It is a subclass of the

an <code>AutoModelForSequenceClassification</code> as the reward model. The reward model should be trained on a dataset
of paired examples, where each example is a tuple of two sequences. The reward model should be trained to
predict which example in the pair is more relevant to the task at hand.</p> <p data-svelte-h="svelte-bkmbwh">The reward trainer expects a very specific format for the dataset. The dataset should contain two 4 entries at least
if you don’t use the default <code>RewardDataCollatorWithPadding</code> data collator.
