-适配 Transformer 结构:类似于 NLP 任务中的 token 化(tokenization),将连续动作值映射到离散 token,使得 Transformer 可以直接处理动作预测。 通过这种离散化,我们得到一个机器人N维动作对应的N个离散整数。不幸的是,OpenVLA backbone的tokenizer(Llama tokenizer)仅为微调期间新引入的token预留了100个“special tokens...
We are proud to distribute and contribute to a variety of open-source projects. Technologies for Data Science
In machine learning, large amounts of training data are often essential for getting good results. Many open-source machine learning projects either release only the model code (results reproducible if and only if you're Google), or a pre-baked model where the training conditions are unknown. ...
Consequently, there is a growing demand for high-performance, open-source video tokenizers as video-centric research gains prominence. We introduce VidTok, a versatile video tokenizer that delivers state-of-the-art performance in both continuous and discrete tokenizations. VidTok incorporat...
