In addition, BERT uses a next sentence prediction task that pretrains text-pair representations.īERT is a substantial breakthrough and has helped researchers and data engineers across the industry achieve state-of-art results in many NLP tasks. BERT takes in these masked sentences as input and trains itself to predict the masked word. First, one or more words in sentences are intentionally masked. What is BERT?įirst published in November 2018, BERT is a revolutionary model. For more information about BERT fine-tuning, see BERT Fine-Tuning Tutorial with PyTorch.

BERT FINETUNE HOW TO

This post demonstrates how to use Amazon SageMaker to fine-tune a PyTorch BERT model and deploy it with Elastic Inference. Amazon Elastic Inference enables attaching GPU-powered inference acceleration to endpoints, which reduces the cost of deep learning inference without sacrificing performance. Furthermore, customers prefer low inference latency and low model inference cost. Our customers often ask for quick fine-tuning and easy deployment of their NLP models. The Amazon SageMaker Python SDK provides open-source APIs and containers that make it easy to train and deploy models in Amazon SageMaker with several different ML and deep learning frameworks. Amazon SageMaker removes the heavy lifting from each step of the ML process to make it easier to develop high-quality models. Recently, we see increasing interest in using Bidirectional Encoder Representations from Transformers (BERT) to achieve better results in text classification tasks, due to its ability to encode the meaning of words in different contexts more accurately.Īmazon SageMaker is a fully managed service that provides developers and data scientists the ability to build, train, and deploy machine learning (ML) models quickly. Although these techniques have been very successful in many natural language processing (NLP) tasks, they don’t always capture the meanings of words accurately when they appear in different contexts. In the past, data scientists used methods such as tf-idf, word2vec, or bag-of-words (BOW) to generate features for training classification models. Text classification is a technique for putting text into different categories, and has a wide range of applications: email providers use text classification to detect spam emails, marketing agencies use it for sentiment analysis of customer reviews, and discussion forum moderators use it to detect inappropriate comments.
