idbfs has posted this link already but did not explain that Shalizi provides a deep theoretical explanation for why universal source coding (does not require information about symbol distribution or statistics) such as Lempel ziv derived compression algorithms can serve as powerful language models if practical restrictions on them such as dictionary and input corpus size are lifted. This is a good example of how old methods can be pushed quite far if similar resources were devoted to them. Who knows, they might even posses advantages hitherto unmet due to a lack of exploring at larger scales. That said, Transformers have a number of practical advantages. The learned projection matrices in attention lend Transformers a dynamic adaptability with respect to learned patterns that help make them programmable by their context, able to work out patterns present in context zero shot and on the fly. gzip based language models will be limited to their dictionary of patterns. The underlying vector space of neural language models also makes semantics more readily learnable (driving novel synthesis such as neologisms and more) while feed forward layers can learn a large range of computations. http://bactra.org/notebooks/nn-attention-and-transformers.html#gllz http://bactra.org/notebooks/nn-attention-and-transformers.ht...
