  • Publication number: 20170308846
    Abstract: This disclosure includes systems for regression-tree-modified feature vector machine learning models for utilization prediction in time-expiring inventory. An online computing system receives a feature vector for a listing and inputs the feature vector and modified feature vectors into a demand function to generate demand estimates. The system inputs the demand estimates into a likelihood model to generate a set of request likelihoods, each request likelihood representing a likelihood that the time-expiring inventory will receive a transaction request at each of a set of test price and test times to expiration. The system further trains a regression tree model based on a set of training data comprising each of the request likelihoods from the set and the test price and test time period to expiration used to generate the demand estimate that was used to generate the request likelihood.

  • Publication number: 20170310071
    Abstract: A method for generating femtosecond vortex beams with high spatial intensity contrast, where a noncollinearly pumped HG beam femtosecond laser generates femtosecond HG beam and a cylindrical lens mode converter converts the femtosecond HG beam to femtosecond LG vortex beam. The HG beam femtosecond laser comprises a pump source, a gain medium, a saturable absorption mirror as mode-locker, and an output coupler with a noncollinear angle between the laser beam and the pump beam in the gain medium, which enables the laser to generate pure, order-tunable femtosecond HG beams. Femtosecond vortex beams obtained after the cylindrical lens converter have high-intensity-contrast, and are topological charge-tunable.

  • Publication number: 20170300138
    Abstract: A conductive section (13) is disposed at an inclination of 30 degrees with respect to a pen body (10). When a pen tip (12) comes into contact with or proximity to a touch surface of a touch panel (2), an angle of inclination of a length direction of the conductive section (13) with respect to the touch surface of the touch panel (2) is an angle (60 degrees to 90 degrees) at which a difference between a position of contact or proximity of the pen tip (12) on or to the touch surface and a center of gravity of a distribution of the sizes of changes in capacitance as generated by the pen tip (12) coming into contact with or proximity to the touch surface becomes constant regardless of place on the touch surface. With this, even when the pen tip is sufficiently small, variations in positions of contact or proximity to be detected when the pen body is tilted can be reduced.
