🧠 Prediction Model Overview

How the model generates predictions

The application is powered by a statistical n-gram language model.

Core idea - Training text is split into word sequences - The model learns which words most frequently follow others - For a given input, the model: - Extracts the last word - Predicts the most likely next word

✔ Simple
✔ Interpretable
✔ Designed for real-time use

📊 Predictive Performance

What the model does well

  • Trained on Twitter / News-style text
  • Uses frequency-based ranking
  • Returns a prediction whenever a known pattern exists

Performance characteristics - Strong accuracy for common phrases - Lower accuracy for rare or unseen inputs - Optimized for speed and reliability

⏱ Average response time: under 1 second

🖥️ Product Experience

How users interact with the app

  1. Enter a short phrase
  2. Click Predict
  3. Instantly receive the next word

Design focus - Clean, minimal interface - No technical knowledge required - Model is preloaded for fast response
