Abstract: Shaded bid values may be determined and/or submitted to one or more auction modules for participation in auctions. Auction information including at least one of impression indications associated with the auctions, sets of features associated with the auctions, the shaded bid values associated with the auctions, etc. may be stored in a database. A machine learning model may be trained using the auction information to generate a first machine learning model with feature parameters associated with features. A bid request, indicative of a second set of features, may be received. The first machine learning model may be used to determine win probabilities and/or expected bid surpluses associated with multiple shaded bid values based upon one or more feature parameters, of the feature parameters, associated with the second set of features. A shaded bid value for submission may be determined based upon the win probabilities and/or the expected bid surpluses.

Abstract: Disclosed is a device and method for reducing combustion cone fallout propensity and stabilizing loss of tobacco from ends. Firstly, the right installation positioning hole is moved rightwards to extend the distance of the separation zone. Meanwhile, the vibration mechanism is redesigned so that it is enabled to move toward the lower right of the material groove body. Therefore, there is enough space to install the separation screen in the separation zone. Finally, the separation screen is installed. The tobacco scraps are separated out when they pass through the separation screen, thus reducing cone dropping when the cigarette burns, stabilizing the amount of dropping tobacco at the end, and improving the smoking experience and recognition of customers with regard to cigarette products.

Abstract: One or more computing devices, systems, and/or methods for assessing riskiness of a domain are provided. For example, a content request is received from a content provider service that hosts a website associated with a domain. The content request is evaluated to identify request features. Feature scores are assigned to the request features using labeled feature data. The feature scores are aggregated to generate a content request risk score corresponding to a riskiness of the content request corresponding to fraud, such as domain spoofing. The content request risk score along with other content request risk scores of content requests associated with the content provider service are aggregated to create a content provider risk score corresponding to a riskiness of the content provider service, such as a risk of the domain being fraudulent. The content provider risk score is used to either block or process the content request.

Abstract: Shaded bid values may be determined and/or submitted to one or more auction modules for participation in auctions. Auction information including at least one of impression indications associated with the auctions, sets of features associated with the auctions, the shaded bid values associated with the auctions, etc. may be stored in a database. A machine learning model may be trained using the auction information to generate a first machine learning model with feature parameters associated with features. A bid request, indicative of a second set of features, may be received. The first machine learning model may be used to determine win probabilities and/or expected bid surpluses associated with multiple shaded bid values based upon one or more feature parameters, of the feature parameters, associated with the second set of features. A shaded bid value for submission may be determined based upon the win probabilities and/or the expected bid surpluses.

Abstract: An optical actuator, including: a base; a lens module comprising two first side surfaces opposite each other; and a plurality of shape memory alloy wires forming two wire groups, the two wire groups being disposed on the two first side surfaces, respectively, wherein two ends of each shape memory alloy wire are fixed to a base-end fixing device and a lens-end fixing device, respectively; and the direction of the resultant force acting on the lens module by the two wire groups is consistent with the direction of the optical axis of the lens module, so that the lens module is driven to move along the direction of the optical axis of the lens module by means of expansion and contraction of the shape memory alloy wires of the two wire groups.
