New 'onóna' technique boosts Transformer language model expressiveness

Researchers have introduced "onóna," a novel two-table parameterization technique for Transformer language models that enhances output expressiveness while maintaining input-output weight sharing. This method, which involves averaging two embedding tables and combining their softmax distributions with a token-conditioned gate, has demonstrated improvements in validation loss and perplexity across various architectures and scales. Evaluations showed that onóna lowered loss in 11 out of 12 comparisons and improved accuracy on downstream tasks in 10 out of 12, with a modest increase in parameter cost. AI

IMPACT This technique could lead to more efficient and expressive language models, potentially improving performance on various downstream NLP tasks.

    onóna: Twin Embeddings with Tied Unembeddings

    A two-table weight-sharing method for Transformer language models improves output expressiveness and reduces validation loss and perplexity across several architectures and scales at the cost of an extra embedding table and vocabulary projection.
