BERT

As explained in Machine Learning Algorithms in Depth

BERT is a pretrained bidirectional transformer language model designed to learn contextual representations of text.

BERT is a pretrained bidirectional transformer language model that learns contextual representations of text for natural language processing tasks. section 11.5

Its practical role is transfer learning: fine-tune the pretrained model with one additional output layer instead of designing substantial task-specific architectures. section 11.5

BERT supports tasks including:

Task adaptation

Start with pretrained BERT, attach one output layer, and fine-tune the resulting model for question answering or language inference. section 11.5

How Machine Learning Algorithms in Depth covers it

How deep it goes
Identifies BERT’s transfer-learning strategy and applications but does not derive its architecture or training procedure.
Examples
Uses question answering and language inference as concrete fine-tuning applications.
What you can do after
Apply it via fine-tuning with one additional output layer for downstream language tasks.
How it connects
Connects BERT with transformer models, machine translation, question answering, and language inference.
