What is recorded here?
Compressed continuous action chunks through discrete-cosine-transform-based tokenization before autoregressive learning, releasing a tokenizer trained across diverse robot embodiments and control rates.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
DCT, compression and subword/token modeling are inherited. Acquired delta is action-sequence encoding for VLA training, not invention of DCT or a universal tokenizer guarantee. Training-speed comparisons are workload-specific; FAST+ and pi0-FAST bundled.
