+# tweet-topic-19-single
+
+This is a roBERTa-base model  trained on ~90m tweets until the end of 2019 (see [here](https://huggingface.co/cardiffnlp/twitter-roberta-base-2019-90m)), and finetuned for single-label topic classification on a corpus of 6,997 tweets.
+The original roBERTa-base model can be found [here](https://huggingface.co/cardiffnlp/twitter-roberta-base-2019-90m) and the original reference paper is [TweetEval](https://github.com/cardiffnlp/tweeteval). This model is suitable for English.

+## Full classification example
+
+```python
+from transformers import AutoModelForSequenceClassification, TFAutoModelForSequenceClassification
+from transformers import AutoTokenizer
+import numpy as np
+from scipy.special import softmax
+
+    
+MODEL = f"cardiffnlp/tweet-topic-19-single"
+tokenizer = AutoTokenizer.from_pretrained(MODEL)
+
+# PT
+model = AutoModelForSequenceClassification.from_pretrained(MODEL)
+class_mapping = model.config.id2label
+
+text = "Tesla stock is on the rise!"
+encoded_input = tokenizer(text, return_tensors='pt')
+output = model(**encoded_input)
+
+scores = output[0][0].detach().numpy()
+scores = softmax(scores)
+
+# TF
+#model = TFAutoModelForSequenceClassification.from_pretrained(MODEL)
+#class_mapping = model.config.id2label
+#text = "Tesla stock is on the rise!"
+#encoded_input = tokenizer(text, return_tensors='tf')
+#output = model(**encoded_input)
+#scores = output[0][0]
+#scores = softmax(scores)
+
+
+ranking = np.argsort(scores)
+ranking = ranking[::-1]
+for i in range(scores.shape[0]):
+    l = class_mapping[ranking[i]]
+    s = scores[ranking[i]]
+    print(f"{i+1}) {l} {np.round(float(s), 4)}")
+
+```
+
+Output: 
+
+```
+1) business_&_entrepreneurs 0.8575
+2) science_&_technology 0.0604
+3) pop_culture 0.0295
+4) daily_life 0.0217
