This is PyTorch based RoBERTa pre-trained model trained on tweeteval dataset which contains ~12,000 tweets for the sentiment classification tasks with three classes being positive, negative, neutral sentiments. TweetEval Dataset consists of seven heterogenous tasks in twitter, all framed as multi-class tweet classification.One of the used for this demo is Sentiment Analysis. The model can be downloaded from hugging face: https://huggingface.co/cardiffnlp/twitter-roberta-base-sentiment-latest?text=Covid+cases+are+increasing+fast%21

In this Interactive demo, the user can input text and submit to get the corresponding sentiment class probabilities. This web app is developed using Gradio Python library.
