Abstract
A method of pruning a pre-trained model comprises the steps of (a) constructing a stochastic super net and (b) training the stochastic super net to determine a particular candidate block selection that provides an optimal level of sparsity for each of the layers based upon a cost function. The stochastic super net generally represents a layer-wise search space with a fixed macro-architecture. A number of layers of the macro-architecture and input/output dimensions of each of the layers of the macro-architecture are essentially the same as the pre-trained model. Each layer comprises a plurality of candidate blocks. A sparsity of each of the candidate blocks in a respective layer is different. A training dataset used to train the pre-trained model is used to train the stochastic super net.
