Abstract: A process is provided for preparing fertilizer. The process includes the steps of combining a titanium composition and a silicon composition to yield a mixture, removing heavy metals from the mixture, controlling conductivity of a quantity of water in the mixture to below a predetermined amount, adding other materials to the mixture in a predetermined ratio, adding oxygen to the mixture, vibrating the mixture to minimize sticking, irradiating the mixture, and mixing the mixture with a high speed pump.

Abstract: Provided is a method and system for uniform execution of feature extraction. The method comprises: acquiring a feature extraction script for defining a processing logic related to feature extraction; analyzing the feature extraction script to generate an execution plan for feature extraction; and executing the generated execution plan by a local machine or a cluster based on a feature extraction scene. Based on the method and system, feature extraction can be uniformly executed at various feature extraction scenes.
