Why? As the first author of several publications, more than half the reviews I received were not well thought out. This part of the process doesn't happen, Open Acess and self publishing websites exploited this fact for greater throughput.
>>machine learning
I would argue that the machine learning bloom in recent years is because of an availability of new technology from industry, supported by industry. This is also why they were able to tolerate less conventional venues for publication - as these were not viewed as mile markers for progress. Yet, when I look at more "settled" machine learning fields like speech, I see the same plethora of academic papers filled with useless crap.
Perhaps the growth of ML has nothing to do with Open Acess. There is although certainly there is an underlying profit motive for successful technologies, Google ain't going to use a technique that doesn't work.
>>raw clinical trial data
It would be great if it were published, and indeed many people would pay for quality trial data. I see OA and self-publishing of research results having no relation to authors withholding clinical data.
