Power Law Formula for LLM Loss
The simplest mathematical relationship representing the loss of a model, , given a specific variable of interest, , is defined by the power law equation: . In this formula, and are parameters that must be estimated empirically. Despite being a simple function, it has successfully interpreted the scaling capabilities of both language models and machine translation systems when scaling model size () or training dataset size ().

Power Law Formula for LLM Loss
Improved Power Law for LLM Loss with Irreducible Error
A research team is developing a series of language models. They systematically increase the number of model parameters and measure the final test loss for each model. They observe a consistent trend: as the number of parameters grows, the test loss steadily decreases. However, the amount of improvement (loss reduction) becomes progressively smaller for each subsequent increase in parameters. Which of the following mathematical forms would be the most straightforward initial choice to model this observed relationship between model size and loss?

Two language models, Model A and Model B, have their performance (loss, L) modeled as a function of a resource
x(wherex > 1). The relationship for each is described by a power law equation:- Model A:
L(x) = 0.5 * x^-0.1 - Model B:
L(x) = 0.5 * x^-0.2
