Using its latent space, it can be repurpossed for various NLP tasks, such as sentiment analysis. BERT_for_Sentiment_Analysis A - Introduction In recent years the NLP community has seen many breakthoughs in Natural Language Processing, especially the shift to transfer learning. BERT is a method of pre-training language representations, meaning that we train a general-purpose "language understanding" model on a large text corpus (like Wikipedia), and then use that model for downstream NLP tasks that we care about (like question answering). Sentimental analysis is the use of Natural Language Processing (NLP), Machine Learning (ML), or other data analysis techniques to analyze the data and provides some insights from the data. A big challenge in NLP is the shortage of training data. Financial news and stock reports often involve a lot of domain-specific jargon (there's plenty in the Table above, in fact), so a model like BERT isn't really able to . BERT For Sentimental Analysis using transformer library - GitHub - Muaz65/Sentimental-Analysis-Using-BERT: BERT For Sentimental Analysis using transformer library Note that the first time you run this script the sizable model will be downloaded to your system, so ensure that you have the available free space to do so.
