Abstract: Techniques are provided for using machine learning techniques to identify predictive features and predictive values for each feature. In one technique, a model is trained based on training data that comprises training instances, each of which corresponds to multiple usage-based features of an online service by a user. For each usage-based feature in a subset of the usage-based features, the model is used to generate a dependency graph, a histogram is generated, and an optimized value is selected based on the dependency graph and the histogram. A user of the online service is identified, along with a usage value that indicates a level of usage, by the user, of a usage-based feature. A comparison between the usage value and an optimized value of the usage-based feature is performed. Based on the comparison, it is determined whether to present data about that usage-based feature to the user.

Abstract: A method for machining a drill with tilting blade slot structures for composite machining is provided. In the machining method, a face of the drill produces a downward component force for the inlet material to inhibit the inlet material from turning up; and a cutting edge inclination of an end surface at an outer turning point in a corner region of the drill is a positive value. The face and a flank are firstly partially ground in the corner region of the drill. The face at the outer turning point is ground with a grinding wheel to obtain two tilting blade slot structures. After grinding, a new face and a new cutting edge are obtained; and the cutting edge inclination on the end surface formed by the new cutting edge and a reference plane is a positive angle.

The sampling model may be employed to determine objects in the file system based on a traversal of the file system. The sampling model may be employed to determine metrics associated with the alternate data streams (ADSs) included in the objects such that each of the objects that includes a separate main data stream and the ADSs may be associated with data blocks and the ADSs may each be associated with other data blocks. The sampling model and the query may be employed to sample the objects to provide partial results such that the sampling may be distributed between the objects based on the sampling model and the metrics. A result to the query may be provided based on the partial results.

Abstract: A technical problem of multi-objective optimization of job applications redistribution in an online connection network system is addressed by incorporating monetary value of job applications as a signal into a ranker for ranking jobs with respect to a member profile in job search and recommendations. The monetary value of job applications is used in addition to the relevance signal and is determined by executing a machine learning model that accounts for the covariates that could impact monetary value of an application for a job.

Abstract: Planarizing and spin-on-carbon (SOC) compositions that fill vias and/or trenches on a substrate while planarizing the surface in a single thin layer coating process are provided. The compositions can planarize wide ranges of substrates with vias or trenches of from about 20 nm to about 220 nm wide, and up to about 700 nm deep. These extraordinary properties come from the low molecular weight of the polymers used in the materials, thermally-labile protecting groups on the polymers, and a delayed crosslinking reaction.

Abstract: This disclosure is directed to a social networking server that includes different engines and databases to support the generation of visually meaningful electronic presentations that present member-provided data in one or more graphical and understandable charts and graphs. An electronic presentation includes one or more electronic documents where various ones of the electronic documents are generated from templates that specify the “look-and-feel” for a given type of electronic document. Rather than having to manually enter and design graphs and charts to present member-provided data in a meaningful way, the social networking server leverages the stored electronic document templates to create these charts and graphs. However, as there may be multiple systems involved in creating a given type of chart or graph, the social networking server is tasked with coordinating the efforts of these different systems.

Abstract: A special end cutting edge attached cutter for carbon fiber reinforced polymer/plastic with designable micro-tooth configuration, having an end cutting edge, a peripheral cutting edge with variation inverse helical groove, a peripheral cutting edge with constant inverse helical groove and a shank. Two parallel V-shaped chip pockets are designed on the end cutting edge of the cutter in two cutting edge directions which are symmetrical around a cutter axis as a center. The structure may enhance chip removal performance during high-speed milling of impenetrable slots and impenetrable windows, reduce wear of the end cutting edge, conduct configuration design for micro-teeth of the peripheral cutting edge, reduce the cutting thickness of the micro-tooth cutting edges, and effectively solve the problem of damage of the micro-tooth edges. A section of peripheral cutting edge with variation left-hand inverse helical flute angle is designed near the end cutting edge.
