基于PPG的心率估计问题,简单问题还是复杂问题?

昨天我发了一篇帖子,提到自己最近又发表了一篇论文  ,竟然有人xmjdh地回复说,“是造SCI,把简单问题复杂化”。好大的口气!竟然认为这是一个简单问题。


首先,我作为三星研发经理,发不发表SCI文章对我一点用途没有。对公司职员来说,业绩的考评是项目完成情况和专利的多少,和文章没有任何关系。我没有任何motivation来制造SCI文章。我更不可能像国内一些高校那样,因为发表一篇SCI就拿1万块。 况且,国外学术界谁会关心什么SCI不SCI的。  


其次,目前为止,无论是文献还是最近结束的IEEE Signal Processing Cup,都没有中国人或者海外华人在这个问题(运动中的心率估计)上发表高性能的算法或者在这个比赛中拿到名次。所以,说什么“造SCI,把简单问题复杂化”的人,有骨气就不如写篇文章让大家看看你的算法的性能?


再次,IEEE Signal Processing Cup里的数据,毕竟是针对本科生的竞赛,数据经过挑选,不是特别难,以便让本次竞赛更加适合本科生的水平。真正的要在智能手表上跑,难度不知道大了多少倍。下面转载一个新闻,说苹果的Apple Watch通过三方检查,显示在fitness tracking/health monitoring上的性能非常不稳定:

APPLE WATCH ISSUES PUT WEARABLE ACCURACY IN SPOTLIGHT

This week the Wall Street Journal reported Apple’s announcement about its highly anticipated watch not featuring planned health monitoring features.  It is unclear if the glucose tracker ApplySci detailed this month will still be included.

Apple Watch was envisioned as a device  full of sensors that could measure heart rate, stress levels, blood pressure and more.  After testing, many of these sensors performed erratically.  The skin conductivity feature did not work on dry skin or hairy arms, and results varied depending on how tight the watch was worn on the wrist.

This is, actually, great news.  There are many “health” monitors on the market, making claims of accuracy that may or may not be substantiated.  Crowdfunding sites are filled with toys and gadgets that promise the world, and occasionally deliver.  May Apple’s decision not to release its health monitoring features prematurely lead to a world of reliable wearables that can improve or save lives.
