What are LLM Presence and Frequency Penalties?
âď¸VIDEO DESCRIPTION âď¸
In this video, we explore two important parameters in Large Language Models (LLMs): Presence Penalty and Frequency Penalty. These settings are key to controlling how repetitive or diverse the model's output is. The Presence Penalty discourages the model from reusing words or phrases it has already mentioned, promoting a more varied and creative output. Meanwhile, the Frequency Penalty goes further by reducing the likelihood of repeating words that have already appeared multiple times, ensuring a broader vocabulary and less redundancy in the generated text.
We then compare these penalties with other commonly used parameters, like Temperature, Top-P, and Top-K. Temperature controls the overall randomness and creativity of the modelâs output, making it more or less predictable, but doesnât specifically target word repetition. Top-P, or nucleus sampling, selects words based on cumulative probability, focusing on high-probability words until a certain threshold is met. Top-K limits the modelâs choices to the top K probable words at each step, narrowing the selection pool. These parameters influence how creative or controlled the output is, but they donât directly manage repetition like the Presence and Frequency Penalties do.
