You have successfully built a transformers network with a pre-trained BERT model and achieved ~95% accuracy on the sentiment analysis of the IMDB reviews dataset! If you are curious about saving your model, I would like to direct you to the Keras Documentation The syntax @app.route('/score', methods=['PUT']) lets Flask know that the function, score, should be mapped to the endpoint/score.The methods list is a keyword argument that tells us what kind of HTTP requests are allowed. We'll be using PUT requests to receive sentences from a user. In function score, we get a score in dictionary form, since it can be easily converted to a JSON string

We fine-tune a BERT model to perform this task as follows: Feed the context and the question as inputs to BERT. Take two vectors S and T with dimensions equal to that of hidden states in BERT. Compute the probability of each token being the start and end of the answer span. The probability of a token being the start of the answer is given by a. Sentiment Classification Using BERT. BERT stands for Bidirectional Representation for Transformers, was proposed by researchers at Google AI language in 2018. Although the main aim of that was to improve the understanding of the meaning of queries related to Google Search, BERT becomes one of the most important and complete architecture for. By adding a simple one-hidden-layer neural network classifier on top of BERT and fine-tuning BERT, we can achieve near state-of-the-art performance, which is 10 points better than the baseline method although we only have 3,400 data points. In addition, although BERT is very large, complicated, and have millions of parameters, we only need to.
