ICLR 2026 Oral | 大道至简!斯坦福、英伟达、新国立联合推出InfoTok,用信息论重新定义高效视频分词
机器之心· 2026-03-30 06:52
Core Insights - The article discusses the introduction of InfoTok, an adaptive video tokenizer that utilizes information theory to optimize token allocation based on video content complexity, achieving a 2.3 times compression rate and 11 times faster inference speed compared to similar adaptive solutions [2][41]. Group 1: Motivation and Theory - Current visual tokenizers apply a fixed compression rate, leading to inefficient token allocation regardless of video complexity, which is not optimal [9][10]. - InfoTok aims to address this inefficiency by leveraging Shannon's information theory, which suggests that the amount of information dictates the number of tokens required for encoding [11][12]. - The ideal video tokenizer should achieve high compression rates, maintain high fidelity, and capture semantically meaningful content [12]. Group 2: Methodology - InfoTok employs two main components: the ELBO router, which determines the number of tokens to allocate, and the adaptive compressor, which encodes the data into a variable-length token sequence [19][23]. - The ELBO router uses a computable proxy to measure the predictability of video content, allowing for near-optimal token allocation based on content complexity [20][21]. - The adaptive compressor intelligently packages fixed-length embeddings into a variable-length token sequence, optimizing information retention and compression [25][26]. Group 3: Experimental Results - InfoTok demonstrated superior performance in video reconstruction benchmarks, achieving lossless reconstruction while saving 20% of tokens and outperforming ElasticTok at a 2.3 times compression rate [41][44]. - The framework consistently outperformed heuristic methods across all compression levels, showcasing significant improvements in reconstruction quality and inference efficiency [44][45]. - Visual results indicated that InfoTok dynamically adjusts token allocation based on scene complexity, effectively balancing compression and quality [38][39]. Group 4: Future Prospects - The principles behind InfoTok's information-theoretic framework could extend beyond video to other domains such as images and 3D scenes, suggesting a broader application of adaptive tokenization [48]. - The integration of adaptive tokenization into video generation pipelines could enhance both quality and efficiency, marking a significant advancement in AI video generation technology [48].
