A system quality risk coefficient is introduced, a comprehensive optimization parameter is generated, a target process parameter is obtained through mapping according to the comprehensive optimization parameter, finally, a cooperative control instruction subjected to environment interference compensation is generated based on the target parameter and issued to an execution unit, and dynamic cooperative optimization of the stamping efficiency and the process quality is achieved.

A big data job planner uses online machine learning to recommend algorithms for each job in a sequence to enhance various aspects of job execution. A job algorithm prediction server processes a job's pre-runtime metadata to create predictions of relevant big data job behavior characteristics based on previously learned models of the corresponding big data system's behavior and provides a recommended algorithm to the client big data system. After the big data job is executed, the job metadata coordinator persists pre-runtime metadata and corresponding post-runtime big data job behavioral metadata actually observed. Repeatedly through time, online machine learning is performed on this sequence of job behavior metadata so that machine learning models will learn difficult-to- recognize phenomena, as well as, changes in system behavior through time. Unlike statically coded rules, the system models changing patterns and behaviors, enabling the algorithm predictions to remain useful, thereby enhancing big data system quality.

The present application relates to the technical field of data transaction, in particular to a data transaction intelligent quality evaluation method and system based on multi-dimensional cooperation. The quality evaluation method comprises the following steps: S1, a data transaction platform receives a data product to be traded submitted by a data seller, and matches a corresponding data buyer according to the information of the data product; S2, quality detection is performed on the data product to identify data with quality problems. By identifying the behavior information of the data buyer, the preferred quality demand of multiple different data buyers is obtained, and according to the behavior information of multiple different data buyers, mutual cross verification is performed to obtain the basic demand (i.e. implicit quality demand) of the scene where the data product is located. The basic demand and the preferred quality demand jointly divide the scoring weight proportion of different data buyers in the scene where the data product is located, so as to realize the scene quality score evaluation for the scene where the data product is located, and reduce the generation of value mismatch phenomenon.
