By “simple text classification task,” we mean a task in which you want to classify/categorize portions of text that are roughly one sentence to a paragraph in length. Obligatory Bert image. BERT's final layers can then be fine-tuned on a task of your choosing that will benefit from the rich representations of language it learned during pre-training. Abstract: The recently proposed BERT~\citep{devlin2018bert} has shown great power on a variety of natural language understanding tasks, such as text classification, reading comprehension, etc. What is Analytics Zoo? Analytics Zoo provides a unified data analytics and AI platform that seamlessly unites TensorFlow, Keras, PyTorch, Spark, Flink and Ray programs into an integrated pipeline, which can transparently scale from a laptop to large clusters to process production big data. In this article, we will focus on application of BERT to the problem of multi-label text classification. They were able to conquer tasks like storing and entering text, but language capabilities were faced with difficulty. BERT can achieve high accuracy with small sample size (e. Google's documentation on BERT is generally good, but how to use BERT on a simple text classification task isn't immediately obvious. This paper extends the BERT model to achieve state of art scores on text summarization. Structure of the code. BERT can be used to generate word vectors and Equation 1 above can be used to obtain a document vector. 1 Python : 3.
