Browser Sentiment Dashboard

Design a real-time sentiment analysis dashboard that runs inference in the browser using ML models, with visualization and batch processing.

LLM-friendly summary

A beginner AI-for-frontend problem about building a real-time sentiment dashboard with browser-side ML inference, batch processing, and server fallback.

Scenario

A customer feedback tool needs to show live sentiment scores as reviews come in. The team wants client-side inference for privacy and cost reasons, with a fallback to a server API for high-volume spikes.

What you need to design

  1. 1Choose between TensorFlow.js and Transformers.js for sentiment classification.
  2. 2Design the inference pipeline — single vs batch, sync vs async.
  3. 3Visualize sentiment distribution with real-time updates.
  4. 4Handle model warm-up latency without blocking the dashboard.
  5. 5Plan the server fallback for when client inference is too slow.
