Outline

Building on the success of CLIP's prompt tuning, we propose Spotlighter, a lightweight token selection framework that simultaneously improves accuracy and efficiency by removing redundant or weakly correlated features that incur unnecessary computational costs. Spotlighter evaluates the activation of each visual token at both a sample-by-sample and semantic-by-sense level, retaining only the top-scoring tokens for downstream predictions. A class-specific semantic memory bank of learned prototypes enhances this selection, ensuring semantic representativeness and compensating for discarded features. Furthermore, we introduce a two-stage ranking mechanism that dynamically weights token-prototype interactions to prioritize informative cues. Across 11 few-shot benchmarks, Spotlighter improves harmonic mean accuracy by up to 11.19% over CLIP and achieves up to 0.8K FPS improvement with only 21 additional parameters. These results establish Spotlighter as an effective and scalable baseline for prompt tuning. The code is available at https://github.com/greatest-gourmet/Spotlighter .
