BERT
BERT is a Google-developed AI model that understands text by looking at words in relation to all others in a sentence.
BERT is a way for computers to understand human language. It was created by Google.
Before BERT, computers often read text one word at a time. BERT looks at all the words in a sentence together. This helps it understand the meaning much better, especially when words can have different meanings depending on the context. For example, it can tell the difference between "bank" as in a river bank and "bank" as in a financial institution.
BERT (Bidirectional Encoder Representations from Transformers) is a transformer-based model developed by Google. It excels at natural language understanding tasks by pre-training on a massive text corpus using a masked language model objective and next sentence prediction. This bidirectional approach allows it to learn context from both left and right sides of a word simultaneously, a significant improvement over previous unidirectional models.
While BERT itself is an older model, the principles of transformer architectures and bidirectional context it popularized are foundational to many current large language models. Understanding BERT helps explain the evolution of NLP and the capabilities of modern AI systems.

You can see BERT's capabilities by using a sentiment analysis tool online. Input a sentence and see if the tool correctly identifies whether the sentiment is positive, negative, or neutral, demonstrating BERT's understanding of word context.
