# Goldfish Loss
<div align="center">

</div>
We introduce goldfish loss, a new language modeling loss function that mitigates memorization of training data.
Specifically, goldfish loss pseudorandomly drops $1/k$ of total tokens seen (in the forward pass) during loss computation (i.e., it doesn't compute loss for these tokens), with k being a hyperparameter.
We show that the model finds it increasingly difficult to verbatim regurgitate training data even after 100 epochs. Please read our paper linked below for more details.
# Overview
The following checkpoints are from our paper titled Goldfish Loss: Mitigating Memorization in Generative LLMs [[paper link](https://arxiv.org/abs/2406.10209)].

### Description
- `standard-loss-llama-1B` and `control-llama-1B` are trained with the standard causal language modeling loss, which has the same exact specifications as the goldfish models.
- The control model differs only in the fact that it did not utilize the canaries dataset for memorization and was simply pre-trained on 20B Redpajama tokens.
- The Canaries dataset, which contains 2000 Wikidocs, is repeated 50 times throughout the pre-training. Thus, it contains around ~204M tokens in total (including padding).
# Technical Specification
Each checkpoint mentioned above used randomly initialized [TinyLLaMA-1.1B](https://huggingface.co/TinyLlama/TinyLlama_v1.1) architecture.
For pretraining details, please find check our [GitHub](https://github.com/ahans30/goldfish-loss) repository.
