Researchers have developed a bigram model with power-law token statistics to analytically study neural scaling laws. This model, using fixed random embeddings as a proxy for representational capacity, allows for the derivation of scaling laws for prediction regret based on model width, vocabulary size, and the Zipf exponent. The theoretical findings align with recent accounts focusing on optimization dynamics and suggest that heavy-tailed language statistics may be a fundamental driver of both optimization- and capacity-driven scaling. Experimental results on natural language datasets like WikiText2 and OpenWebText closely match the predicted scaling curves. AI
