+# Data2Vec
+
+## Overview
+
+The Data2Vec model was proposed in [data2vec: A General Framework for Self-supervised Learning in Speech, Vision and Language](https://arxiv.org/pdf/2202.03555) by Alexei Baevski, Wei-Ning Hsu, Qiantong Xu, Arun Babu, Jiatao Gu and Michael Auli.
+Data2Vec proposes a unified framework for self-supervised learning across different data modalities - text, audio and images.
+Importantly, predicted targets for pre-training are contextualized latent representations of the inputs, rather than modality-specific, context-independent targets.
+
+The abstract from the paper is the following:
+
+*While the general idea of self-supervised learning is identical across modalities, the actual algorithms and
+objectives differ widely because they were developed with a single modality in mind. To get us closer to general
+self-supervised learning, we present data2vec, a framework that uses the same learning method for either speech,
+NLP or computer vision. The core idea is to predict latent representations of the full input data based on a
+masked view of the input in a selfdistillation setup using a standard Transformer architecture.
+Instead of predicting modality-specific targets such as words, visual tokens or units of human speech which
+are local in nature, data2vec predicts contextualized latent representations that contain information from
+the entire input. Experiments on the major benchmarks of speech recognition, image classification, and
+natural language understanding demonstrate a new state of the art or competitive performance to predominant approaches.
+Models and code are available at www.github.com/pytorch/fairseq/tree/master/examples/data2vec.*
+
+Tips:
+
+- Both Data2VecAudio and Data2VecText have been trained using the same self-supervised learning method.
+  In the case of Data2VecAudio, preprocessing is identical to [`RobertaModel`], including tokenization.
+
+This model was contributed by [edugp](https://huggingface.co/edugp).
