rule. The selection may be a function of one or both of the structure of the rule and the probability that an element will resolve to a particular value of true or false.

Abstract: Systems, methods, storage media, and computing platforms for context-based data retrieval are disclosed. Exemplary implementations may: perform upfront analysis of the user's context; retrieve an optimal set of user context metadata as the initial read operation; render a user interface that displays user context metadata; retrieve end user selected relevant data as part of the read operation; render a user interface that displays only relevant data to the end user.

Abstract: Systems, methods, and storage media for providing navigation directions are disclosed. Exemplary implementations may: receive, by a field programmable gate array (FPGA), a first set of data from at least one sensor, the FPGA and the at least one sensor included in a wearable device worn by a user, perform at least one of a max-pooling operation and a convolution operation on the first set of data to produce processed data; transmit the processed data to a remote server to cause the remote server to train a machine learning model using the processed data to compute at least one weight, at least one layer, and at least one hyperparameter of the machine learning model; receive, from the remote server, a copy of the metadata file; and store the metadata file on the wearable device.

Abstract: Systems, methods, storage media, and computing platforms for managing data files are disclosed. Exemplary implementations may: receive an itinerary creation request specifying a destination city and a date; identify a retention policy for data records associated with the destination city; calculate a retention period end date based on the retention policy; format a file name according to a predetermined naming scheme; create a file having the file name in a file system; and store a data record corresponding to the itinerary creation request in the file.

Abstract: An example method includes receiving a data set, generating a topological representation using topological data analysis, at least one metric-lens combination, and the data set, the representation including a plurality of nodes, each of the nodes having one or more data points as members, receiving a new data point, determining distances between the new data point and at least some of the one or more data points, locating the new data point in a location relative to one or more of the nodes using the distances, identifying a subset of the data points closest to the location of the new data point, comparing the subset of the data points to at least some information regarding the new data point to identify a regime, and generating a report indicating a model associating factors associated with the subset of the data points with the new data point for predicting future outcomes.

Abstract: A role passing and persistence mechanism that implements role-based access control at a container level is disclosed. In one implementation, the role passing and persistence mechanism provides one or more RBAC services. Functions provided by the role passing and persistence mechanism include role validating, role persisting and role administration. The role passing and persistence mechanism is used to persist role information for a session between a client and a container for any type of client. No matter which adaptor a client uses to connect to the container, the role passing and persistence mechanism provides a uniform method of passing role information to the container such that persisted role information can be used by any service hosted by the container after the session is established and the role information has been persisted.

Abstract: An approach for managing functionalities within a system generally involves the use of indicators, such as privileges, that are associated with the functionalities. Each functionality is associated with an indicator that is used to determine whether the associated functionality is available for use by an end user. A determination is made that one or more particular functionalities are to be associated with the response because the particular indicator is included in the set of indicators and corresponds to the one or more functionalities. If the system includes functionalities for which indicators are not included in the set of indicators, those functionalities are not reflected in the response. The response is sent so that information regarding the one or more particular functionalities can be displayed via a user interface. In some implementations, an access control mechanism can use privileges for determining functionality availability and privileges for determining user access.

Abstract: An access control mechanism that implements access control at a container level is disclosed. In one implementation, the access control mechanism provides one or more access control services, and registers these services with a container. Once registered, the access control services are exposed to other applications in the container, and those applications can invoke the services to have the access control mechanism implement access control on their behalf. The access control mechanism implements access control for all applications within the container; thus, the applications do not need to implement their own access control mechanisms. In addition, the access control mechanism is not an operating system component. Thus, by relying on the access control mechanism for access control functionality, the applications are not relying on any operating system component. As a result, the applications, the container, and the access control mechanism can be ported to and run on other operating systems/platforms.
