This repo contains a PyTorch implementation of a pretrained BERT model for multi-label text classification. We will use Kaggle's spam classification challenge to measure the performance of BERT in multi-label text classification. Text classification using BERT. Be it questions on a Q&A platform, a support request, an insurance claim or a business inquiry - all of these are usually written in free form text and use vocabulary which might be specific to a certain field. This challenge consists in tagging Wikipedia comments according to several "toxic behavior" labels. Logs. label. In this article, we will focus on application of BERT to the problem of multi-label text classification. Save and deploy trained model for inference (including on AWS Sagemaker). In Multi-Label Text Classification (MLTC), one sample can belong to more than one class. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Setup Install the BERT using !pip install bert-tensorflow Creating Multi-label Text Classification Models There are two ways to create multi-label classification models: Using single dense output layer and using multiple dense output layers. : A value of 0 or 1 depending on positive and negative sentiment. The transformer includes 2 separate mechanisms: an encoder that reads the text input and a decoder that generates a prediction for any given task. Fine-Tune BERT for Text Classification with TensorFlow Figure 1: BERT Classification Model We will be using GPU accelerated Kernel for this tutorial as we would require a GPU to fine-tune BERT. 4.3s. Where do we start? A comment might be threats . Your Product.
