# 🧠 Zero-Shot Text Classifier (Hugging Face Version)

A smart and lightweight web app built with **Gradio** and **Transformers** that classifies your input text into the most likely label — using **Zero-Shot Learning**.

## 🧠 About the Model
- **Pipeline**: `zero-shot-classification`
- **Model**: `facebook/bart-large-mnli`
- **Framework**: Hugging Face Transformers
- **Task**: Predict a relevant label even if the model wasn't trained on it

## 💡 Features
- Accepts custom comma-separated labels
- Returns top predictions with confidence scores
- Works in real-time — hosted via Hugging Face Spaces

## ⚙️ Instructions for Users
This app uses **zero-shot classification** to find the most relevant label based on your input and label list.

👉 **How to use:**
1. Enter a sentence or paragraph
2. Enter comma-separated labels like: `Technology, Sports, Food`
3. The app will return top labels with confidence scores

⚠️ **Note:**
- Avoid overlapping or vague labels. It may reduce prediction accuracy.
- For example, a sentence about economy and healthcare might score both **Finance** and **Health**.
- The answer may reflect multiple topics if the sentence spans more than one area — this is expected behavior in such cases.

✅ **Example 1:**
- **Text:** `Roger Federer won another grand slam title, cementing his legacy in tennis.`
- **Labels:** `['Politics', 'Fashion', 'Sports']`
- **Prediction:** `Sports — 99.2%`

✅ **Example 2:**
- **Text:** `The chef used fresh ingredients and spices to prepare a delicious Indian curry.`
- **Labels:** `['Food', 'Health', 'Travel']`
- **Prediction:** `Food — 88.9%`

✅ **Example 3:**
- **Text:** `Climate change is leading to rising sea levels and more frequent extreme weather events.`
- **Labels:** `['Environment', 'Fashion', 'Technology']`
- **Prediction:** `Environment — 88.5%`
