They then tested how well structure could be reconstructed and how the embeddings performed on protein function and localization benchmarks.","gist":"The paper compresses the latent space of the protein folding model ESMFold into smaller continuous and tokenized embeddings, called CHEAP, that keep structure information and work on function and localization tasks.","meaning":"Most protein machine learning representations capture either sequence or structure, with the other left implicit. The claim is that a discrete set of tokens describing an all-atom structure can be produced from a protein's sequence without a separate structure input. If it holds, such tokens could feed downstream uses such as generation, search and prediction, and make the representations of large models easier to use.","findings":["Continuous compression reduces the ESMFold latent space by 128 times along the channel and 8 times along the length while keeping structure information at under 2 Å accuracy.","The compressed embeddings perform competitively on protein function and localization benchmarks.","Discrete compression yields a tokenized all-atom structure vocabulary with high reconstruction accuracy."],"terms":[{"term":"tokenized all-atom structure vocabulary","means":"A fixed set of discrete symbols, like words in a dictionary, that together describe the three-dimensional positions of every atom in a protein."},{"term":"discrete compression","means":"Shrinking information into a limited set of distinct codes rather than continuous numerical values."},{"term":"reconstruction accuracy","means":"How closely the original protein structure can be rebuilt from its compressed representation."}],"basis":"abstract","abstractFrom":"europepmc","model":"claude-sonnet-5-5","writtenAt":"2026-10-13T05:32:53.913Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-13T05:32:53.913Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
