Abstract: A method for interaction between devices based on a pointing operation and an electronic device. The electronic device may be a mobile phone or the like. In the method, a pointing operation performed by a user from a handheld device to a target device is detected via an acceleration sensor, a gyroscope, an IMU, a camera, or the like of the handheld device, and a wireless positioning function of the handheld device is triggered. When it is identified that an axis of the handheld device intersects or approximately intersects with the target device, at least one type of feedback such as visual feedback, sound feedback, and vibration may be provided on the handheld device and/or the target device, login account information and device information of the target device are transmitted to the handheld device, and a target device control window is displayed on the handheld device.

Abstract: Described are devices and associated methods of producing extracellular matrix (ECM) sheet devices with strengthened mechanical properties due to the selective retention of muscle tissue layers during processing.

Abstract: A system for converting a machine learning algorithm includes: a programmatic interface layer configured to construct a data-flow diagram of an original machine learning algorithm based on a preset data flow generation tool; an operator placement and evaluation module configured to calculate placement costs of each operator in the data-flow diagram when the operator is executed by different participants; a data-flow diagram dividing and scheduling module configured to divide the data-flow diagram into multiple sub-diagrams according to the placement costs, and schedule each of the sub-diagrams to a target participant for execution; and a compilation and execution layer configured to compile the sub-diagrams into a new data-flow diagram based on a greedy algorithm strategy, and generate an instruction for each operator in the new data-flow diagram to obtain a distributed privacy protection machine learning algorithm.

Abstract: The present disclosure provides a method and an apparatus for publishing product information. The present disclosure provides a method for publishing product information. Based on a stored search click log of buyers, correlation information between inquiry words and categories in the search click log is calculated. A keyword input by the seller is matched to the inquiry words. The keyword may be a word or a phrase that includes one or more words. If the keyword is matched to at least one inquiry word, at least one category corresponding to the matched inquiry word is obtained based on the correlation information. The product information is stored under one or more categories of the obtained categories. The present techniques improve the accuracy rate of recommended categories to the seller and the return rate of the published product information.

Abstract: The present disclosure provides techniques to rank search results. The techniques may include acquiring a set of primitive characteristics and extracting effective characteristics from the set of primitive characteristics based on historical transaction data. The effective characteristics include characteristics that can have an influence on ranking of search results. The techniques may also include determining an initial weight of each of the effective characteristics based on the historical transaction data, and training the initial weight using the historical transaction data and a predetermined training model to obtain a final weight. Based on the final weight, the search results may be ranked. In some aspects, the techniques may also optimize the ranking to ensure the objectivity and accuracy of ranking results.
