Electrocardiogram (ECG) and phonocardiogram (PCG) signals reflect the electrical mechanical activities of heart, respectively. Although studies have documented that some abnormalities in ECG PCG are associated with coronary artery disease (CAD), only few researches combined two for automatic CAD detection. This paper aims to differentiate between non-CAD groups using simultaneously collected signals. To entirely exploit underlying information these signals, a novel dual-input neural network...

Retrieving relevant targets from an extremely large target set under computational limits is a common challenge for information retrieval and recommendation systems. Tree models, which formulate as leaves of tree with trainable node-wise scorers, have attracted lot interests in tackling this due to their logarithmic complexity both training testing. Tree-based deep models (TDMs) probabilistic label trees (PLTs) are two representative kinds them. Though achieving many practical successes,...
