pass your inputs and labels in any format that model.fit() supports! If, however, you want to use the second
format outside of Keras methods like fit() and predict(), such as when creating your own layers or models with
the Keras Functional API, there are three possibilities you can use to gather all the input Tensors in the first

Overview

The Data2Vec model was proposed in data2vec: A General Framework for Self-supervised Learning in Speech, Vision and Language 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


Overview

 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


Overview

 predominant approaches.
Models and code are available at www.github.com/pytorch/fairseq/tree/master/examples/data2vec.
Tips:
Data2VecAudio, Data2VecText, and Data2VecVision have all been trained using the same self-supervised learning method. For Data2VecAudio, preprocessing is identical to Wav2Vec2Model, including feature extraction For Data2VecText, preprocessing is identical to RobertaModel, including tokenization. For Data2VecVision, preprocessing is identical to BeitModel, including feature extraction.
This model was contributed by edugp and patrickvonplaten.
sayakpaul and Rocketknight1 contributed Data2Vec for vision in TensorFlow.
