   Sure there will be a (ton??) of startups using these things, but my point is that it will not be nearly as prevalent as general statistics and predictive modeling. Which one do you think will be more common: 1) companies using speech reco

   I think machine learning masquerading as AI is definitely over-hyped. The real revolution is open source predictive modeling and statistical techniques becoming commonplace. Creating statistical models is much more useful and applicable to

   The distinguishing factor between those two roles that I have noticed is data scientists build predictive models and use statistics somehow, while analysts are relegated to the 'grunt' work like cleaning data, building reports, et

   I feel that most of the time candidates just want to hear something that puts the situation out of their control, and therefore wasn't merit based. It's always easier to hear "I'm breaking up with you because I'm mo

   It depends on what you mean by 'production'. I've had great success setting up my data collection, engineering and predictions in batch processes. I agree though, I would never try to use R with a REST API, but I don't t

   Yes the reason we decided not to include that in the post is that it wouldn't account for very much of the person's time, but it could absolutely produce a hang up if handled incorrectly. We could also have had an account manager

   Very true - there are often unofficial qualifications that aren't listed in the job posting too - things that would be strange to put into the official posting. We were hiring an analyst at my old company who needed to be tough. The jo

   I work in this space, and this study is getting a lot of attention. At the end of the day, colleges don't care. They have their pell eligibility quotas, their ethnicity ratio considerations, net tuition revenue requirements, etc etc. T

    They probably trained the model with audio, then told it what to say using text inputs. That made me do a double-take at first too, it's a pretty misleading wording.

    I wonder if the Wagner-Fischer algorithm could be vectorized using substring functions... It doesn't seem trivial. https://en.wikipedia.org/wiki/Wagner%E2%80%93Fischer_algorit...

    I agree this author seems more interested in self-promotion than anything else. However, I don't think the purpose of this book is to cover these subjects in their entirety. Most of the time, with books like these, I would just like to

    Excessive self-promotion aside, I think high level documents like this are more important than people give them credit for. Computer science is: 1) Daunting to beginners 2) Changing constantly It is absolutely a field where people suffer fr

    Yes, it does. However, it can usually be offset by some adjustment measure. The same thing happens when you take the log of your target variable and run a regression with RMSE as your loss, then try to get your predictions by taking e^predi

    I find the authors assertion lacking. The only reason the Facebook 10 year meme was immediately distrusted is because Facebook's image has already been shot. Think about how many other developing technologies people just can't wai

    I believe what he is getting at is that there is a limit on certain space times that are accessible to a given observer. Imagine an alien race (or a point in space) that is 10M light years away. We want to obtain information about the curr
