BERT, which stands for Bidirectional Encoder Representations
from Transformers. Unlike recent language representation
models (Peters et al., 2018a; Radford et al., 2018), BERT is
designed to pre-train deep bidirectional representations from
unlabeled text by jointly conditioning on both left and right
context in all layers. As a result, the pre-trained BERT model
can be fine-tuned with just one additional output layer to
create state-of-the-art models for a wide range of tasks, such
as question answering and language inference, without
substantial task-specific architecture modifications. BERT is
conceptually simple and empirically powerful. It obtains new
state-of-the-art results on eleven natural language processing
tasks, including pushing the GLUE score to 80.5 (7.7 point
absolute improvement), MultiNLI accuracy to 86.7{\%} (4.6{\%}
absolute improvement), SQuAD v1.1 question answering Test F1
to 93.2 (1.5 point absolute improvement) and SQuAD v2.0 Test

explanation of model predictions, with mixed evidence on
whether attention can be used as such. While attention
conveniently gives us one weight per input token and is easily
extracted, it is often unclear toward what goal it is used as
explanation. We find that often that goal, whether explicitly
stated or not, is to find out what input tokens are the most
relevant to a prediction, and that the implied user for the
explanation is a model developer. For this goal and user, we
argue that input saliency methods are better suited, and that
there are no compelling reasons to use attention, despite the
coincidence that it provides a weight for each input. With
this position paper, we hope to shift some of the recent focus
on attention to saliency methods, and for authors to clearly
state the goal and user for their explanations.",

make inferences from a family of evo lutionarily related
sequences by fitting a model to each family independently. In
this work we combine the two paradigms. We introduce a protein
language model which takes as input a set of sequences in the
form of a multiple sequence alignment. The model interleaves
row and column attention across the input sequences and is
trained with a variant of the masked language modeling
objective across many protein families. The performance of the
model surpasses current state-of-the-art unsupervised
structure learning methods by a wide margin, with far greater
parameter efficiency than prior state-of-the-art protein
language models.Competing Interest StatementThe authors have

billions of known protein sequences6,7. Structural coverage is
bottlenecked by the months to years of painstaking effort
required to determine a single protein structure. Accurate
computational approaches are needed to address this gap and to
enable large-scale structural bioinformatics. Predicting the
three-dimensional structure that a protein will adopt based
solely on its amino acid sequence---the structure prediction
component of the `protein folding problem'8---has been an
important open research problem for more than 50
Despite recent progress10--14, existing methods fall far
of atomic accuracy, especially when no homologous structure is
available. Here we provide the first computational method that
can regularly predict protein structures with atomic accuracy
even in cases in which no similar structure is known. We
validated an entirely redesigned version of our neural
network-based model, AlphaFold, in the challenging 14th
Critical Assessment of protein Structure Prediction
(CASP14)15, demonstrating accuracy competitive with
experimental structures in a majority of cases and greatly
outperforming other methods. Underpinning the latest version
of AlphaFold is a novel machine learning approach that
incorporates physical and biological knowledge about protein
