Multi-hardware energy-consumption-oriented channel pruning method and related product

A multi-hardware energy-consumption-oriented channel pruning apparatus, comprising:

• a deletion module configured to rank importance of a filter in a to-be-pruned CNN model by using an FDD evaluation model based on a feature distribution of an original network model, delete a filter with a lowest importance ranking, and obtain a candidate first pruning model;
• a determining module configured to determine an energy consumption of the candidate first pruning model by using an energy consumption estimation model based on actual measured data;
• a processing module configured to perform trade-off processing on importance of a filter in the candidate first pruning model and the energy consumption of the candidate first pruning model by using a multi-objective evolutionary solving model, and obtain a low-energy-consumption pruning scheme corresponding to each hardware device;
• and
• a pruning module configured to prune the to-be-pruned CNN model by using the low-energy-consumption pruning scheme, and obtain a second pruning model corresponding to each hardware device.
