CosmicWatch: Building an Open-Source AI Observatory for Unusual Radio Signals

说明与用途

CosmicWatch 自动检测异常射电信号，减轻 SETI 研究人员的工作量。

问题

Radio telescopes generate massive data streams, making manual inspection of unusual signals impractical.

结果

CosmicWatch reduces manual inspection effort by automating detection and prioritization of unusual radio‑signal candidates, providing clear explanations for each flag.

工作流

• 1. Ingest raw .fil/.h5 files via BLIMPY.
• 2. Apply CNN to detect candidate signals.
• 3. Run Isolation Forest to flag statistical anomalies.
• 4. Score candidates for prioritization.
• 5. Generate LLM explanations for flagged candidates.
• 6. Visualize results on a FastAPI/React dashboard.

证据

Radio telescopes generate huge amounts of data, making manual inspection difficult.

来源

CosmicWatch uses a lightweight CNN for signal detection, Isolation Forest for anomaly detection, candidate scoring for prioritization, and an open-weight LLM for explaining why a candidate was flagged.

来源

CosmicWatch does not claim to detect aliens. Instead, it identifies unusual radio‑signal patterns that researchers can investigate further, with SETI as one of its key applications.
