A commentary on Micah Bregman et al.: A method for testing synchronization to a musical beat in domestic horses (Equus ferus caballus)

Sandy Venneman
2013 Empirical Musicology Review  
This commentary provides additional information related to equines and suggestions for strengthening the proposed protocol for testing synchronization to a musical beat in this species.  ...  For this reason it might be beneficial to look at the beat on the dominant forelimb in addition to the current protocol of counting the footfalls of both forelimbs.  ...  However, a strength of the proposed musical protocol is insuring that the test music chosen has a strong beat and that each horse has the physical ability to trot to the tempo chosen.  ...

A new hierarchical method for inter-patient heartbeat classification using random projections and RR intervals

Huifang Huang, Jie Liu, Qiang Zhu, Ruiping Wang, Guangshu Hu
2014 BioMedical Engineering OnLine  
The majority of previously proposed methods that take the above two aspects into consideration use the same features and classification method to classify different classes of heartbeats.  ...  It demonstrated better classification performance than existing methods. It can be regarded as a promising system for detecting VEB and SVEB of unknown patients in clinical practice.  ...  Although the proposed method was used for the detection of VEB and SVEB, class F beat and a few heartbeat types in a class could be detected in terms of the core idea of the method.  ...

Compositional Generalization for Primitive Substitutions

Yuanpeng Li, Liang Zhao, Jianyu Wang, Joel Hestness
2019 Proceedings of the 2019 Conference on Empirical Methods in Natural Language Processing and the 9th International Joint Conference on Natural Language Processing (EMNLP-IJCNLP)  
Conventional methods use a single representation for the input sentence, making it hard to apply prior knowledge of compositionality.  ...  It also beats human performance on a few-shot learning task. We hope the proposed approach can help ease future research towards human-level compositional language learning.  ...  Acknowledgments We thank Kenneth Church, Mohamed Elhoseiny, Ka Yee Lun and others for helpful suggestions.  ...
