Topic-xDistil is a model based on xtremedistil-l12-h384-uncased fine-tuned for classifying the topic of news headlines on a dataset annotated by Chat GPT 3.5. It is built, together with Sentiment-xDistil, as a tool for filtering out financial news headlines and classifying their sentiment. The code used to train both models and build the dataset are found here.

Notes: The output labels are either Economics or Other. The model is suitable for English.

Performance Results

Here are the performance metrics for both models on the test set:

Model	Test Set Size	Accuracy	F1 Score
`topic-xdistil-uncased`	32 799	94.44 %	92.59 %
`sentiment-xdistil-uncased`	17 527	94.59 %	93.44 %

Data

The training data consists of ~600k news headlines and tweets, and was annotated by Chat GPT 3.5, which has shown to outperform crowd-workers for text annotation tasks.

The sentence labels are defined by the Chat GPT prompt as follows:

python

"""
[...]
    - Economic headlines generally cover topics such as financial markets, \
 business, financial assets, trade, employment, GDP, inflation, or fiscal \
and monetary policy.
    - Non-economic headlines might include sports, entertainment, politics, \
science, weather, health, or other unrelated news events.
[...]
"""

Example Usage

Here's a simple example:

python

from transformers import AutoTokenizer, AutoModelForSequenceClassification

model = AutoModelForSequenceClassification.from_pretrained("hakonmh/topic-xdistil-uncased")
tokenizer = AutoTokenizer.from_pretrained("hakonmh/topic-xdistil-uncased")

SENTENCE = "Global Growth Surges as New Technologies Drive Innovation and Productivity!"
inputs = tokenizer(SENTENCE, return_tensors="pt")
output = model(**inputs).logits
predicted_label = model.config.id2label[output.argmax(-1).item()]

print(predicted_label)

Economics

Or, as a pipeline together with Sentiment-xDistil:

python

from transformers import pipeline

topic_classifier = pipeline("sentiment-analysis",
                            model="hakonmh/topic-xdistil-uncased",
                            tokenizer="hakonmh/topic-xdistil-uncased")
sentiment_classifier = pipeline("sentiment-analysis",
                                model="hakonmh/sentiment-xdistil-uncased",
                                tokenizer="hakonmh/sentiment-xdistil-uncased")

SENTENCE = "Global Growth Surges as New Technologies Drive Innovation and Productivity!"
print(topic_classifier(SENTENCE))
print(sentiment_classifier(SENTENCE))
