Abstract: Some embodiments include a workflow authoring tool that accesses a text string representation of a workflow and a text string representation of at least a data processing operator type. The workflow authoring tool enables definition of one or more data processing operator types that can be referenced in defining the machine learning workflow. When scheduling a workflow, the text string representation of the workflow can be parsed and traversed to generate an interdependency graph of one or more data processing operators. The text string representation of the data processing operator type can identify operator attributes associated with the data processing operator type.

Abstract: Some embodiments include an experiment management interface for a machine learning system. The experiment management interface can manage one or more workflow runs related to building or testing machine learning models. The experiment management interface can receive an experiment initialization command to create a new experiment associated with a new workflow. A workflow can be represented by an interdependency graph of one or more data processing operators. The experiment management interface enables definition of the new workflow from scratch or by cloning and modifying an existing workflow. The workflow can define a summary format for its inputs and outputs. In some embodiments, the experiment management interface can automatically generate a comparative visualization at the conclusion of running the new workflow based on an input schema or an output schema of the new workflow.

Abstract: Some embodiments include a method of machine learner workflow processing. For example, a workflow execution engine can receive an interdependency graph of operator instances for a workflow run. The operator instances can be associated with one or more operator types. The workflow execution engine can assign one or more computing environments from a candidate pool to execute the operator instances based on the interdependency graph. The workflow execution engine can generate a schedule plan of one or more execution requests associated with the operator instances. The workflow execution engine can distribute code packages associated the operator instances to the assigned computing environments. The workflow execution engine can maintain a memoization repository to cache one or more outputs of the operator instances upon completion of the execution requests.

Abstract: A copper-clad aluminum composite wire that can reduce an amount of copper to be used. A structure of the copper-clad aluminum composite wire includes: a wire made of an aluminum material, where a surface of the wire made of an aluminum material is sequentially provided with an intermediate metal layer and a copper layer; and assuming that a thickness of the copper layer is t1, a density of the copper layer is ?1, a thickness of the intermediate metal layer is t2, a density of the intermediate metal layer is ?2, a radius of the wire made of an aluminum material is R, and a density of the wire made of an aluminum material is ?3, t 1 = ( R + t 2 ) 2 + K 1 × ( t 2 2 + 2 ? ? t 2 × R ) ? ? ? 2 + K 1 × R 2 ? ? 3 ( 1 - K 1 ) × ? 1 - R - t 2 , where 0.02?K1?0.12. The copper-clad aluminum composite wire can be widely applied to the communication industry.
