This invention provides a dual-stream prefetch hardware system and vector operation method for vector processing. The system includes a computational path for performing regular vector operations in response to vector operation instructions, a computational path for performing streaming vector operations in response to predefined streaming operation instructions, and a storage unit. The system includes a streaming instruction control unit and a vector streaming processing core. The streaming instruction control unit is used to identify predefined streaming operation instructions and is configured to close the computational path for regular vector operations when a predefined streaming operation instruction is detected to be fetched. The vector streaming processing core is used to perform streaming vector operations in response to predefined streaming operation instructions. This solution achieves hardware decoupling of dense layout operations and non-dense sparse streaming operations by building dual independent computational paths for regular vector operations and streaming vector operations, thereby effectively improving the overall operation efficiency and real-time performance.

A framework for interpreting machine learning models is proposed that utilizes interpretability methods to determine the contribution of groups of input variables to the output of the model. Input variables are grouped based on dependencies with other input variables. The groups are identified by processing a training data set with a clustering algorithm. Once the groups of input variables are defined, scores related to each group of input variables for a given instance of the input vector processed by the model are calculated according to one or more algorithms. The algorithms can utilize group Partial Dependence Plot (PDP) values, Shapley Additive Explanations (SHAP) values, and Banzhaf values, and their extensions among others, and a score for each group can be calculated for a given instance of an input vector per group. These scores can then be sorted, ranked, and then combined into one hybrid ranking.
