# Text Embedding with data2vec

*author: David Wang*


<br />



## Description

This operator extracts features for text with [data2vec](https://arxiv.org/abs/2202.03555). The core idea is to predict latent representations of the full input data based on a masked view of the input in a self-distillation setup using a standard Transformer architecture.

<br />


## Code Example

Use the pre-trained model to generate a text embedding for the sentence "Hello, world.".

 *Write the pipeline in simplified style*:

```python
import towhee

towhee.dc(["Hello, world."]) \
      .text_embedding.data2vec() \
      .show()

```


<br />



## Factory Constructor

Create the operator via the following factory method

***data2vec()***

<br />



## Interface


**Parameters:**

​	***text:*** *str*

​	The text in string.



**Returns:** *numpy.ndarray*

​   The text embedding extracted by model.
