Krony-PT is a compression technique for the GPT-2 language model, utilizing Kronecker Products to reduce the size of the model's MLP layers. This method systematically compresses the feed-forward layer matrices, resulting in smaller models with reduced computational requirements. Krony-PT introduces a modified Van Loan decomposition for initializing new factors and a pruning-based initialization trick. The technique compresses the original 124M parameter GPT-2 to models as small as 80M parameters, with the 81M model variant outperforming distilgpt2 on next-token prediction tasks. Krony-PT demonstrates competitive performance with other Kronecker Products-based compressed models, offering a balance between model size and performance.
