Gravitational-wave population studies must repeatedly ask whether each of millions of simulated binary black holes would be detected, and each answer conventionally requires generating a waveform and computing a noise-weighted inner product. asmaNet maps 11 binary parameters directly to the phase-averaged optimal signal-to-noise ratio for a single detector, beating MLP, 1D-ResNet and Transformer-encoder baselines at every dataset scale from 100k to 1M samples under a matched training protocol with only about 732k parameters. On the 1M-sample held-out test set it reaches 99.29% accuracy after rank-preserving monotonic calibration, sustaining roughly 120,000 SNR evaluations per second on one GPU.

In a 401-patient multicentre European prospective pulmonary arterial hypertension (PAH) cohort, adding right ventricular echocardiographic parameters—especially right ventricular-pulmonary arterial (RV-PA) coupling indices—to the ESC/ERS and REVEAL 2.0 risk scores improved the c-index for morbi-mortality prediction from 0.73 to 0.78 and from 0.74 to 0.79, respectively (P<0.01), with machine learning identifying RV-PA coupling as the most influential dimension.
