Residual View
Two listening positions. One machine to understand.
Technical reportDCASE 2026 Challenge Task 2
A study of paired microphone representations for machine monitoring under noise. Public technical report for DCASE 2026 Task 2.
From two channels to a residual representation
A frozen audio encoder represents each channel. A weighted far-channel representation is subtracted from the near one; the distant microphone also captures the machine, so it is not a noise-only reference.
Reference selection and anomaly scoring
PRPS uses a projection residual to choose normal references. Their score is combined with the full-memory score. The linked report documents the experiments.
