BERT

BERT may refer to any of the following:

1. Short for bit error rate tester, a BERT is a device that performs a bit error rate test, a procedure that calculates the error rate of a transmission.

Most BERTs are specialized, standalone systems, but they can also run from a desktop computer. A BERT works by generating a known pattern of binary digits, which it transmits through a communication system. Then, it compares the received pattern with the original one to determine the rate of bit errors. If any errors are found, they are counted as a ratio, like 1 in 10,000 or 1 in 100,000.

2. Released by Google in 2018, BERT (Bidirectional Encoder Representations from Transformers) is a machine-learning technique for natural-language processing. Essentially, BERT is a tool that helps computers better understand human language.

BERT is designed to understand the context of words in a sentence by considering the surrounding words before and after. This bidirectional approach allows it to capture the nuances of language more effectively. BERT is pre-trained on a large data set of text, nearly 2.5 billion words from Wikipedia and 800 million words from BookCorpus. Its architecture is based on the transformer model, a standard in many NLP (Natural Language Processing) applications.

BERT can then be fine-tuned for specific natural-language processing tasks, such as text classification, NER (Named-Entity Recognition), and answering questions. BERT is significant in that it has achieved state-of-the-art performance on various NLP tasks. Some of these benchmarks include the SQuAD (Stanford Question Answering Dataset), GLUE (General Language Understanding Evaluation), and SWAG (Situations With Adversarial Generations).
