Mi Air Purifier 2
Signal trajectory
realSignal 6.1 → 14.0 across 39 readings (+7.9). Composite of press, GitHub velocity, community heat, liveness and funding.
Cross-sectional profile
percentile rank vs 79,105 modeled productsPercentiles computed over the modeled cohort (embedding + signal + tags). Sparse dimensions — network and press — reflect that most products have zero, so a single edge or mention lifts the rank; read those with the coverage flag.
Mortality outlook
model estimateThis is a model estimate, not a verdict. 78,505 of the 79,105 modeled products are unlabeled and scored by the model only.
- LightGBM · binary mortality (dead vs surviving)
- Held-out AUC 0.71 · CV AUC 0.79 ± 0.05 · Brier 0.21
- Trained on 600 verified labels (150 dead / 450 surviving)
- Leakage-guarded: excludes status, discontinued_year, profile_maturity
- Top drivers: tag breadth, signal, vintage, liveness, business model
n=600 is thin → 95% CI on AUC ≈ ±0.10. Treat as a directional signal, not a calibrated probability.
Analyst read
generated from the metrics above · no external narrativeMi Air Purifier 2 sits in the 1th percentile of Launch Sentinel's 79,105-product universe by signal, ranked #2,197 of 5,243 in Hardware. The mortality model puts its probability of going inactive at 82% — a model estimate with a wide confidence band. It has no curated competitive-alternative edges yet, so the comparable set below is functional tag-similarity — read it with the confidence flags. Signal momentum is roughly flat.

Confidence reflects source and category coherence: curated = an editorially linked alternative; similar = strong functional tag-overlap in the same category; tag-overlap = shared tags only and may be noisy. Signal & P(dead) are real / model.
