Researchers have investigated the impact of temporal sampling frequency on end-to-end autonomous driving trajectory prediction models. They found that while dense frame sampling is often assumed to improve performance, this is not always the case. Smaller models often perform best with lower or intermediate sampling frequencies, suggesting that dense sampling can introduce redundant information and noise that burdens models with limited capacity. Larger, vision-language-model-style architectures, however, continued to improve performance even at the highest tested sampling frequencies. AI
