3.1.3 Annealing Data

  1. How did Llama 3 use annealing to judge the value of a small dataset?
    Take a half-trained 8B model, anneal its learning rate to zero over 40B tokens with 30% of the mix from the new dataset, and measure the effect: much cheaper than running scaling-law experiments for every small dataset. Annealing on high-quality math helped the 8B model a lot but the 405B model negligibly.
