🚅 bullet: A Zero-Shot / Few-Shot Learning, LLM Based, text classification framework

---

---

Motivation

• Besides the fact that LLMs have a huge power in generative use cases, there is a use case that is quite frequently overlooked by frameworks such as LangChain: Text Classification.
• 🚅 bullet was created to address this. It leverages the power of ChatGPT, while removing any boilerplate code that is needed for performing text classification using either Zero Shot or Few Shot Learning.

Getting Started

1. Install bullet: pip install "git+https://github.com/rafaelpierre/bullet.git#egg=bullet&subdirectory=src"
2. Configure your OPENAI_API_KEY
3. You should be good to go

Zero-Shot Classification

from bullet.core.sentiment import SentimentClassifier


df_train_sample = df_train.sample(n = 50)

classifier = SentimentClassifier()
result = classifier.predict_pandas(df_train_sample)

Few-Shot Classification

# Define Few Shot examples

template = "Review: \"{review}\"\nLabel: \"{label}\""
examples = [
    template.format(
        review = row["text"],
        label = "POS" if row["label"] == 1 else "NEG"
    )
    for _, row
    in df_train.sample(3).iterrows()
]

df_test_sample = dataset["test"].to_pandas().sample(100)
reviews = df_test_sample.text.values

results = classifier.predict_few_shot(
    reviews = reviews,
    examples = examples
)
