Build a Sequence Model for Sign-Language Word Recognition

FreeVerified credential2 weeksAdvanced

Overview

What this challenge is about.

You receive about 12,000 short (1-3s) webcam clips covering a 50-word vocabulary, with body+hand pose features pre-extracted (e.g., MediaPipe Holistic landmarks per frame). Build a sequence model (Transformer encoder or BiLSTM over pose features) for isolated-word classification. Compare against a frame-averaging baseline. Report top-1 and top-5 accuracy, plus a confusion matrix highlighting the most confusable word pairs. Deliver a 3-page evaluation memo plus a short demo screen recording of inference on 5 held-out clips.

The Brief

What you'll do, and what you'll demonstrate.

Train a sequence model that classifies isolated signs from pose features at production-grade accuracy.

Earning criteria — what you'll demonstrate

  • Apply sequence models to short multivariate time series
  • Use pose features as a compact intermediate representation for sign data
  • Diagnose confusable classes in fine-grained classification
  • Communicate results respectfully to a community-data-providing audience
