RibonanzaNet

This model is in a future release of MultiMolecule, and is under development. This model card is not final and will be updated in the future.

Pre-trained model on RNA chemical mapping for modeling RNA structure and other properties.

Disclaimer

This is an UNOFFICIAL implementation of the Ribonanza: deep learning of RNA structure through dual crowdsourcing by Shujun He, Rui Huang, et al.

The OFFICIAL repository of RibonanzaNet is at Shujun-He/RibonanzaNet.

The MultiMolecule team is aware of a potential risk in reproducing the results of RibonanzaNet.

The original implementation of RibonanzaNet applied dropout-residual-norm path twice to the output of the Self-Attention layer.

By default, the MultiMolecule follows the original implementation.

You can set fix_attention_norm=True in the model configuration to apply the dropout-residual-norm path once.

See more at issue #3

The MultiMolecule team is aware of a potential risk in reproducing the results of RibonanzaNet.

The original implementation of RibonanzaNet does not apply attention mask correctly.

By default, the MultiMolecule follows the original implementation.

You can set fix_attention_mask=True in the model configuration to apply the correct attention mask.

See more at issue #4, issue #5, and issue #7

The MultiMolecule team is aware of a potential risk in reproducing the results of RibonanzaNet.

The original implementation of RibonanzaNet applies dropout in an axis different from the one described in the paper.

By default, the MultiMolecule follows the original implementation.

You can set fix_pairwise_dropout=True in the model configuration to follow the description in the paper.

See more at issue #6

The MultiMolecule team has confirmed that the provided model and checkpoints are producing the same intermediate representations as the original implementation.

The team releasing RibonanzaNet did not write this model card for this model so this model card has been written by the MultiMolecule team.

Model Details

RibonanzaNet is a bert-style model. RibonanzaNet follows the modification from the RNAdegformer where it introduces a 1D convolution with residual connection at the beginning of each encoder layer. Different from RNAdegformer, RibonanzaNet does not apply deconvolution at the end of the encoder layers, and updates the pairwise representation through outer product mean and triangular update.

RibonanzaNet is pre-trained on a large corpus of RNA sequences with chemical mapping (2A3 and DMS) measurements. Please refer to the Training Details section for more information on the training process.

Usage

The model file depends on the multimolecule library. You can install it using pip:

pip install multimolecule

Direct Use

Masked Language Modelling

You can use this model directly to predict chemical mapping:

>>> from multimolecule import RnaTokenizer, RibonanzaNetForPreTraining
>>> tokenizer = RnaTokenizer.from_pretrained("multimolecule/ribonanzanet")
>>> model = RibonanzaNetForPreTraining.from_pretrained("multimolecule/ribonanzanet")

RNA Secondary Structure Prediction

You can use this model to predict the secondary structure of an RNA sequence:

>>> import multimolecule  # you must import multimolecule to register models
>>> from transformers import pipeline
>>> predictor = pipeline("rna-secondary-structure", model="multimolecule/ribonanzanet")
>>> predictor("agcagucauuauggcgaa")

Downstream Use

Extract Features

Here is how to use this model to get the features of a given sequence in PyTorch:

from multimolecule import RnaTokenizer, RibonanzaNetModel


tokenizer = RnaTokenizer.from_pretrained("multimolecule/ribonanzanet")
model = RibonanzaNetModel.from_pretrained("multimolecule/ribonanzanet")

text = "UAGCUUAUCAGACUGAUGUUG"
input = tokenizer(text, return_tensors="pt")

output = model(**input)

Sequence Classification / Regression

This model is not fine-tuned for any specific task. You will need to fine-tune the model on a downstream task to use it for sequence classification or regression.

Here is how to use this model as backbone to fine-tune for a sequence-level task in PyTorch:

import torch
from multimolecule import RnaTokenizer, RibonanzaNetForSequencePrediction


tokenizer = RnaTokenizer.from_pretrained("multimolecule/ribonanzanet")
model = RibonanzaNetForSequencePrediction.from_pretrained("multimolecule/ribonanzanet")

text = "UAGCUUAUCAGACUGAUGUUG"
input = tokenizer(text, return_tensors="pt")
label = torch.tensor([1])

output = model(**input, labels=label)

Token Classification / Regression

This model is not fine-tuned for any specific task. You will need to fine-tune the model on a downstream task to use it for token classification or regression.

Here is how to use this model as backbone to fine-tune for a nucleotide-level task in PyTorch:

import torch
from multimolecule import RnaTokenizer, RibonanzaNetForTokenPrediction


tokenizer = RnaTokenizer.from_pretrained("multimolecule/ribonanzanet")
model = RibonanzaNetForTokenPrediction.from_pretrained("multimolecule/ribonanzanet")

text = "UAGCUUAUCAGACUGAUGUUG"
input = tokenizer(text, return_tensors="pt")
label = torch.randint(2, (len(text), ))

output = model(**input, labels=label)

Contact Classification / Regression

This model is not fine-tuned for any specific task. You will need to fine-tune the model on a downstream task to use it for contact classification or regression.

Here is how to use this model as backbone to fine-tune for a contact-level task in PyTorch:

import torch
from multimolecule import RnaTokenizer, RibonanzaNetForContactPrediction


tokenizer = RnaTokenizer.from_pretrained("multimolecule/ribonanzanet")
model = RibonanzaNetForContactPrediction.from_pretrained("multimolecule/ribonanzanet")

text = "UAGCUUAUCAGACUGAUGUUG"
input = tokenizer(text, return_tensors="pt")
label = torch.randint(2, (len(text), len(text)))

output = model(**input, labels=label)

  abstract     = {Prediction of RNA structure from sequence remains an unsolved problem, and progress has been slowed by a paucity of experimental data. Here, we present Ribonanza, a dataset of chemical mapping measurements on two million diverse RNA sequences collected through Eterna and other crowdsourced initiatives. Ribonanza measurements enabled solicitation, training, and prospective evaluation of diverse deep neural networks through a Kaggle challenge, followed by distillation into a single, self-contained model called RibonanzaNet. When fine tuned on auxiliary datasets, RibonanzaNet achieves state-of-the-art performance in modeling experimental sequence dropout, RNA hydrolytic degradation, and RNA secondary structure, with implications for modeling RNA tertiary structure.Competing Interest StatementStanford University is filing patent applications based on concepts described in this paper.
