Using a pre-trained BERT model, we generate embeddings for each token:

deep_feature = [0.23, 0.41, ..., 0.57]

Tokenized text:

To generate a deep feature for the text, we can use a text embedding technique such as Word2Vec or BERT. Let's assume we're using a pre-trained BERT model to generate embeddings.

This is a dense vector representation of the input text, which can be used for downstream tasks such as text classification, clustering, or information retrieval.

Let's use mean pooling:
