The measurement viewing angle multi-objective optimization method comprises: obtaining information on and positions of all positioning tools (4) of each link in a surgery process, and establishing a multi-objective minimization problem based on a decision variable; establishing a three-dimensional Cartesian coordinate system for each positioning tool (4); defining a non-interference margin function between the positioning tools (4), and at least two objective functions of minimization optimization; and setting constraint conditions to minimize the at least two objective functions at the same time.

Abstract: A tax category prediction model, which is trained using a tax category prediction dataset, provides a tax category prediction for an item having an item listing. The tax category prediction model enhances the ability and accuracy of identifying a tax category associated with an item for sale via the online marketplace (e.g., identifying the tax category before the item is offered for sale via the online marketplace). The tax category prediction dataset is generated based on one or more of a text embedding, an image embedding, another type of embedding, or a combination thereof. The text embedding may be identified by applying a natural language processing model to a text string of the item listing. The natural language processing model may comprise bidirectional encoder representations from transformers (BERT).

Abstract: The systems and methods perform simulations in a systematic way as to minimize redundant data fetching and computations and reduce run-time. The systems and methods can cache information that can be used across multiple control strategies and speed up the process of simulation by several orders of magnitude. A business analyst can first generate a set of matching criteria that meets business intuition for the specific initiative and set of stores under analysis. A systematic approach in building similar sites models from control strategies that are combinations of this set of matching criteria can be applied to minimize data extraction and processing. The similarity function allows for the distance of each criterion to be combined linearly. Data for each matching criteria only needs to be extracted once but can be used in all control strategies that uses that criteria.
