Abstract: A cloaking device comprises an object-side, an image-side, a cloaked region between the object-side and the image-side. An object-side optical component and an object-side tilt correction (TC) component are positioned on the object-side, and an image-side optical component and an image-side TC component are positioned on the image-side. The cloaking device is tilted relative to an object positioned on the object-side such that light from the object is incident on the cloaking device at an acute angle. The object-side TC component redirects light from the object incident on the cloaking device such that the light propagates through the cloaking device generally normal to the object-side and image-side optical components. The image-side TC component redirects light propagating through the cloaking device back to normal to the object to form an image of the object on the image-side of the cloaking device which, if not for the TC components, would be distorted.

Abstract: In an example embodiment, a machine-learned model is trained to specifically identify anomaly points in time series data. The model is capable of being applied in parallel to many different time series simultaneously, allowing for a scalable solution for large scale online networks. The model classifies each data point in a specified time window and outputs rich contextual information for downstream applications, such as ranking and display of the anomalous data points.

Abstract: In an example embodiment, a machine-learned model is trained to rank anomaly points in time series data. The model is capable of being applied in parallel to many different time series simultaneously, allowing for a scalable solution for large scale online networks. The model outputs a ranking score for an input anomaly and allows for ranking of anomalies not just in the same time series but anomalies across multiple time series as well. This ranking can then be used to determine how best to present the ranked anomalies to users in a graphical user interface.

Abstract: In an example embodiment, a model is trained to specifically identify reversal points in data and then to rank these reversal points in order of importance. A reversal point shall be defined as a point in which a particular metric, specifically a first order derivative, crosses over from positive to negative or vice-versa. Users are more likely to be interested in abnormal and significant changes in data, and thus the machine-learned model is trained to evaluate a reversal point based on two dimensions: abnormality and significance.

Abstract: A resource pool processing method and apparatus, and a device, where the method includes obtaining a service template of a to-be-provisioned service, determining, based on the service template, first service-level agreement (SLA) information corresponding to the to-be-provisioned service, determining whether there is SLA information matching the service template on a management server, creating a new storage device based on the first SLA information and preset storage infrastructure when there is no SLA information matching the service template on the management server, creating a new virtual resource pool based on the new storage device, and associating the new virtual resource pool with a new SLA. Thereby, even when a physical pool occupied by another virtual pool on the management server is damaged, data running of the to-be-provisioned service is not affected, and data isolation is greatly improved.

Abstract: Methods are presented for providing dynamic search filter suggestions that are updated and ranked based on the user filter selections. One method includes detecting a query received in a user interface (UI), calculating, by a search-candidate model, first search results, and calculating, by a suggestions model, first filter suggestions for filter categories to filter responses to the query. The suggestions model is obtained by training a machine-learning algorithm utilizing pairwise learning-to-rank modeling. The first search results and the first filter suggestions are presented in the UI. When a selection in the UI of a filter suggestion is detected, the search-candidate model calculates second search results for the filter categories based on the query and the selected filter suggestion, and the suggestions model calculates second first filter suggestions based on the query and the selected filter suggestion. The second search results and the second filter suggestions are presented in the UI.

Abstract: In an example, for each feature of one or more features of a target sample data, feature values for one or more pseudo-samples are generated using, localized stratified sampling. The one or more pseudo-samples are fed into the trained machine learned model to obtain their prediction values. A piecewise linear regression model is trained using the one or more pseudo-samples and their prediction values, the piecewise linear regression model having two coefficients for each feature, a first coefficient describing prediction change when a corresponding feature value is increased and a second coefficient describing prediction change when a corresponding feature value is decreased. A top positive feature influencer is identified based on a feature of the one or more features of the target sample having a greatest magnitude of positive first coefficient or greatest magnitude of negative second coefficient.

Abstract: Devices and methods are described for reducing etching due to galvanic effect within a printed circuit board that may be used, for example, in a data storage device, such as a card-type data storage device. Specifically, a contact trace is coupled to a contact finger that has a substantially larger surface area than the contact trance, and that is configured to couple the data storage device to a host device. The contact trace is electrically isolated from the rest of the circuitry during a fabrication process. The contact finger and an exposed portion of the contact trace are plated with a common material to reduce galvanic etching of the contact trace during fabrication. The contact trace is then connected to an impedance trace though at least one of a component and a bond wire.
