Twitter RoBERTa-base Sentiment Analysis (safetensors)

This repository contains a safetensors-only version of the model:

cardiffnlp/twitter-roberta-base-sentiment-latest

The model performs sentiment classification on English tweets and predicts the following labels:

• Negative
• Neutral
• Positive

No architectural changes or retraining have been performed. The only modification is the conversion of model weights to the safetensors format.

Original Model

• Training Data: ~124M tweets (2018–2021)
• Task: Sentiment analysis (TweetEval benchmark)
• Reference Paper: TimeLMs
• Original Repository: TimeLMs GitHub
• Demo / Integration: TweetNLP

Label Mapping:

ID	Label
