![]() ![]() In this competition we will try to build a model that will be able to determine different types of toxicity in a given text snippet. We will use Kaggle’s Toxic Comment Classification Challenge to benchmark BERT’s performance for the multi-label text classification. ![]() In the world of customer service, this technique can be used to identify multiple intents for a customer’s email. Multi-label classification has many real world applications such as categorising businesses or assigning multiple genres to a movie. On other hand, multi-label classification assumes that a document can simultaneously and independently assigned to multiple labels or classes. This is sometimes termed as multi-class classification or sometimes if the number of classes are 2, binary classification. Traditional classification task assumes that each document is assigned to one and only on class i.e. In this article, we will focus on application of BERT to the problem of multi-label text classification. This allows us to use a pre-trained BERT model by fine-tuning the same on downstream specific tasks such as sentiment classification, intent detection, question answering and more. The model is also pre-trained on two unsupervised tasks, masked language modeling and next sentence prediction. BERT is a bidirectional model that is based on the transformer architecture, it replaces the sequential nature of RNN (LSTM & GRU) with a much faster Attention-based approach. Perhaps the most exciting event of the year in this area has been the release of BERT, a multilingual transformer based model that has achieved state-of-the-art results on various NLP tasks. All these approaches allow us to pre-train an unsupervised language model on large corpus of data such as all wikipedia articles, and then fine-tune these pre-trained models on downstream tasks. ![]() Some of the key milestones have been ELMo, ULMFiTand OpenAI Transformer. Research in the field of using pre-trained models have resulted in massive leap in state-of-the-art results for many of the NLP tasks, such as text classification, natural language inference and question-answering. The past year has ushered in an exciting age for Natural Language Processing using deep neural networks. ![]()
